Port Number
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 0 is used when you want
the outgoing source port to change with each connection.
Port No (10001) ? _
Default setting for Port 1 is 10001. Range: 0-65535 except for the following reserved port
numbers:

Recommended ports, should be used for DeviceComm Manager
(COM1-COM256) or direct socket connections
Warning:
We recommend that you not use the reserved port numbers for this setting as
incorrect operation may result.
Use Port

for the outgoing local port to change with each connection. The port range is
50,000
-
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.
Connect Mode
Connect Mode defines how the unit makes a connection, and how it reacts to incoming
connections over the network.
ConnectMode (C0) ? _
Enter Connect Mode options in hexadecimal notation. The default setting is
C0
.
Note:
See Table 11-1 Binary to Hexadecimal Conversion Table. All bit positions in the table that
are blank represent “don’t care” bits for that particular option, which can be set to either a 0 or 1
value.
