Section 2 - Configuration Guide

Configuration guide 2-1 Section 2 – Configuration Guide Venus is an extremely flexible product line with a wide range of packaging options that allow you to design a system that is specifically tailored to the needs of each individual application. This document is designed to serve as a guide to help you choose the best Venus Routing Switcher for your system requirements. This guide is laid out in two main sections. The first section covers pre–configured systems, which are designed to provide the most economical way to package the more commonly used matrix sizes. The pricing of the configured systems is adjusted to reflect the cost savings of building stock units in quantity as opposed to building a system from scratch.

You should use these switchers whenever possible to get the best price and delivery. The second section describes the building blocks of the Venus switcher and provides the information you need to put together a system from these components.

This document covers only the actual switching matrix portion of the routing switcher system. For information on the control system, terminal equipment, or other products that may be required in the overall system design, refer to the appropriate product literature. For performance specifications and dimensions, see Section 1 of this manual. Front View Rear View (32x32 VAA) VENUS CHASSIS

Configuration guide 2−2 Pre–Configured Switchers This section describes various switchers that are pre–configured with the appropriate combination of these components to form complete switching systems.

In all cases, pre–configured switchers are prewired to the maximum expansion size for their particular matrix configuration. This means that there are no modifications necessary to the chassis, connector panels, or I/O cabling when expanding the matrix from the initial size up to the maximum size. Note: Pre–configured Venus Audio Matrices are all built with the AS 400 and AO 400 Series audio cards which are STEREO cards, with two channels on each card. When you see AA in the following descriptions, this is a STEREO matrix with full mix/swap capabilities. 32 Output Switchers These switchers use a compact 32x32 Configura- tion Board to allow multiple signal levels to be installed in a single chassis.

Configurations include component video plus ste- reo audio, composite video plus stereo audio, and separate video and stereo audio. All switchers in this series are fitted to the maximum matrix size of 32x32 and are thus not expandable. Each 32x32 matrix group occupies 4 of the chassis’ 24 available card slot positions. This means that the CVAA matrix uses 5 x 4 or 20 slots, the VAA matrix uses 2 x 4 or 8 slots and the single level matrices use 4 slots each. Unused slots may be equipped with additional matrix levels; contact the factory for details.

Configuration guide 2−3 64 Output Switchers These switchers use two 64x32 Configuration Boards for Audio and one 64x64 Configuration Board for Video to provide a larger matrix size – still in a single chassis. Combined Video/Stereo Audio and separate Video or Stereo Audio versions are available in this configuration. Each 64x64 matrix group occupies 12 of the chas- sis’ 24 available card slot positions. This means that the VAA matrix uses all 24 positions while the single level matrices each use 1/2 of the available space.

Unused slots may be equipped with additional matrix levels; contact the factory for details on your individual requirements.

The 160x32 Configuration Board occupies 12 card positions while the 160 x 64 Configu- ration Board occupies 24 card positions. Each of these switchers fully utilize the available space in the chassis with no room for additional matrix groups. Due to the space required on the rear panel for the stereo audio connections, it is not possible to have more than 128 inputs on the AA matrices in this series without using a special external connector arrangement. For this reason, AA matrices in this section are prewired only to the 128 input size. The 144 and 160 input matrices include the special external connectors.

Refer to Audio Components section for details on the AP–410 External Connector Arrangements.

Configuration guide 2−4 96 Output Switchers These switchers use three 96x32 Configuration Boards in each chassis to allow for a matrix of a single signal type as large as 96x96 in one card cage.

The 96x32 Configuration Board occupies 8 card positions — 1/3 of the available space in the chassis. While mixing matrix types with this configuration is possible, the standard packages use a separate chassis for each signal type.

Configuration guide 2−5 96 Output Expandable Switchers These switchers use two chassis fitted with 160x32 Configuration Boards for Audio and 160x64 Configu- ration Boards for Video for additional output capacity. These switchers have provisions to hold four sets of crosspoint / output cards. The first three sets are sup- plied in these switchers while the fourth is prewired only – no cards are fitted in these positions. In Video switchers, the unused slots are fitted with VL 400 Bus Loader cards to maintain the electrical charac- teristics of the input bussing.

Since the 160x64 configuration occupies 24 card posi- tions, each of these switchers fully utilize the available space in the chassis with no room for additional matrix groups.

Due to the large number of inter–frame cables required to make up a matrix of this size, Thomson strongly rec- ommends that the customer furnish racks for the matrix to be installed into at the factory. This avoids the necessity of tearing the switcher down to ship it and then re–installing all of the cabling on–site.

Configuration guide 2−6 128 Output Switchers These switchers use two chassis fitted with 160x32 Configuration Boards for Audio or 160x64 Config- uration Boards for Video to provide additional out- put capacity. All matrix card positions are filled in this series of switchers. Since the 160 x 64 Configuration Board occupies 24 card positions, each of these switchers fully uti- lize the available space in the chassis with no room for additional matrix groups. Due to the large number of inter–frame cables required to make up a matrix of this size, Thomson strongly recommends that the customer furnish racks for the matrix to be installed into at the fac- tory.

This avoids the necessity of tearing the switcher down to ship it and then re–installing all of the cabling on–site.

Venus Routing Switcher Components

Configuration guide 2−7 Fixed Configuration Systems A limited number of Venus Routing Switcher configurations are available on the special Fixed Configuration program. These are switchers of particular sizes and matrix types that are built for stock and available for “off-the-shelf” delivery at a very special price. Whenever you are specifying a Venus system, you should check the Fixed Configuration list first. If you are able to use one of these pre–packaged switchers, you can save a considerable amount on the purchase price and be assured of the fastest possible delivery.

Please be aware that since these units are built for stock, having the factory to make modifications, additions or deletions to a Fixed Configuration Switcher is not possible.

If the Fixed Configuration Switcher list does not contain a unit that you can use, you will need to find one in the pre–configured listings, or configure your own special–order unit. The components and configuration patterns used in these switchers are, in all cases, exactly the same as you will find in the other Venus switchers, both pre–configured and special order units. Field upgrades, expansions, or re–configurations can be accomplished following the normal Venus configuration rules.

