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

1. Install the CM9780-VCC and CM9780-VMC cards in the matrix bay. Refer to the 

 

 

 section in the following pages.

2. Slide the CM9780-DFC and CM9780-RPM BNC rear panels into the appropriate slots from the back of the matrix bay. Refer to the 

 

 

3. Before you connect any video input or output to the matrix bay, you may want to power up the unit to make sure that the system is 

operating properly. Refer to the 

 

 section.

4. Connect video inputs to the VPP panels, and then connect the DFC cables between the VPP panels and the MXB. 

5. Connect monitor outputs to the rear panel BNC connectors (RPM) on the MXB.

 

•

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 CM9780-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.

 

To install or remove a video input card, monitor output card, or power supply, you must first open the CM9780-MXB front cover.

1. Loosen the two screws at the top of the CM9780-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.

 

 If your System 9780 is configured by Pelco, the appropriate number of video input cards and monitor output cards and BNC and DFC 

rear panels are installed at the factory, and steps 1 and 2 are not necessary. If this is the case, skip to Step 3.

 

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

 

  Although the CM9780-MXB will function properly with the front cover open, the front cover must remain closed during system 

operation for the unit to meet safety standards.
