Serial Port Profiles
zUDP Entry 3
All hosts that have an IP Address that falls within the range of 172.16.1.75 to 172.16.1.80
and who listen to Port 33009 will receive UDP data from the serial device. The IOLAN will
listen for messages on the port value configured in the Listen for connections on UDP port
parameter. No UDP data will be sent to the serial device.
zUDP Entry 4
This entry is disabled since Direction is set to Disabled.
General Tab Field Descriptions
Configure the following parame ters:
Listen for
connections on
UDP port
The IOLAN will listen for UDP packets on the specified port.
Default: 1000+<port-number> (for example, 10001 for serial port 1)
Direction The direction in which information is received or relayed:
zDisabled—UDP service not enabled.
zLAN to Serial—UDP Port can be set to Auto Learn or Port. The IOLAN
will listen on port value configured in the Listen for connections on UDP
port parameter for messages coming from t he learn e d or config ured port.
zSerial to LAN—UDP Port can be set to Port only. The IOLAN will listen
on the port value configured in the Listen for connections on UDP port
parameter and will send to the confi gured port.
zBoth—Messages are relayed in both directions. UDP Port can be set to
Auto Learn or Port. For messages coming from the LAN to th e serial
device, IOLAN will listen on port value configured in the Listen for
connections on UDP port parameter for messages coming from the
learned or configured port. For messages going from the serial devi ce to
the LAN, the IOLAN will list en on the port value configured in the Listen
for connections on UDP port parameter and will send to th e configured
or learned (if Auto Learn is enabled, the IOLAN must receive a UDP
message before it can send one, since the port must first be ’learned’) port .
Default: Both for UDP 1 and Disabled for all other UDP ranges
Start IP Address The first host IP address in the range of IP addresses (for IPv4 or IPv6) that the
IOLAN will listen for messages from and/or send messages to.
Field Format: IPv4 or IPv6 address
End IP Addr ess The last host IP address in the range of IP addresses (for IPv4, not supported
for IPv6) that the IOLAN will listen for messages from and/or send messages
to.
Field Format: IPv4 address
