Description

Widget World 440-0087-001 RS-232 to RS-422 Bidirectional Converter Card Rev H

This is a PCB-level converter card that translates signals between RS-232 and RS-422 serial communication standards in both directions. It was manufactured in 1989 and operates as a standalone module.

Specifications & What's Included

  • Model: 440-0087-001 (Rev H)
  • Type: RS-232 to RS-422 Bidirectional Converter Card
  • Form Factor: PCB Card/Module
  • Manufactured: United States, 1989
  • Card only; no additional accessories included

Applications

RS-232 to RS-422 converters are used to bridge communication between devices operating on different serial standards. RS-232 is single-ended and operates over shorter distances, while RS-422 uses differential signaling for longer-distance and more robust transmission. This bidirectional card allows legacy RS-232 equipment to communicate with RS-422 systems and networks commonly found in industrial control, telecommunications, and data acquisition environments.
