Overview

The Patton Electronics 222NSM is an interface-powered RS-232 to RS-422/485 converter. This compact unit, no larger than a DB-25 or DB-9 backshell, features built-in surge protection to safeguard sensitive equipment from transient voltage spikes. It operates asynchronously, supporting transmit and receive data signals, with EIA-232 control signals wired together for simplified operation. The 222NSM supports data rates up to 19,200 bps and draws power directly from the RS-232 interface, eliminating the need for external power sources. Ideal for extending RS-232 communication up to 4,000 ft (1,219 m) over two twisted-pair wires, it is suitable for space-constrained applications.