Configuration guide 2−10 Venus Routing Switcher Components This section of the Configuration Guide contains descriptions of the various components that make up a Venus Routing Switcher and provides tips on selecting and using these components when you are laying out a switching system. The components are grouped by matrix type, placing all of the components that are needed to make a particular type of matrix into one section for easy reference. At the end of this section is a checklist that provides a step–by–step guide through the process of selecting the components that are required to build a Venus system.

A worksheet listing all of the items is also provided for use in calculating the system price.

All Venus Routing Switchers are made up of various combinations of the following building blocks: S Chassis – A 19–inch rack mount frame 11 RU (19.25 inches) in height. S Power Supply – automatic input voltage selection. (redundant supplies are standard) S Crosspoint Module – Sixteen input channels, thirty–two outputs. (HD/SD, Mono Audio and AES/EBU digital audio are 32x32.) S Output Module – Sixteen output channels. (HD/SD and AES/EBU digital audio are 32 output channels.) S Configuration Board (also known as the “ZIF” board) – A PC Board / Connector assembly that carries the signals from the Crosspoint Modules to the Output Modules.

S I/O Cabling – Connector panels and cables to bring signals into and out of the matrix.

Configuration guide 2−11 ANALOG VIDEO COMPONENTS RF 400 Chassis RF 400/32 F7–023700–565 RF 400/64 F7–023700–566 The Venus chassis provides the framework for the switcher’s uniquely flexible architecture.

The chassis contains a motherboard which provides a connection plane between the matrix boards and the input/output wiring assemblies. Each chassis provides mounting locations for two power supplies and 24 matrix boards. The rear panel area of the chassis provides mounting locations for six standard rear panel assemblies and two option modules. The 32–output chassis (RF 400/32) is the standard model for most switcher configurations. The motherboard in this model is designed to accept any combination of matrix cards and is used in building the majority of switchers where multiple matrix blocks are to be mounted in a single chassis.

The RF 400/64 is a special version which has a 64–output motherboard. This motherboard has video input looping circuitry that connects pairs of adjacent crosspoint card slots to the same input, saving the expense of separate looping cables and connectors. This version of the chassis is required wherever one of the 64–Output Configuration Boards is used. PS 400C Power Supply F7–023700–137 Power for each RF 400 frame is provided by one PS 400C. This unit features automatic input voltage selection, making it usable on any line voltage standard. The PS 400C is VDE approved.

If redundant power is required, two PS 400C units can be mounted in each frame.

All output voltages from each supply are bussed to all card positions, selection between the supplies is made automatically on each board. VS 400 Video Crosspoint Board F7–023700–007 Each VS 400 receives 16 analog video inputs from the chassis motherboard and switches them onto one of 32 output busses for processing by the Video Output Board. V0 410 Video Output Board F7–023700–009 The VO 410 is a 16–channel output amplifier / buffer module with an on–board 16x1 monitor switcher that allows one of the output channels to be selected onto an independent monitor bus.

VIDEO CONFIGURATION BOARDS The Configuration Board (also known as the ZIF Board) connects the outputs of the Crosspoint Boards to the inputs of the Output Boards. These boards are made up of large high–density Zero Insertion Force (ZIF) connectors that mate with the signal pins on the top of each of the matrix boards. The number of these connectors on the board and the pattern by which they are connected determines the physical configuration of the matrix section. The following Video Configuration Boards are available: Size Part Number Cards: Slots Types 32x32 F7–023700–003 4 2 VS / 2 VO 64x32 F7–023700–004 6 4 VS / 2 VO 96x32 F7–023700–042 8 6 VS / 2 VO 64x64 F7–023700–002 12 8 VS / 4 VO 160x32 F7–023700–043 12 10 VS / 2 VO 160x64 F7–023700–001 24 20 VS / 4 VO 352x32 F7–023700–005 24 22 VS / 2 VO The 64–output Configuration Boards are used in conjunction with the 64–output chassis.

VP 400A Video Rear Panels 01–044797–001 The Video Rear Panel contains 64 BNC connectors arranged in four rows of sixteen and is used for connecting both inputs and outputs. A 65th connector is provided for use by the output monitor bus as required. The BNC connectors are wired via a PC assembly to eight multi–pin connectors, each of which carries eight signal lines.

Configuration guide 2−12 The Video Rear Panel is 2.75” wide, filling 1/6 of the available mounting space at the rear of the chassis. One panel is required for each 64 signals into/out of the matrix. VP 410 Video Rear Panels 01–046283–001 The VP 410 Video Rear Panel provides 96 BNC Connectors, plus the output monitoring connector. This panel uses 1/4 of the available mounting space at the rear of the chassis. A combination of VP 410 and VP 400A panels can be used to configure systems with odd multiples of 32 inputs or outputs.

Video Input Cables 22” Length 01–043988–001 26” Length 01–044390–001 36” Length 01–045713–001 Coaxial cables built with subminiature coax are used for all internal wiring of the video signals in the Venus system.

The Input Cable kit connects the inputs from the rear panel to the chassis motherboard. Each Video Input Cable kit consists of eight separate subminiature coax cables wired to a connector that mates with the Video Rear Panel’s multi–pin connectors at one end and to the chassis motherboard’s connectors at the other end. One kit is required for each eight inputs to the matrix.

Video Looping Cables 01–043989–001 The Video Looping Cables are used to connect inputs from one matrix block to another, either within a frame or between two frames. The Video Looping Cable assembly consists of eight coax cables terminated at both ends with a connector that mates with the motherboard pins. One looping cable assembly is required for each intermatrix connection of eight inputs, except when using 64–output chassis where input looping within a matrix block is handled by the motherboard.

Video Output Cables 01–043990–001 Each Video Output Cable assembly consists of eight separate subminiature coax cables wired to a connector that mates with the Video Rear Panel’s multi–pin connectors at one end and to the chassis motherboard’s connectors at the other end.

One assembly is required for each eight outputs from the matrix. VT 400 Video Terminators 01–044049–001 Each of the 8–wire input cable assemblies must be terminated with a VT 400 terminator that is installed on the motherboard’s looping connector adjacent to the end of the last looping cable in the input chain.

