TCP Client Mode

SE5408/SE5416 Multi-Port Serial Server can be configured as a TCP client which initiates a TCP

connection request to a host computer or server as shown in Fig 8. The maximum number of host

computers for TCP connection request is two computers. To configure each serial port of the device

server as a TCP Client, one of the four configuration methods (Web-based program, Telnet, Serial

Console, and SerialManager) can be used. The configuration of the device server is explained in more

details in the next chapters.

Fig 9 shows three TCP clients (connected with three different card readers) share a same host computer,

which acts as the TCP server, with the IP address of 10.0.0.100 and the listening port number of 1000.

The SE5408/SE5416 Multi-Port Serial Server series in TCP Client mode allows connecting up to two

destination host computers.
