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 RT-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 input connections are also located on the back of the unit. A BNC connector is provided
for each channel. The video inputs are connected to an appropriate 75
Ω baseband video
source such as a camera or a video recorder output. For optimum performance the video cables
should be the shortest length of coax practical.
