Figure 51. CM9760-RPL Rear Panel Looping Card
As illustrated in Figure 51, the CM9760-RPL card includes the following:
• BNC Connectors (16 pairs): Provide the physical connection point for coaxial cable. For each pair of BNC connectors, one connector
connects to a video source and the other connector connects to the video output device to which the video is looped.
• Termination Jumpers JP1-JP16: Determine whether video is to be terminated (jumper positions 1 and 2) or unterminated (jumper positions
2 and 3):
– When looping functions are required, the termination jumpers must be set in the unterminated position.
– When looping functions are not required, the jumpers must be set in the terminated position.
The jumpers are set in the appropriate position when your system is configured at the factory. However, if you change your system—for
example, add or replace a card—you may need to change the termination.
• Downframe Connector: Sixteen-pin connector that connects to a downframed bay by means of a downframe cable.
CM9760-RPL Card Guidelines
The following guidelines apply to the CM9760-RPL card:
• The CM9760-RPL card connects to a CM9760-VCC video input card, which is installed into the front of the matrix bay.
• The CM9760-RPL card must be installed before the associated CM9760-VCC video input card is installed into the front of the matrix bay.
• In a bay that is to be fully populated with CM9760-RPL cards, note the following:
– The cards must be installed into odd slot positions only. The corresponding CM9760-VCC cards must also occupy odd slot positions.
– The maximum number of video inputs in a matrix bay that is fully populated with CM9760-RPL cards is 128.
• When installing a new card, termination jumpers must be set in the proper position: terminated or unterminated.
