RS-422 Communication Interface

The RS-422 serial communication interface handles data structures of the same format as those for the serial communication interface. However, the RS-422 interface can transfer data over distances of up to 4000 feet (1219 meters) with minimal noise interference.

Current Loop Communication Interface

The current loop (TTY) interface uses a four-wire, passive, neutral current loop which does not interfere with the standard serial interface. The printer can receive data via either interface, provided the other interface is in a spacing condition or its cable is disconnected.

WARNING: Interface cables installed as part of the building wiring must conform to the requirements of the U.S. National Electrical Code. Contact your local inspector to determine that the correct materials have been chosen for your installation.
