Serial Port Profiles

142 

IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.0

The UDP profile configures a serial port to broadcast UDP data to systems and/or receive UDP data 
from systems.

When you configure 

, you are setting up a range of IP addresses and the port numbers that you 

will use to send serial data to the LAN (using UDP) or receive UDP data from the LAN which will be 
forwarded to the serial port.

When you configure UDP for 

, the following options are available: 

z

To receive data from a specific IP address, enter this address in the 

 field and 

leave the 

 field at its default value (

). For the port, you can enter a 

specific “source” port or leave as 0 to accept any source port. 

z

To receive data from a range of IP address, fill in the 

 field with the low IP 

address for the range and the 

 field with the high IP address for the range.

z

To receive data from any IP address and any UDP port, leave the 

 field, the 

 field and the 

field at its default value of 0. The IP address on the first UDP 

message received will than be the only IP address accepted from that point on. This is the “auto 
learn” feature of the UDP profile.

z

If the 

 field is set to 

 and the 

 is left at its 

default value (

), the IOLAN will accept UDP packets from any source address. If you 

want the IOLAN to receive data only from the first IP address is sees (auto learn the sender IP 
address), leave the 

 field at its default value (

).

When you configure UDP for 

, the following options are available: 

z

To send data to a specific IP address, enter this address in the 

 field and leave 

the 

 field at its default value (

). 

z

To send data to a range of IP address, fill in the 

 field with the low IP address 

for the range and the 

 field with the high IP address for the range. A separate 

UDP message with the same serial data will be sent to each host in the configured range.
