VIDEO INPUT / OUTPUT CONNECTIONS
Video input and output connections are located on the rear of the 980 series units. 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. 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.
The location of a video input to the RT-91685SL will be mirrored as a video output at the RR-
91685SL. For example, the Channel 2 video input on the RT-980-1530 will become the Channel
2 video output on the RR-980-1530 after traveling across the fiber infrastructure.
RT-91685SL DATA INPUT / OUTPUT CONNECTIONS
Data input and output connections are made via terminal blocks on the back of the RT-482-
1470/1490 unit. See the drawings below for proper orientation of the input and output
connections for each of the two data channels. Please note that the far right pin on each
connection drawing corresponds with the far right terminal block pin on the unit.

Data input and output connections are made via terminal blocks on the back of the RR-482-
1470/1490 unit. See the drawings on the next page for proper orientation of the input and output
connections for each of the two data channels. Please note that the far right pin on each
connection drawing corresponds with the far right terminal block pin on the unit.
TYPICAL SYSTEM DATA CONNECTIONS
System data connections are based on industry standard EIA terminology for the transmission
of electronic data signals. Using this terminology, the driver of an electronic signal is labeled TX
or data out. Correspondingly, the receiver of an electronic signal is labeled RX or data in. The
plus terminal of the copper device is connected to the plus terminal of the fiber modem and the
minus is connected to the minus. Not all manufactures follow standard EIA terminology. Consult
the installation instructions for your copper device if you are unsure which two wires are the
drive (data out) wires and which two wires are the receive (data in) wires.
Please note that Data In on the RT-91685SL becomes Data Out on the RR-91685SL after going
across the fiber. The reverse flow follows the same orientation.
