NOTE: Remember that the first few RS-422 COM ports on the CC1 must be used for one or more matrix bays and any network interface units
and hot switch units. For more information on using RS-422 COM ports, refer to the matrix system port assignment table and the Installation/
Operation manual for your specific matrix system.

MATRIX BAY CONNECTION
Use a coaxial cable to connect the Video Out connector on the rear panel of the CM9700MDD-EVS to the matrix bay. Refer to Table A for
maximum video coaxial cable distances.
1. Connect the coaxial cable to the video out connector on the CM9700MDD-EVS.
2. Connect the coaxial cable to any available matrix bay video input connector as appropriate for your system:
• In a System 9760, video input connectors are on the CM9760-MXB rear panel, as shown in Figure 13
• In a System 9770, video input connectors are on the CM9770-MXB rear panel, as shown in Figure 14.
• In a System 9780, video input connectors are on the CM9700-VPP panel, as shown in Figure 15.
NOTE: The distance from the CM9700MDD-EVS to the matrix bay video input connector must be less than the maximum distance for the coaxial
cable. Refer to Table B for maximum video coaxial cable distances.
Table B. Video Coaxial Cable Requirements
*Cable requirements:
• 75-ohm impedance.
• All-copper center conductor; steel-center conductor cable may result in poor performance.
• All-copper braided shield with 95% braid coverage.
