3
The unit slides into any two adjacent open slots in the SR-20 subrack. Use a small screwdriver
to push and lock the four ¼ turn fasteners into place.
POWER SOURCE
Power to the unit is supplied by the subrack. Please refer to the SR-20 and PSR instructions for
further details.
POWER CONNECTION
Power is supplied to the unit via a four finger backplane connector. The RR-404C can be
inserted into the subrack or removed from the subrack with power applied to the backplane.
INPUT / OUTPUT CONNECTIONS
The fiber optic connection is made via a ST connector located on the back of the unit. Be sure
to allow sufficient room for the required minimum bend radius of the fiber cable used.
Video output connections are also located on the back of the unit. A BNC connector is provided
for each channel. The 75
Ω video outputs can be looped through typical baseband video inputs
of switchers, recorders and other equipment as required. For proper operation, the outputs must
be terminated with 75
Ω. For optimum performance the video cables should be the shortest
length of coax practical.
