The 8485 Series, designed for Panasonic Security System prod-
ucts, transmits four channels of high-quality video with switch
selectable bi-directional RS485 data or bi-directional RS422 and
RS232 on a single multimode optical fiber. Included in the circuit
design is a switch selectable 2 or 4 wire configuration and the abil-
ity to select data line termination. Designed to be completely
transparent to all camera and monitor manufacturers, this system
requires no field adjustments at installation or additional mainte-
nance thereafter. Diagnostic indicators provide a quick visual
indication of system status. In addition, two sub-carriers can be
added to each video channel using the 500 Series modulators and
demodulators. Equipment may be mounted as stand alone mod-
ules or rack units by the position of the mounting brackets.
