16CH-RS232/485/422-ETH is a standard 1U rack-mount converter for 16 RS232/485/422 and TCP/IP protocols. It supports 16 RS232 serial ports/16 RS485/RS422 serial ports and RS232 supports flow control. Connecting to the 16CH-RS232/485/422-ETH via a single network cable enables all 16 serial ports to operate simultaneously in full-duplex mode. Each serial port can function as a TCP server, TCP client, UDP, or UDP multicast. It also supports 4 network ports with switch functionality.
