TCP Server mode is the default Link mode of serial communication. In the TCP Server mode, the device
will listen for a client to establish a TCP connection. Once the connection is established, data can flow in
both directions. The default listening ports of the device TCP server (Local Port) is 4660 for COM1, 4661
for COM2, 4662 for COM3, and so on.
IP filtering function is a simple Access Control List (ACL) to allow only a set of computer hosts to access
the device’s TCP server. Set “IP Filter” to “0.0.0.0” to disable “
IP filtering function
”. If IP filter is enabled,
one may configure one or group IP addresses of computer hosts that are allowed to establish TCP
connections.
