Convert your serial Modbus RTU or ASCII (RS232, RS422 or RS485) device(s) to Modbus TCP 10/100 Ethernet with the Xpress DR IAP (DR2-MB). The DR2-MB is a Modbus industrial device server packaged in a din-rail mountable plastic housing that you use screw terminals and RJ45 to connect the 24VDC power and your serial ports. The DR2-MB takes your Modbus serial data stream and converts it to Modbus TCP Ethernet packets with no changes to your software.

A webserver is also built in which allows you to design your own pages and interface with your product from the Internet. The DR2-MB can also send e-mail messages when it detects a problem.

SOFTWARE: The DR2 allows the user to map serial Modbus to network Modbus.
