Pelco Video Input/Output Connections, Opening the CM9770-MXB Front Cover, Installation Tips

VIDEO INPUT/OUTPUT CONNECTIONS

The following steps provide an overview of how to connect video input and output sources. More complete procedures are provided in the subsequent sections.

NOTE: If your System 9770 is configured by Pelco, the appropriate number of video input cards and monitor output cards and BNC rear panels are installed at the factory, and steps 1 and 2 are not necessary. If this is the case, skip to Step 3.

1.Install the CM9770-VCC and CM9770-VMC cards in the matrix bay. Refer to the Installing Video Input Cards (CM9770-VCC)section and the Installing Monitor Output Cards (CM9770-VMC)section in the following pages.

2.Slide the CM9770-RPC and CM9770-RPM BNC rear panels into the appropriate slots from the back of the matrix bay. Refer to the Insert or Replace a Rear Panel Video BNC Card (CM9770-RPC)section and the Insert or Replace a Rear Panel Monitor BNC Card (CM9770-RPM)section in the following pages.

3.Before you connect any video input or output to the matrix bay, you may want to power up the unit to ensure that the system is operating properly. Refer to the Performing a Basic LED Check section.

4.Connect video inputs and monitor outputs to the rear panel BNC connectors on the CM9770-MXB matrix bay unit(s).

Installation Tips

•Be sure each connection is secure. For best results, use crimp-on BNCs only. Do not use screw-on BNCs; these typically do not provide adequate ground and signal connections.

•Label each video input; this can save a considerable amount of troubleshooting time in the future.

•Video output from the CM9770-VMC cards is not terminated. Terminate the video signal at the output device (monitor or VCR). If you are looping to other devices, unterminate all but the last device.

NOTE: The end point of any video cable run must be terminated in 75 ohms.

Opening the CM9770-MXB Front Cover

To install or remove a video input card, monitor output card, or power supply, you must first open the CM9770-MXB front cover.

1.Loosen the two screws at the top of the CM9770-MXB frame.

2.Pull the front cover towards you. The hinges at the bottom keep the cover attached to the frame.

3.When you are finished working with the interior components, close the cover and tighten the screws at the top of the frame.

NOTE: Although the CM9770-MXB will function properly with the front cover open, the front cover must remain closed during system operation to meet safety standards.