VO 410 Input signals are connected VP 400A VS 400 VO 410 Video Output Cables (8 ea.) to these crosspoint cards via the motherboard. 64 x 64 Video Matrix Signal Interconnect Wiring (using 64-output chassis and 64x64 ZIF Board) Whenever an input looping chain is connected to a crosspoint board slot where no board is installed, a bus loader must be installed in place of the crosspoint card at that location to preserve the electrical characteristics of the input chain.

Configuration guide 2−14 ANALOG AUDIO COMPONENTS RF 400 Chassis RF 400/32 F7–023700–565 RF 400/64 F7–023700–566 The Venus chassis provides the framework for the switcher’s uniquely flexible architecture.

The chassis contains a motherboard which provides a connection plane between the matrix boards and the input/output wiring assemblies. Each chassis provides mounting locations for two power supplies and 24 matrix boards. The rear panel area of the chassis provides mounting locations for six standard rear panel assemblies and two option modules. The 32–output chassis (RF 400/32) is the standard model for most audio switcher configurations. The motherboard in this model is designed to accept any combination of matrix cards and is used in building the majority of switchers where multiple matrix blocks are to be mounted in a single chassis.

The RF 400/64 is a special version that has a 64–output motherboard. This chassis is used with certain video matrix configurations and is fully compatible with all audio configurations, permitting audio matrix blocks of any size to be mounted into a frame containing 64–output video blocks. PS 400C Power Supply F7–023700–137 Power for each RF 400 frame is provided by one PS 400C. This unit features automatic input voltage selection, making it usable on any line voltage standard. The PS 400C is VDE approved.

If redundant power is required, two PS 400C units can be mounted in each frame.

All output voltages from each supply are bussed to all card positions; selection between the supplies is made automatically on each board. AS 400 Dual Audio Crosspoint Board F7–023700–015 Each AS 400 receives 16 pairs of analog audio inputs from the chassis motherboard and switches them onto one of 32 pairs of output busses for processing by the Audio Output Board. A0 420 Dual Audio Output Board F7–023700–018 The AO 420 is a dual 16–channel output amplifier / buffer module with an on–board 16x1 monitor switcher that allows one of the output channel pairs to be selected onto an independent monitor bus.

The AO 420 also contains stereo mix circuitry for each output channel pair that provides, normal, swap, and mix functions independently on each output under control of the matrix control system.

The normal configuration mode of the Venus Audio matrix is dual channel –– one set of modules provides two independent channels for stereo or other multi–channel use. In this mode, the AO modules are used in pairs, each board providing output monitoring for one of the channels. If the AO board pairs are split, output monitoring for one of the channels will be lost. For this reason, Thomson recommends that audio switchers always carry pairs of AO boards. A0 430 Deluxe Audio Output Board F7–023700–054 The AO 430 is a special version of the audio output board that provides fully–floating outputs with high–current driver amplifiers.

This board offers exactly the same performance and functionality as the AO 420, plus the ability to drive up to 2,000 feet of 8451 type cable and to supply full signal levels into load terminations as low as 150 Ohms. The fully floating outputs provide the ability to deliver full output level to either balanced or unbalanced loads without the use of jumpers or gain adjustments.

Configuration guide 2−15 DUAL AUDIO CONFIGURATION BOARDS The Configuration Board (also known as the ZIF Board) connects the outputs of the Crosspoint Boards to the inputs of the Output Boards. These boards are made up of large high–density Zero Insertion Force (ZIF) connectors that mate with the signal pins on the top of each of the matrix boards. The number of these connectors on the board and the pattern by which they are connected determines the physical configuration of the matrix section. The following Dual Audio Configuration Boards are available: Size Part Number Cards: Slots Types 32x32 F7–023700–013 4 2 AS / 2 AO 64x32 F7–023700–012 6 4 AS / 2 AO 96x32 F7–023700–053 8 6 AS / 2 AO 160x32 F7–023700–011 12 10 AS / 4 AO 352x32 F7–023700–014 24 22 AS / 2 AO AP 400 Audio Rear Panels 01–043613–001 The Audio Rear Panel contains four rows of sixteen 3–terminal direct compression connectors and is used for connecting both inputs and outputs.

A 65th connector is provided for use by the output monitor bus as required. All Venus audio connections are balanced, using three wires , Gnd) for each input or output.

The connectors are wired via a PC assembly to four ribbon wire connectors, each of which carries sixteen of the signal lines. The Audio Rear Panel is 2.75” wide, filling 1/6 of the available mounting space at the rear of the chassis. One panel is required for each 64 signals into/out of the matrix. When planning connector requirements, always remember that audio connections are DUAL –– twice as many connections are on both inputs and outputs. AP 410 Audio Rear Panels 01–043930–001 The Dual Audio Configuration of the Venus gives a very high crosspoint density in the matrix but causes a real problem with external connections.

In some cases, it is not possible to locate enough terminal strips on the rear panel to accommodate all of the signals that can fit in the rack frame. The AP 410 panel uses high–density D–type connectors to increase the number of connections available at the rear panel.

Each AP 410 carries 8 of these connectors, each of which carries 24 balanced signal lines. These connectors are wired to 12 ribbon wire connectors in the standard 16–line configuration. This gives the AP 410 a total capacity of 192 lines, three times as many as the AP 400 in 1 1/2 times the amount of rear panel space. A prewired pigtail assembly (P/N 01–044728–003) is available which consists of the mating D– type connector and 24 ten foot lengths of 8451 cable attached to the connector pins. The other end of the cable is left bare for installation on–site to terminal blocks or patch bay equipment.

Configuration guide 2−16 AUDIO PATCH PANELS A prewired patch panel assembly using the AP 410 rear panels provides a convenient way to install the matrix and reduce wiring costs. This panel consists of a 48–loop bantam jackfield wired in a “half–normal” pattern. One row of the panel is wired to two AP 410 mating connectors and the other row is wired to a punch–block. In the input panel, the bottom row comes from the punch block and the top row goes to the matrix, while on the output panel this pattern is reversed. Stereo Input Panel 01–045123–001 Stereo Output Panel 01–045123–002 Mono Input Panel 01–045123–003 Mono Output Panel 01–045123–004 The standard length of both wiring bundles (from the punch–block to the patchfield and from the patchfield to the AP 410 connectors) is ten feet.

Other lengths are available.

