ANSI X3.28 to Modbus RTU - Serial to Modbus RTU Converter

Deigned for legacy systems where there is a need to replace older X3.28 protocol Controllers and with new Modbus RTU Controllers. The Model 2399 provides ANSI X3.28 to Modbus RTU Conversion without changing the existing system software. The 2399 also provides serial control of Modbus RTU devices for new applications that want the ease of using simple ASCII commands when controlling Modbus RTU devices.
