Two-port serial-to-Ethernet adapter

The StarTech.com I23-SERIAL-ETHERNET connects two DB9 RS232 devices to a local area network for remote management. It suits industrial technicians and IT administrators who need to access legacy serial equipment from a central console. The unit includes a DIN rail mounting kit and a universal power adapter for quick installation in cabinets or on walls.

Sustained network operation

The device server maintains continuous TCP/IP communication with attached serial ports during extended monitoring sessions. It handles persistent connections without requiring host-PC software to stay active once configured. The hardware is designed for always-on duty in automation, building-control or remote-access scenarios.

Passive cooling and low draw

The enclosure dissipates heat without fans, so acoustic output is negligible in equipment rooms. Power consumption remains modest under the supplied universal adapter, keeping thermal load low inside closed cabinets. The compact form factor fits standard DIN rail spacing without blocking adjacent modules.

Questions about this item

Does the I23-SERIAL-ETHERNET adapter generate much heat or noise when running continuously?

The device has no moving parts and draws power from the included universal adapter, so it runs silently with minimal heat during all-day operation.

What cabling or infrastructure must I already have to use the two DB9 ports over the network?

You need an Ethernet LAN connection and RS-232 serial cables with DB9 connectors for each device you want to link to the server.

Will this server work with legacy RS-232 equipment that only supports lower baud rates?

Yes, the serial ports handle standard RS-232 signalling, so older devices that communicate at lower speeds will connect without changes.
