4.2.4 Port Number
The
Port No
setting represents the source port number in TCP connections. It is the number that identifies
the channel for remote initiating connections. The port number functions as the TCP/UDP source port
number for outgoing packets. Packets sent to the unit with this port number are received to this channel. The
port number selected is the Incoming TCP/UDP port and Outgoing TCP/UDP source port.
Port No (10001) ? _
The current value is displayed in parentheses. The default setting for Port 1 is 10001. The range is 1-65535,
except for the following reserved port numbers:

(77FEh)
Note: Do NOT use the reserved port numbers for this setting as incorrect operation may result.
Use Port 1 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.
