Serial Port Profiles

UDP Sockets Profile

Overview

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

Functionality

When you configure UDP, 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 “LAN to Serial”, the following options are available:

zTo receive data from a specific IP address, enter this address in the Start IP Address field and leave the End IP Address field at its default value (0.0.0.0). For the port, you can enter a specific “source” port or leave as 0 to accept any source port.

zTo receive data from a range of IP address, fill in the Start IP Address field with the low IP address for the range and the End IP Address field with the high IP address for the range.

zTo receive data from any IP address and any UDP port, leave the Start IP Address field, the End IP Address field and the Port 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.

zIf the Start IP Address field is set to 255.255.255.255 and the End IP Address is left at its default value (0.0.0.0), 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 Start IP Address field at its default value (0.0.0.0).

When you configure UDP for “Serial to LAN”, the following options are available:

zTo send data to a specific IP address, enter this address in the Start IP Address field and leave the End IP Address field at its default value (0.0.0.0).

zTo send data to a range of IP address, fill in the Start IP Address field with the low IP address for the range and the End IP Address 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.