Since each patch panel can handle 48 signal lines, and each D connector handles 24 lines, a total of four patch panels would be required for each AP 410 panel. Audio Input/Output Cables 01–043991–001 Ribbon wire assemblies carrying sixteen signal lines are used for all internal wiring of the audio signals in the Venus system. The I/O Cable can connect 16 inputs or outputs from the rear panel to the chassis motherboard. In most cases, these cables are used for outputs while the looping cable assemblies (below) are used for inputs. One kit is required for each 16 output lines from the matrix.

Audio Looping Cables 3 Position 01–044009–001 5 Position 01–044009–002 The Audio Looping Cables are used to bring the signals into the matrix from the rear panel and to provide input looping connections when connecting inputs from one matrix segment to another is necessary, either within a frame or between two frames.

Each Audio Looping Cable assembly consists of ribbon wire with either 3 or 5 connectors installed. The 3–position cable connects the rear panel and two matrix segments within a single rack frame, while the 5–position cable continues to two matrix segments in an adjacent rack frame.

One Looping cable assembly is required for each sixteen inputs; the size of the cable is determined by the pattern of matrix segments within the system.

Configuration guide 2−17 MONO AUDIO SYSTEMS It is possible to use the standard Dual Audio Venus hardware in mono mode by setting a jumper on the chassis motherboard that controls the operation of the AO 320 Output Boards. Configuring the mono switcher is exactly the same as for the Dual Audio switcher; each crosspoint board becomes a 32x32 block but each output card stays at 16 outputs. All Connectors and wiring are identical.

For purposes of comparison, the following table lists the Dual Audio and the Mono sizes for each of the Audio Configuration Boards: Dual Audio Size Mono Audio Size Cards: Slots Types 32x32 64x32 4 2 AS / 2 AO 64x32 128x32 6 4 AS / 2 AO 96x32 192x92 8 6 AS / 2 AO 160x32 320x32 12 10 AS / 2 AO 352x32 704x32 24 22 AS / 2 AO Audio Looping Cables AS 400 AO 420 AP 400 (2 sets of 4) AP 400 AO 420 Audio I/o Cables (2 sets of 4) AP 400 AP 400 64 x 64 Stereo Audio Matrix Signal Interconnect Wiring [Two 64 x 32 ZIF Boards] AS 400

Configuration guide 2−18 SERIAL DIGITAL VIDEO COMPONENTS RF 400 Chassis F7–023700–565 The Venus chassis provides the framework for the switcher’s uniquely flexible architecture. The chassis contains a motherboard which provides a connection plane between the matrix boards and the input/output wiring assemblies. Each chassis provides mounting locations for two power supplies and 24 matrix boards. The rear panel area of the chassis provides mounting locations for six standard rear panel assemblies and two option modules. The 32–output chassis (RF 400/32) is the standard model for most switcher configurations.

The motherboard in this model is designed to accept any combination of matrix cards and is used in building the majority of switchers where multiple matrix blocks are to be mounted in a single chassis. The 32–output chassis is used for all digital video switchers. PS 400C Power Supply F7–023700–137 Power for each RF 400 frame is provided by one PS 400C. This unit features automatic input voltage selection, making it usable on any line voltage standard. The PS 400C is VDE approved.

If redundant power is required, two PS 400C units can be mounted in each frame. All output voltages from each supply are bussed to all card positions; selection between the supplies is made automatically on each board. DS 401A Serial Digital Video Crosspoint Board F7–023700–067 Each DS 401A receives 16 serial digital video inputs at up to 400 Mbs from the chassis motherboard and switches them onto one of 32 output busses for processing by the Video Output Board. The DS 401A has automatic equalization for each input provides up to 24 dB of equalization, which is equivalent to about 750 feet of 8281 coax.

A data regeneration circuit is used to remove problems that can be caused by unusual DC content in certain test signals. Note: the DS 401A can be mixed with the DS 401B in the same chassis. D0 410 Serial Digital Video Output Board F7–023700–021 The DO 410 is a 16–channel output amplifier / buffer module with an on–board 16x1 monitor switcher that allows one of the output channels to be selected onto an independent monitor bus.

The DO 410 does not re–clock the signal at any point, passing the equalized and regenerated signal from the crosspoint card through with transition timing intact. SERIAL DIGITAL VIDEO CONFIGURATION BOARDS The Configuration Board (also known as the ZIF Board) connects the outputs of the Crosspoint Boards to the inputs of the Output Boards. These boards are made up of large high–density Zero Insertion Force (ZIF) connectors that mate with the signal pins on the top of each of the matrix boards. The number of these connectors on the board and the pattern by which they are connected determines the physical configuration of the matrix section.

The Serial Digital Video Configuration boards use balanced, terminated transmission lines to bus the output signals. The following Serial Digital Video Configuration Boards are available: Size Part Number Cards: Slots Types 32x32 F7–023700–033 4 2 DS / 2 DO 64x32 F7–023700–032 6 4 DS / 2 DO 64x64 F7–023700–030 12 8 DS / 4 DO 160x64 F7–023700–032 24 20 DS / 4 DO 352x32 F7–023700–031 24 22 DS / 2 DO VP 400A Video Rear Panels 01–044797–001 The Video Rear Panel contains 64 BNC connectors arranged in four rows of sixteen and is used for connecting both inputs and outputs. A 65th connector is provided for use by the output monitor bus as required.

The BNC connectors are wired via a PC assembly to eight multi–pin connectors, each of which carries eight signal lines. The Video Rear Panel is 2.75” wide, filling 1/6 of the available mounting space at the rear of the chassis.

Configuration guide 2−19 One panel is required for each 64 signals into/out of the matrix. Rear Panel Splitter 01–044086–001 Unlike analog video switchers, it is not possible to use passive looping techniques to connect multiple crosspoint cards onto a single input line in Serial Digital Video systems. Venus features a unique input distribution approach, which uses an impedance matched network to passively split the signal into an isolated feed for each crosspoint card. The losses caused by this splitting are restored in the input stage.

In all SDV switchers, each 32 inputs requires a rear panel splitter that divides the signal into two feeds.

