Port Number
The setting represents the source port number in TCP connections. It is the n umber that
identifies the channel for remote initiating connections.
Port No (10001) ? _
The default setting for Port 1 is 10001. The range is 1-65535, except for the f ollowing
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. T he port range is
50,000 to 59,999. Each subsequent connection increments the number b y 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.
