INSTALLATION AND OPERATION MANUAL
FDX50M2, FDX51M2
RS232/422 POINT-TO-POINT DATA TRANSCEIVER
The ComNet™ FDX50M2 and FDX51M2 data transceivers are interchangeable
by application and provide point-to-point transmission of simplex or duplex EIA
RS232/RS422 data signals over two multimode optical fibers. The transceivers are
transparent to data encoding allowing for broad-range compatibility.
Each transceiver incorporates a bi-color (Red/Green) indicating LED for monitoring
proper system operation. See Figure 6 on Page 4 for LED Indicator explanations.
The FDX50M2 has a small footprint and is designed for surface mounting. The
FDX51M2 may be directly plugged into the ComNet Rack (Part C1) or can operate as
a standalone module, or may be DIN-rail mounted by the addition of ComNet model
DINBKT1 adaptor plate. See Figure A on Page 5 for mounting instructions.
See Figures 1 – 6 for complete installation details.
