Digi RS-232 Devices

Digi offers a broad range of RS-232-based devices, including cellular routers and extenders for enterprise, industrial and transportation use cases, as well as serial servers and console servers for infrastructure management.

RS-232 (also called EIA-223) is one of the most common type of serial connectors in use today. It is compatible with a wide variety of systems and devices and supports out-of-band management for IT equipment and remote field devices. You can find additional information about Digi RS-232 devices, cabling and serial connections in the Digi Cable Guide, the Digi RS-232, RS-422 and RS-485 Technical Brief, and the documentation for your specific Digi product.
