96 C1572M (9/05)
As illustrated in Figure 50, the CM9760-RPC card includes the following:
• BNC Connectors (16): Provide the physical connection point for coaxial cable
• Termination Jumpers JP1-JP16: Determine whether video is to be terminated (jumper positions 1 and 2) or unterminated (jumper
positions 2 and 3):
– In a single-bay configuration (up to 256 cameras and 16 monitors), the setting of the jumpers depends on whether video is to be looped
to another device (for example, a DVR, VCR, or matrix switcher):
• When looping is not required, the jumpers must be set in the terminated position (default position).
• When looping is required, the jumpers must be set in the unterminated position.
– In multiple-bay configurations, the jumpers must be set in the unterminated 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-RPC Card Guidelines
The following guidelines apply to the CM9760-RPC card:
• The CM9760-RPC card connects to a CM9760-VCC video input card, which is installed into the front of the matrix bay. Up to 16 CM9760-
RPC cards can be inserted into 16 possible slot positions that are associated with the slot positions of the corresponding CM9760-VCC
cards.
• The CM9760-RPC card must be installed before the associated CM9760-VCC video input card is installed into the front of the matrix bay.
• When installing a new card, termination jumpers must be set in the proper position: terminated or unterminated.
CM9760-RPL REAR PANEL LOOPING CARD
The CM9760-RPL rear panel looping card (refer to Figure 51) allows the looping of video. The card contains 16 pairs of BNC connectors that loop
video from video input sources such as cameras to video output devices such as DVRs, VCRs, and matrix switchers. Because of the two rows of
BNC connectors, the CM9760-RPL card requires two slot positions in the matrix bay. The CM9760-RPL card connects to one CM9760-VCC video
input card.
When a maximum of 128 video inputs is required in a system that also requires looping, up to eight CM9760-RPL cards can be used in a
CM9760-MXB.
