4CH-RS232/485/422-ETH can transfer 4 serial ports to TCP/IP and support 2 10M/100M Ethernet ports. It supports the Modbus gateway function from Modbus TCP to Modbus RTU. The Modbus gateway supports simultaneous data reading over multiple Modbus clients, that is, the multi-host function. It supports 4 RS232 serial ports and 4 RS422/485 serial ports. Users connect the 4CH-RS232/485/422-ETH to the network through one network cable. The host computer can access 4 serial ports through the virtual serial port or TCP protocol. It can be expanded to 8 serial ports, 12 serial ports, 16 serial ports, or a maximum of 32 serial ports.