This splitter mounts directly to the Video rear panel’s connector block. The input cables then connect the two feeds to the matrix splitters. Input All Resistors are 37.5 Ohm Input Cable Looping Cable To Crosspoint Boards –6 dB –18 dB –12 dB Input signal distribution for 32–output configurations Input All Resistors are 37.5 Ohm Input Cable To Crosspoint Boards –6 dB –18 dB –12 dB Input signal distribution for 64–output configurations Looping Cable ÁÁ ÁÁ ÁÁ ÁÁ Á Á Á Rear Panel Splitter Matrix Splitters ÁÁ Á Á Á Á ÁÁ ÁÁ ÁÁ ÁÁ ÁÁ Á ÁÁ Rear Panel Splitter Matrix Splitters ÁÁ Matrix Splitter 32–Output 01–044511–001 64–Output 01–044078–001 The matrix splitters are installed on the motherboard pins at the crosspoint card locations and provide a further division of the input signals.

The 32–Output version splits the signal into two equal feeds, one of which is then fed directly to the crosspoint card input, the other can be fed through a looping cable to a second crosspoint card. One splitter is required for each input cable.

The 64–output splitter works in the same way except that the signal is fed to two adjacent crosspoint cards directly from the splitter. This splitter also provides a connection for a looping cable to feed the signals to a second splitter, providing a total of four feeds on the single input line. Video Input Cables 22” Length 01–043988–001 26” Length 01–044390–001 36” Length 01–045713–001 Coaxial cables built with subminiature coax are used for all internal wiring of the video signals in the Venus system. The Input Cable connects the inputs from the rear panel splitter to the matrix splitter.

Each Video Input Cable kit consists of eight separate subminiature coax cables wired to a connector that mates with the rear panel splitter’s multi–pin connectors at one end and to the Matrix splitter’s connectors at the other end.

One cable assembly is required for each 8 input lines.

Configuration guide 2−20 Video Looping Cables 01–044796–001 The Video Looping Cables are used when connecting inputs from one matrix splitter to another is necessary, either within a frame or between two frames. Each Video Looping Cable assembly consists of eight coax cables terminated at both ends with a connector that mates with the splitters’ pins. One Looping cable assembly is required for each intermatrix connection of eight inputs. Video Output Cables 01–043990–001 Each Video Output Cable assembly consists of eight separate subminiature coax cables wired to a connector that mates with the Video Rear Panel’s multi–pin connectors at one end and to the chassis motherboard’s connectors at the other end.

One kit is required for each eight outputs from the matrix. DT 400 SDV Terminator Assembly 01–044074–001 The SDV Terminator is required in systems with less than a fully expanded input distribution network to maintain the proper network loading characteristics within the resistive splitting network. The terminator must be installed on any unused rear panel splitter feeds and on any unused looping feeds on the matrix splitters. The terminator uses the same connector block as the input and looping cable assemblies and is installed in the location on the splitters that would otherwise be occupied by the cable assemblies.

LARGE MATRIX INPUT DISTRIBUTION SYSTEM The standard resistive splitting system used in SDV Venus switchers is limited to a maximum of four matrix blocks, giving a maximum possible matrix size of 352x128 using 32–output blocks or 160x256 using 64–output blocks. In order to accommodate larger matrix sizes, a transformer splitter was developed to replace the 1x2 rear panel splitter with a 1x4 initial split, doubling the number of outputs that can be served by each input. The DV 423 Transformer Splitter assembly (F7–023700–063) is a 2RU rack–mounting panel that carries 20 individual transformer splitters.

Each of the splitters has one BNC connector for the input signal and four BNC connectors for the outputs. When this splitter is used, the rear panel splitters are not installed. The input signals are carried by BNC–BNC coax cables from the splitter outputs to VP 400A assemblies which are connected by input cable assemblies directly to the matrix splitters within the switcher chassis.

Configuration guide 2−21 RS 422 DATA MATRIX COMPONENTS RF 400 Chassis F7–023700–565 The Venus chassis provides the framework for the switcher’s uniquely flexible architecture. The chassis contains a motherboard that provides a connection plane between the matrix boards and the input/output wiring assemblies. Each chassis provides mounting locations for two power supplies and 24 matrix boards.

The rear panel area of the chassis provides mounting locations for six standard rear panel assemblies and two option modules. The 32–output chassis (RF 400/32) is the standard model for data switcher configurations. The motherboard in this model is designed to accept any combination of matrix cards and is used in building the majority of switchers where multiple matrix blocks are to be mounted in a single chassis.

PS 400C Power Supply F7–023700–137 Power for each RF 400 frame is provided by one PS 400C. This unit features automatic input voltage selection, making it usable on any line voltage standard. If redundant power is required, two PS 400C units can be mounted in each frame. All output voltages from each supply are bussed to all card positions; selection between the supplies is made automatically on each board. DM 400B Data Matrix Board F7–023700–129 The Venus Data Matrix is a port–oriented switcher. This means that rather than inputs and outputs, the switcher is laid out as a group of bidirectional data ports, each port is both an input to and an output from the switcher.

Each DM 400 receives 16 data inputs from the chassis motherboard, buffers them and places them onto an internal data bus. These input signals appear at each of 16 identical input selector switches on each DM 400 board in the system. The switch selects the signal that is to be fed to the associated transmit data line.

The DM 400B Data Matrix board allows software control of input/output pin functions, eliminating the need for crossover or Y–type cabling when connecting the switcher to external devices.

Configuration guide 2−22 DATA MATRIX CONFIGURATION BOARDS The Configuration Board (also known as the ZIF Board) connects the 16 receive data lines from each DM–400 board to all boards in the matrix. These boards are made up of large high–density Zero Insertion Force (ZIF) connectors that mate with the signal pins on the top of each of the matrix boards. The number of these connectors on the board and the pattern by which they are connected determines the physical configuration of the matrix section.

The following Data Matrix Configuration Boards are available: Size Part Number Cards: Slots Types 64 Ports F7–023700–037 4 4 DM 192 Ports F7–023700–038 12 12 DM DP 400 Data Rear Panels 01–045166–001 The DP 400 carries 32 Subminiature D–type connectors (Female Pins) arranged in four rows of eight. The connectors are wired via a PC assembly to four ribbon wire connectors, each of which carries sixteen of the signal lines. The Data Rear Panel is 2.75” wide, filling 1/6 of the available mounting space at the rear of the chassis. One panel is required for each 32 Ports of the matrix. When planning connector requirements, it is important to remember that the DP 400 provides only 32 ports in the same physical space in the frame that is occupied by a 64–port matrix block.

