RS-232 to RS-485/RS-422 Converters

RS-232 to RS-422/RS-485 bidirectional converters

with point-to-point, multidrop and simplex/duplex selectability, supporting up to 32 receivers and extending up to 4000 feet

IC485S, IC485SN, and IC485AI are hardware solutions to the problem of converting signals between two standards. They are converters that convert RS-232 signals to RS-422/RS-485 signals (and vice versa), thus permitting the creation of reliable long distance communication systems using standard computer hardware.

Data transfer can take place at up to 1200 meters (4000 feet), over four or two wire cables for full or half duplex, respectively. The converters can handle any RS-485/RS-422 device allowing it to function as a short haul modem or interface converter. Request to send (RTS) selection allows up to 32 receivers to be set up in a multidrop installation, making for a cost effective network configuration.
