Camera Port Termination Jumpers

The MVS-8100C uses eight 2-pin headers to select between 75 Ohm or high impedance

termination of the video input lines. An uncovered jumper block provides a

high-impedance input. To terminate a video input port with a 75-Ohm resistor, cover the

jumper block in the positions shown in Table 16.

The MVS-8100C ships with 75 Ohm termination selected for all video input lines (all

termination jumpers are installed). This setting is correct for the majority of installations.

Light Ports

The MVS-8100C uses one or two 8-pin DIN connectors for the connection of light

modules, as described in Installing Light Control Hardware on page 25.

The light port on the MVS-8100C’s back panel breaks out into light ports 0 and 1,

corresponding to camera ports 0 and 1. The light port on the camera port Expansion

panel breaks into light ports 2 and 3.
