Pelco System 9760 manual Installing or Replacing a CM9760-RPL Rear Panel Looping Card

INSTALLING OR REPLACING A CM9760-RPL REAR PANEL LOOPING CARD

The CM9760-RPL rear panel looping card contains two rows of BNC connectors and therefore occupies two slot positions in the matrix bay. The CM9760-RPL card connects to one CM9760-VCC video input card, which is installed into the front of the matrix bay. Up to eight CM9760-RPL cards can be installed when a maximum of 128 video inputs is required in a system that also requires looping. If necessary, a CM9760-RPL card can be replaced. To install or replace a CM9760-RPL card, refer to the sections that follow.

Installing a CM9760-RPL Card

WARNINGS:

•Rear panel card installation should be performed by qualified personnel only.

•Electrostatic discharge (ESD) precautions must be observed when installing a rear panel card. Always wear a grounding strap con- nected to an approved grounding source when working on or near exposed electronic equipment.

NOTE: A CM9760-RPL card must be installed before the associated CM9760-VCC video input card is installed.

To install a CM9760-RPL card, do the following:

1.Set termination jumpers JP1-JP16 (refer to Figure 20) in the proper position:

•When looping functions are required, set the jumpers in the unterminated position (positions 2 and 3).

•When looping functions are not required, set the jumpers in the terminated position (positions 1 and 2).

2.Locate the desired slot position at the rear of the bay.

NOTE: In a bay that is to be fully populated with CM9760-RPL cards, each card must be installed into an odd slot position only.

The corresponding CM9760-VCC cards must also occupy odd slot positions.
