Transmitter
The American Fibertek 8489 Series transmits four channels of high-quality
video with switch selectable bi-directional RS485 data or bi-directional RS422
and Contact Closure on a multimode optical fiber. Included in the circuit
design is a switch selectable 2 or 4 wire configuration and the ability 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 maintenance 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 modules or rack
units by the position of the mounting brackets.
