Port Number
Every TCP connection and every UDP datagram has a destination IP address and a
port number. A port number is similar to an extension on a PBX system. For
example, a Telnet application commonly uses port number 23. Port number 9999 is
reserved for access to the unit's Setup Mode.
The Port Number setting represents the source port number in TCP connections. It is
the number that identifies the channel for remote initiating connections. For example,
to send data to channel 1, send TCP/UDP packets to this assigned port number.
The default setting for port 1 is 10001. The range is 1-65535, except for the following
reserved port numbers:
