                                  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.

Configuration guide


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

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                            Power Supply             Power Supply

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


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.

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

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.
VL 400 Video Bus Loader                                                       01–044053–001

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.

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.

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:

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.

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.

                  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

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.

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:

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 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.

One panel is required for each 64 signals into/out of the matrix.

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.

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.

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.

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.

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.

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.

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.
