Convert your serial (RS232, RS422 or RS485) device(s) to 10/100 Ethernet with the DR2. This adapter does the job with no changes to your software.

The DR2 is an industrial device server packaged in a DIN-rail mountable plastic housing. The DR2 takes your serial data stream and converts it to Ethernet packets with no changes to your software. A Web Server is also built-in, which allows you to design your own pages and interface with your product from the Internet.

Flexible configuration options allow the DR2 to be set up locally using the serial port, or remotely over Ethernet using Telnet or a common web browser.

The DR2 works out of the box and comes with COM Port Redirector which allows you to redirect a PC serial port to Ethernet.
