Port Number
The setting represents the source port number in TCP connections. It is the number that
identifies the channel for remote initiating connections.
Port No (10001) ? _
The default setting for port 1 is 10001. The default setting for Port 2 is 10002. The range
is 1-65535, except for the following reserved port numbers:
Table 9-4. Reserved Port Numbers
Warning: We recommend that you not use the reserved port numbers for
this setting as incorrect operation may result.
Use Port 0 for the outgoing local port to change with each connection. The port range is
50,000 to 59,999. Each subsequent connection increments the number by 1 (it wraps
back around to 50,000).
Only use this automatic port increment feature to initiate a connection using TCP. Set the
port to a non-zero value when the unit is in a passive mode or when using UDP instead
of TCP.
