The DR2-MB is a Modbus industrial device server packaged in a din-rail mountable plastic housing that uses screw terminals and RJ45 to connect the 24VDC power and your serial ports.
Modbus, Modbus TCP/IP
The DR2-MB takes a Modbus serial data stream and converts it to Modbus TCP Ethernet packets with no changes to your software. A web server is also built in to the DR2-MB, 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. The DR2 allows the user to map serial Modbus to network Modbus.
