Anaheim Automation DC2170 Bidirectional RS-232 to RS-422 Converter

The Anaheim Automation DC2170 Bidirectional RS-232 to RS-422 Converter is a purpose-built interface that bridges RS-232 serial equipment with RS-422 networks, enabling true bidirectional data flow between devices that speak these different serial standards. Powered by a dedicated 9 VDC supply, the unit uses a 9-pin RS-232 connector on the serial side (the standard DB9 interface common to many legacy devices), while the RS-422 side provides differential signaling suitable for longer runs and noisier environments. Designed for industrial automation, data acquisition, and lab setups, this converter minimizes the need to replace older equipment by translating signals in both directions, helping systems integrate PC consoles, controllers, or instruments with RS-422 capable networks. Key considerations when selecting DC2170 include confirming external power availability (9 VDC), ensuring a DB9 RS-232 interface matches your device, and aligning with RS-422 requirements for your network topology to achieve reliable, two-way communication.
