Note: We recommend that you not use the reserved port numbers for
this setting as incorrect operation may result.
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. Use Port 0 when you want the outgoing source port to change with each
connection.
If the port number is 0, the initial value of 5000 actively establishes a connection.
Each subsequent connection increments the number by 1. When the port number
reaches 7999, it wraps around to 5000.
Only use the automatic port increment feature to initiate a connection using TCP. Set
the port a non-zero value when the unit is in a passive mode or when you are using
UDP instead of TCP.
Connect Mode
Connect Mode defines how the unit makes a connection, and how it reacts to
incoming connections over the network. Enter Connect Mode options in hexadecimal
notation.