Be careful to allow sufficient rear panel space for the additional requirements of the DP 400 panel. DP 410 Audio Rear Panels 01–043930–001 The DP 410 panel uses high–density D–type connectors to increase the number of connections available at the rear panel for cases where the individual 9–pin connectors are not required or where the physical mounting space is not available to accommodate the 9–pin connector panels.

Each DP 410 carries 8 of these large connectors, each of which carries the signal lines for 12 ports. These connectors are connected via the input board described above to 12 ribbon wire connectors in the standard 16–line configuration. This gives the DP 410 a total capacity of 96 ports, three times as many as the DP 400 in 1 1/2 times the rear panel space. A prewired pigtail assembly (P/N 01–044728–003), consisting of the mating D– type connector and 24 ten foot lengths of 8451 cable attached to the connector pins, is available. The other end of the cable is left bare for installation on–site to terminal blocks or patch bay equipment.

Data Input/Output Cables 01–043991–001 Ribbon wire assemblies carry sixteen signal lines are used for all internal wiring of the data signals in the Venus system. The I/O Cable can connect 8 ports from the rear panel to the chassis motherboard.

Configuration guide 2−23 HIGH DEFINITION AND STANDARD DEFINITION VIDEO COMPONENTS RF 400 Chassis F7–023700–565 The Venus chassis provides the framework for the switcher’s uniquely flexible architecture. The chassis contains a motherboard, which provides a connection plane between the matrix boards and the input/output wiring assemblies.

Each chassis provides mounting locations for 2 power supplies and 24 matrix boards. The rear panel area of the chassis provides mounting locations for six standard rear panel assemblies and two option modules. PS 400C Power Supply F7–023700–137 Power for each RF 400 frame is provided by one PS 400C. This unit features automatic input voltage selection, making it usable for any line voltage standard. The PS 400C is VDE approved.

If redundant power is required, two PS 400C units can be mounted in each frame. All output voltages from each supply are bussed to all card positions, selection between the supplies is made automatically on each board. HE 416 (SD/HD Rear Panel) F7–023700–170 The HE 416 is a sixteen input equalizer board. It has 16 BNC inputs for use with HD–SDI or SDI signals. Four HE 416’s are included one rear panel. The inputs have adaptive equalizers for cable lengths up to 100 meters of Belden 1694A cable.

SE 416 (SD only Rear Panel) F7–023700–171 The SE 416 is similar to the HE 416 in all respects except for the equalizer ICs.

This board is used for SDI signals only, but functions for cable lengths up to 300 meters of Belden 1694 cable or 8281. Four SE 416’s are included in the rear panel. HD 408 F7–023700–172 The HD 408 cable driver has eight dual output drivers for HD–SDI signals. The main or upper output is non–inverting while the second output is inverted. Scrambled NRZI signals, such as SDI and HD–SDI, are not sensitive to polarity and will work fine with either output. DVB–ASI is polarity sensitive and will function properly only with the main output, unless the user provides inversion at the signal destination.

The output rise times of this board meet SMPTE 292M specifications. This board is powered by HO 411 board. The rear panel consists of four HD 408’s for a total of 32 outputs per rear panel.

PD 400 01–050980–001 The PD 400 board was designed to increase the efficiency of powering the equalizer boards. Each of the two DIN connectors for the PD 400 is powered by a separate set of power converters. Each half of the board is capable of powering at least six equalizer boards. Using the two DIN connectors in a redundant operation mode is possible, but removal of the board to replace a faulty section would result in a loss of power. The normal mode of operation is to use two PD 400 boards in a redundant mode where removal of one board leaves the equalizers fully powered by the other board.

The redundancy diodes are installed in the outputs of this board, with the normal interconnection for redundancy a result of connecting two sections to the parallel connected connectors on the equalizer boards. The board operates on the ±22–volt supplies from the PS 400 power supply to make the output voltages. It uses a small amount of the +7 volt supply to operate the alarm circuitry.

HV 421 Splitter Board 01–050975–001 The 1X2 splitter allows one feed from the equalizer boards to feed two adjacent matrix boards. This doubles the maximum number of matrix boards that can be fed from the equalizer board, and expands the output capacity of the system from 128 outputs to 256 outputs. This splitter is useful only in systems that are for 64 output increments where two adjacent matrix boards receive the same input signals. This board does not terminate the signal lines that it splits. The matrix boards provide the load termination for the input signals. Proper operation of the system requires that both matrix boards be installed to the splitter outputs, or a loader board must be installed to substitute for a missing matrix board.

Configuration guide 2−24 HL 432 Loader Board F7–023700–174 The HL 432 Loader Board is used to terminate the splitter outputs if no matrix board is installed. This board is passive and consumes no power. It contains two DIN connectors to mate with the motherboard and is the same size as a matrix board. The HL 432 slides through the ZIF connectors on the ZIF board, but it does not have any gold fingers to make contact with the ZIF connector. The ZIF connector should still be closed after the board is installed to allow the front door of the rack frame to close. This board consists of the above mentioned board and connectors with 32 resistors to terminate the signals.

HS 400 F7–023700–160 The HS 400 is a 32X32 matrix board for signals up to 1.5 Gbits/sec. Its outputs are low impedance, current driven into the ZIF board. The signals are DC coupled through the matrix board. The board is controlled by Venus crosspoint bus in essentially the same manner as all standard Venus matrix boards. One HS 400 makes up 32 inputs per 32 output block. HO 411 F7–023700–167 The HO 411 reclocking output board receives signals from the ZIF board and processes them to feed the cable driver boards. The board has reclockers that function only for HD–SDI signals at 1.485 Gbits/sec.

The reclockers must be switched off for other data rates. The reclockers are individually switched on and off by front mounted piano style dip switches. Placing the switch in the on (down or depressed) position turns reclocking on. One HO 411 makes up 32 outputs.

ZIF BOARDS Three versions of ZIF boards are being designed for the first phase of the product. Additional ZIF boards will be added in the future. 64X64 F7–023700–177 The 64X64 ZIF board has 8 card slots and can accommodate a maximum of four matrix boards and two output boards. In most applications, using two or more of the matrix board slots for PD 400 boards will be necessary. 160X64 F7–023700–164 The 160X64 ZIF board has 12 card slots and accommodates a maximum of 10 matrix boards and two output boards. In most applications, use of two of the matrix board slots for PD 400 boards will be necessary, reducing this to a 128X64 application.

