Comnet FDX57M1 RS232/422/485 2&4W Digitally Encoded Self-Healing Ring

RS232/422/485 2&4W Digitally Encoded Self-Healing Ring, mm, 1 fiber. The ComNet FDX57M1 Ring Transceiver unit is a fully-digital modem designed for implementing RS232, RS422 or RS485 2 4-wire data communications networks of highest possible reliability. network FDX57 units can support one full-duplex two half-duplex channels. These transceivers also feature translation to convert between protocols. re-clocking and regeneration permit an almost unlimited number transceiver/controller be used within network. environmentally hardened are ideal use in unconditioned out-of-plant roadside installations and, unlike many competing designs, only optical fiber required implement fully ring. Plug-and-play design ensures ease installation, no electrical adjustments ever required.
