Port Number
The setting represents the source port number in TCP connections. It is the number that
identifies the channel for remote initiating connections. The default setting for Port 1 is 10001.
The range is 1-65535, except for the following reserved port numbers:
Reserved Port Numbers
Warning: 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, a random value of at least 50000 is used to actively establish a connection.
Each subsequent connection increments the number by 1. When the port number reaches
59999, it wraps around to 50000.
Only use the 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 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.
