Product information

Description

The StarTech.com 2-Port Serial to Ethernet Adapter (I23-SERIAL-ETHERNET) enables remote access and control of RS232 serial devices over IP networks. Housed in a rugged metal enclosure with included wall and DIN-rail mounting hardware, the adapter supports IEEE 802.3 Ethernet and provides a compact, mountable solution for connecting serial equipment to an Ethernet infrastructure.

Advantages

This DB9 to Ethernet converter supports two RS232 ports and a single RJ45 10/100 Mbps Ethernet interface, offering flexible network connectivity via Telnet Server (RFC2217), TCP Server, TCP Client, and UDP protocols. The device includes both DC jack and terminal-block power inputs, a universal power adapter, Level-4 ESD protection (15 kV air / 8 kV contact), and the option to supply 5 VDC on pin 9. A full metal chassis and multiple mounting points simplify installation in industrial or office environments.

Suitable for

Remote management of RS232 instruments and controllers
Connecting serial devices to IP-based monitoring systems
Industrial automation and legacy equipment integration
Environments requiring wall or DIN-rail mounting

How to use

Connect your RS232 devices to the DB9 serial ports and link the adapter to the network via the RJ45 Ethernet port.

Usage recommendations

For reliable operation, mount the adapter using the supplied hardware to secure orientation and airflow. Use the WebUI for platform-independent management and the Windows Virtual COM Port utility when virtual COM port integration is required.
