VIDEO OUTPUT CONNECTION

The video output connection is made via a BNC connector on the right side of the unit. The 75Ω video

output can be looped through typical baseband video inputs of switchers, recorders and other

equipment as required. For proper operation, the output must be terminated with 75Ω. For optimum

performance the video cables should be the shortest length of coax practical.

FIBER CONNECTION

The fiber optic connection is made via a ST connector located on the right side of the unit.

SENSORNET INPUT / OUTPUT CONNECTIONS

Data input and output connections are made via a terminal block on the right side of the unit. Follow

the label on the MRM-61 for proper orientation of Sensornet data input/output wires.

DATA TERMINATION REQUIRMENTS

The MRM-61 is shipped from the factory with internal data input/output 120 ohm termination

switched on. In order to remove the internal termination, the unit needs to be opened up and

switch setting #2 needs to be modified using the internal switch/jumper settings shown below.

There are several other switches on the same switch bank with the data termination switch.

These switches must not be changed. The drawing below indicates their original

positions.

To open the MRM-61, remove the screw on the bottom of the module. Also remove two screws holding

the end panel to the chassis on the side with the video and data connections. Slide PCB assembly out

of chassis to access the switch and jumper locations.
