Configuring UDP Multicast
The Digi One and PortServer TS devices are devices capable of UDP multicast. UDP multicast is used to send
serial data over an Ethernet cable to one or many hosts at the same time. UDP is a connectionless protocol,
meaning UDP does not need a protocol, but is sending data without any form of acknowledgement or error
correction. Up to 64 devices can receive a UDP multicast at one time. Both the transmitting and receiving
devices must be configured properly for UDP multicast to work.
This section describes how to use the web interface to configure this Digi device for the following:
• Inbound connections, that is, connections that are initiated by the device on the other side of the network
• Outbound connection, that is, connections that are initiated by the device connected to the serial port
Procedure for Configuring Outbound Socket Communication
1. Access the web interface by entering the Digi One/PortServer TS 2/4 IP address in a browser’s URL window.
2. Log in to the Digi One/PortServer TS as root. The default password is dbps.
3. From the main menu, choose Configure > Port.
4. From the Port configuration screen, set the Device type to Printer, adjust other serial port communication
parameters as required by the connected device, and then choose Advanced.
Note: The serial parameters for two connecting devices must match meaning if one device is set for 9600 bps, the other device
must be set for the same rate.
5.
Choose UDP serial... at the bottom of the page. The UDP Serial Configuration page is displayed.
