Installation
Installation in frame or chassis:
See details in separate manual for selected frame type.
Before installing in frame, make any required link changes as detailed in the Configuration section.
AVS-3010 & AVS-3011: Analogue Video Connections:
If input termination is required then 75 Ω termination BNC plugs should be fitted to the loop through input sockets.
AAS-3020 & AAS-3021: Audio Connections:
If input termination is required then termination resistors should be fitted to the input sockets.
Follow the polarity markings on the rear assembly or incorrect phasing will result.
DDS-3030 & DDS-3031: RS422 / RS485 Data Connections:
If a change in the input termination is required, consult the configuration section for details.
Follow the connection markings on the rear assembly carefully or incorrect operation will result.
As this switcher is bi-directional, extreme care must be taken in its application for configurations greater than 5 x 1
or conflicts will result.
DVS-3040 & DVS-3041: Digital Video Connections:
Input termination is fitted and should not be altered. No loop through facility is available. For applications requiring
multiple destinations, a distribution amplifier such as the DVA-3002 should be used.
CPS-3050 -- Local control:
All switchers are sold with a plain front panel with DC power LED and printed with the switcher type number and
IRT logo. The CPS-3050 provides the necessary components to add control buttons and tally to the front panel.
Before fitting the CPS-3050, the original front panel and LD 1, LED DC indicator, must be removed.
The CPS-3050 PCB should then be pressed carefully into place making sure that the pins on the CPS-3050 plug
mate correctly with the socket on the main module PCB.
The front plate is then fitted using the screws and spacers provided.
For local switching, to take effect link LK 3 must be placed in the “A” position. See Configuration for details.
TPS-3010 -- Local tally panel:
All switchers are sold with a plain front panel with DC power LED and printed with the switcher type number and
IRT logo.
The TPS-3010 provides the necessary components to add tally LED indicators to the front panel. This is desirable
when switchers are controlled only by remote connections that are distant from the switcher. This panel is especially
useful when switchers are controlled via the CDC-3060 controller from a remote location using RS232 connections.
The TPS-3010 provides confidence that a slave switcher has responded to the master command and can therefore
greatly assist in finding faults in inter-module wiring.
Before fitting the TPS-3010, the original front panel and LD 1, LED DC indicator, must be removed.
The TPS-3010 PCB should then be pressed carefully into place making sure that the pins on the TPS-3010 plug
mate correctly with the socket on the main module PCB.
The front plate is then fitted using the screws and spacers provided.
