FIBER CONNECTION
The fiber optic connection is made via a FC/PC connector located on the right side of the unit.
VIDEO INPUT CONNECTION
The video input connection is made via a BNC connector on the right side of the unit. The video input should be
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.
DATA INPUT / OUTPUT CONNECTIONS
Data input and output connections are made via a terminal block on the right side of the unit. See the label on
the unit for proper orientation of input and output connections.
TYPICAL RS422 DATA CONNECTIONS
RS422 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 MT-3340-12VDC becomes Data Out on the RR-3340 after going across the
fiber. The reverse flow follows the same orientation.
