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.

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.

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.
