Downframing | Pelco 9770 specification

Downframing

To expand the matrix video outputs beyond 32, you can downframe the video from the first CM9770-MXB to subsequent CM9770-MXB units for an additional 32 monitor outputs on each matrix bay. Refer to Figure 31.

You can connect a maximum of eight bays in a downframing configuration for a total MXB capacity of 256 monitors; in addition, you can increase monitor capacity further by using MDA units, for a total single-node system capacity of 512 monitors.

When downframing video, the termination jumpers on the RPC cards in the first bay must be set in the unterminated position. Refer to Change the Termination Jumpers on a Rear Panel Video BNC Cardin the Installation section for instructions.

When looping video out to another device (such as a DVR, VCR, or switcher), use the CM9770-DFL card in the final bay. You must set the termination jumpers on the CM9770-DFL card to the unterminated position. Refer to the Change the Termination Jumpers on a Rear Panel Video BNC Card section. Terminate the video signal at the final device.