Two of these ZIF boards may be mounted in a single Venus frame, allowing a 128X128 switcher to be constructed.

This ZIF will also allow for smaller configurations by simply leaving out matrix and output boards. A full 160X64 can be constructed by placing the PD 400 boards in another section of the same rack frame or in a different rack frame. 352X64 F7–023700–163 The 352X64 ZIF board has 24 card slots and can accommodate a maximum of 22 matrix boards and two output boards. In most applications using two or more of the matrix board slots for PD 400 boards will be necessary, limiting it to a 320X64 application or smaller.

INTERNAL CABLING Several types of internal cables are used to connect between the rear panels and the motherboard.

Equalizer Power Cabling 01–051393–001 The equalizer power cable assembly feeds power from the PD 400 board to the equalizers. The DIN connector plugs into the motherboard and the power connectors plug into the equalizer boards. Two interconnected power sockets are provided on the equalizer boards. Redundant operation is provided by connecting a separate power feed from either the other side of the same PD 400 board for single board redundancy, or from a second PD 400 board for dual board redundancy. System designers and installers should be careful not to interconnect more than two PD 400 feeds.

This means all equalizers that receive a power feed from one section of a PD 400 board should receive their redundant power feed from a common section of the redundant PD 400, otherwise three or more PD sections may become connected in parallel.

Configuration guide 2−25 Unused power connectors should be bagged, sleeved, or otherwise protected to prevent shorting the power to ground or other signals.

Two of these cable assemblies are needed for each HO 411. One DIN connector from the motherboard is cabled to two DIN connectors, one for each of two HD 408 boards. Two power cables and connectors are also provided, one for each HD 408. The signals are cabled using shielded differential pair cable. The shields are grounded at the cable driver end and left floating at the two–row connector, which connects to the motherboard. The power connections are made using two wires twisted together INPUT CABLING SYSTEMS The input cabling system is more complicated with many combinations of cabling that may be required.

The interconnecting cable is a differential signal pair with a shield. At this time, the shield is connected to ground at the equalizer end, with the other end floating. The Equalizer boards have two DIN connectors that have eight signals in each connector, for 16 signals from the equalizer board. Four separate feeds are provided for each of the eight signals, thus using up all of the connector pins in the two DIN connectors. Thus, two cable assemblies are needed to connect two equalizer boards, and their associated 32 signals, to one or more matrix boards. Two equalizer boards must be connected to each matrix board, either directly or through a 1X2 splitter installed on the back of the motherboard.

The length of the cables between the equalizer connectors and the motherboard connectors depends upon the location of the matrix boards relative to the equalizer boards. The cable assemblies are described by two terms. The first term describes the number of equalizer and matrix connectors. Thus, a “2X1” cable assembly has two equalizer connectors and one matrix connector. The second term describes the approximate length of the interconnecting cables, and infers the number of matrix connectors. A “0” indicates no cable, a “1” indicates a cable for connecting within the same rack frame, a “2” indicates a cable for connecting to an adjacent rack frame, a “3” indicates a cable length for connecting to a rack frame two away, and a “4” indicates a cable length suitable for connecting to a rack frame three away with two rack frames between.

Thus, a 1–2–2–0 indicates an assembly with three cable groups, one for connection within the rack frame and two for connection to adjacent rack frames. Since other rack frames may be located either above or below the rack frame with the equalizers, cable bundling and tie wraps will need to be adjusted when the cable assemblies are installed within the system.

These kits will consist of 2 row DIN connectors with 16 cables installed. The other ends of the cables will then be plugged into the equalizer end of the cable assemblies already in use.

These expansion kits will come in four lengths, 1, 2, 3, and 4, corresponding to the second term in the cable assembly designations.

Configuration guide 2−30 320x256 With Spread Inputs This configuration spreads the inputs across all four rack frames. The bottom frame has two input rear panels, and the other three each have one input panel. This option minimizes the loss of inputs if power fails within one rack frame. It would also be possible to use special power cables for the equalizers that would allow equalizers to be powered from two separate rack frames. This could reduce the number of PD–400s to 4 while still giving full redundancy. 320X256 WITH FULLY SPREAD INPUTS AND REDUNDANCY Rack frame with power supply and motherboard 4 352X64 ZIF Board 4 Input rear panels with 4 equalizers in each panel 5 PD 400 boards to power equalizers 4 (redundant to adjacent frame) Output rear panels with 4 cable drivers in each 8 HS 400 32X32 Matrix boards 80 HO 411 32 Output Reclocker board 8 1X2 Input Splitter 80 HL 432 Loader Board 0 Equalizer Power Cable Assemblies 16 2X4 Input Cable Assemblies 1–2–3–4 12 2X4 Input Cable Assemblies 1–2–2–3 8 Output Cable Assemblies 16

Configuration guide 2−31 ES 401 SYNCHRONOUS/ASYNCHRONOUS AES DIGITAL AUDIO COMPONENTS In the ES 401§ synchronous / asynchronous digital audio router, synchronous inputs are automatically timed to the reference signal, while simultaneously asynchronous inputs are passed through the router undisturbed. Sync detectors used on the inputs retransmit the asynchronous signals using clocks derived from the incoming signal. This unique feature introduces unsurpassed flexibility in audio routing while eliminating many potential pitfalls of conventional synchronous routers, by allowing the routing of “free running” asynchronous sources or audio data at different data rates within the same infrastructure.

The ES 401 audio output cards offer a denser package of 32 outputs per board, along with buffering and re–encoding of the signals. Several new features are also enabled by this new technology. In the Venus 2001 audio router, the AES signals arrive and leave the router as AES pairs, but are handled internally as individual signals. Three different crosspoint mappings allow the following modes of operation under Jupiter control. Single Level Stereo: All routing is done as pairs. Two–Level Stereo: This feature brings to the digital domain the flexibility offered by traditional analog routers.

Allowing the ability to separate the left and right channels within each AES bit stream and to swap and mix any right channel with any left channel.

