Introduction
MDC-700 provides Ethernet, RS-232 and RS-485 communication interfaces to integrate RS-232/RS-485 Modbus Slave devices into Ethernet. Through the user-defined command table, the MDC-700 will read the data of the devices connected to each COM port sequentially and merge them into a continuous address format, which is convenient for the host computer to read all the data at once.
