User Manual V. 1.1
3.4.1 TCP Server
SE5002D is configured by default as TCP Server mode, there are additional connection
settings that can be configured. By selecting the TCP Server mode, a TCP Client program
should be prepared to connect to SE5002D.
 Click on “COM1” link on the left hand side.
 Select TCP Server. TCP Server is the default link mode.
 Enter the Local Listening Port. This is the port specified in the TCP Client program
connecting to the serial device server. The default local port is 4660.
 IP Filter; only the designated IP address will be able to access the COM port if this option
is enabled. This option is disabled by default.
 TCP Keep-Alive; specify the interval in the “Idle Time Before Sending TCP Alive
Packet ” to force SE5002D to send TCP Keep-Alive packets in the set interval to prevent
disconnection from the client. Note that this field has a 10 multiplier, so the default value
4 means to send Keep-Alive packets every 40 seconds.
 TCP Inactivity Timeout; specify the value in “TCP Inactivity Time Before Disconnect”
to force SE5002D actively close a TCP connection after some specific inactivity time (no
packets). The default value is 0, which means SE5002D would never actively close an
established connection.