Single Level Mono: Each individual channel signal is separately routed; the outputs are re–assembled into a two–channel AES bit stream. In addition, the new AES basic output card provides significant decrease in transition noise. As an option, the user can choose the Deluxe output card that offers a “soft transition” of the output signal to virtually eliminate the clicks and pops normally associated with audio switching; it is much like a V–fade transition used in the master control switchers. This feature enables the customers to perform high quality on–air switching without the need for additional complex and expensive audio processing.

Note: ES 401 series synchronous / asynchronous digital audio boards and associated components are incompatible with the original “ES–400” series asynchronous (non–reclocking) digital audio boards and associated components. “Associated components” include configuration (ZIF) connectors, mother boards, ribbon connectors, sync reference modules, rear panels, etc. RF 400 Chassis F7–023700–565 The Venus chassis provides the framework for the switcher’s uniquely flexible architecture. The chassis contains a motherboard, which provides a connection plane between the matrix boards and the input/output wiring assemblies.

Each chassis provides mounting locations for 2 power supplies and 24 matrix boards. The rear panel area of the chassis provides mounting locations for six standard rear panel assemblies and two option modules. The 32–output chassis (RF 400/32) is the standard model for digital audio switcher configurations. The motherboard in this model is designed to accept any combination of matrix cards and is used in building the majority of switchers where multiple matrix blocks are to be mounted in a single chassis.

PS 400C Power Supply F7–023700–137 Power for each RF 400 frame is provided by one PS 400C. This unit features automatic input voltage selection, making it usable for any line voltage standard. The PS 400C is VDE approved. If redundant power is required, two PS 400C units can be mounted in each frame. All output voltages from each supply are bussed to all card positions, selection between the supplies is made automatically on each board. ES 401 Matrix Card F7–023700–150 The ES 401 32x32 matrix card provides switching internally as 64 x 64 instead of 32 x 32 as in present Venus product. Incoming signals are “disassembled” into individual channels.

Sync detectors on each input, determine lock to reference and pass clocks accordingly. If a signal is synchronous to the reference, it is re–phased to align the sample boundaries with those of the reference signal. Asynchronous signals can be passed through router simultaneously to that of the synchronous signals. If the signal is not synchronous with the reference, it is passed “async” with no re–phasing. § In this manual, “ES 401 switcher” refers to the AES11 synchronous/asynchronous version of the digital audio switcher matrix board and associated components.

Configuration guide 2−32 EO 421 Basic Output Card F7–023700–151 The EO 421 thirty–two channel output card provides basic buffering and re–encoding of AES pairs and stereo manipulation functions “ Swap/Mix/Left Only/Right Only” for synchronous signals for 32 outputs. Reference clock generator feeds all matrix cards on a given ZIF motherboard. EO 431 Deluxe Output Card F7–023700–152 The EO 431 provides the same basic functions as the EO 421. On–board hardware provides soft “V–fade” at switch point for truly clickless switching of synchronous signals and re–encoding to AES pairs for 32 outputs.

The reference clock generator feeds all matrix cards on a given ZIF motherboard.

EP 421 Rear Panel F7–023700–153 The EP 421 Rear Panel contains 64 BNC connectors arranged in four rows of sixteen and is used for connecting both inputs and outputs. A 65th connector is provided for use by the output monitor bus as required. The connectors are wired via the input PC assembly described above to four ribbon wire connectors, each of which carries sixteen of the signal lines. The BNC Rear Panel is 2.75” wide, filling 1/6 of the available mounting space at the rear of the chassis. One panel is required for each 64 signals into/out of the matrix.

ER 421 AES Sync Reference Module F7–023700–152 The sync reference card is required on all systems to maintain synchronous operation and to run different sample rates.

It also provides video–based references and switching. ET 401 AES Terminator Module 01–050633–001 In an AES switcher, each of the Looping cables must be fitted with a terminator assembly that is piggybacked onto the cable at the last connector position. Audio Input/Output Cables 01–043991–001 Ribbon wire assemblies, which carry sixteen signal lines, are used for all internal wiring of the audio signals in the Venus system. The I/O Cable can connect 16 inputs or outputs from the rear panel to the chassis motherboard. In most cases, these cables are used for outputs while the looping cable assemblies (below) are used for inputs.

One kit is required for each 16–output lines from the matrix.

Audio Looping Cables 3 POSITION 01–044009–001 5 POSITION 01–044009–002 The Audio Looping Cables are used to bring the signals into the matrix from the rear panel and to provide input looping connections when connecting inputs from one matrix segment to another is necessary, either within a frame or between two frames. Each Audio Looping Cable assembly consists of ribbon wire with either 3 or 5 connectors installed. The 3–position cable connects the rear panel and two matrix segments within a single rack frame, while the 5–position cable continues with two matrix segments in an adjacent rack frame.

One Looping Cable assembly is required for each sixteen inputs. The size of the cable is determined by the pattern of matrix segments within the system. DIGITAL AUDIO CONFIGURATION BOARDS (ZIF) The Configuration Board (also known as the ZIF Board) connects the outputs of the Crosspoint Boards to the inputs of the Output Boards. These boards are made up of large high–density Zero Insertion Force (ZIF) connectors that mate with the signal pins on the top of each of the matrix boards. The number of these connectors on the board and the pattern by which they are connected determines the physical configuration of the matrix section.

Configuration guide 2−35 DC POWER OPTION (RF 402D) Optional Chassis Assemblies and Power Supply Modules are available for Venus digital routing switchers to allow the switchers to be powered from –48 VDC or –24 VDC power systems. This allows the switchers to be configured for direct connection to the battery supplies found in telecom exchange and remote station locations. The DC version of the Venus chassis will accept one or two power supply modules to provide full hot–swappable redundancy. Two independent DC power connections are provided at the rear of the chassis to allow the switcher to be connected to independent power systems for additional protection.

System specifications for DC–powered switchers are identical to the normal mains–powered versions for all environmental, physical, and performance characteristics, including system power requirement calculations. Power connectors provided on the DC versions of the switcher chassis are large–diameter binding posts (see page 3–8). To order a router for DC–powered operation, use the following part numbers: RF 402D F7–023800–024 Chassis Select one (two for redundancy) of the following: PS 400D48 F7–023800–002 for 48 VDC systems PS 400D24 F7–023800–018 for 24 VDC systems
