Introduction
RS-422 Port-powered Converter

These port-powered converters change RS-232 TD and RD to balanced RS-422 signals extending communication distances up to 1.2 km. Port-powered from the RS-232 DTR and RTS handshake lines, no power supply is needed. 

At least one handshake line must be present, in either a positive or negative voltage state. No worry about software control of the handshake lines. If port power is not sufficient, model ULI-223T can be powered from an external PSU.

Converters are configured to transmit both directions in an RS-232and RS-422 system. 

RS-232 pinout connects directly to a computer’s COM port or any other DTE device.
