4 BI-DIRECTIONAL DATA CHANNELS

The ComNet™ FDX4D(M)(S)1 Series data transceiver series provide transmission
of four bi-directional data channels over one optical fiber and are ideal for use in
unconditioned roadside or out-of-plant installations. The data channels can be set
independently for RS232, RS422 and 2 or 4-wire RS485 with tri-state support. See
Figures 3 – 5 starting on Page 3 for a description of data settings.

Each transceiver incorporates a bi-color (Red/Green) indicating LED for monitoring
proper system operation. See Figure 6 on Page 5 for LED Indicator explanations.

The FDX4D(M)(S)1 may be directly plugged into the ComNet Rack (Part C1) or can
operate as a standalone module. See Figure A on Page 6 for mounting instructions.
