UDP Sockets port profile

The Digi device is 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 does not need a protocol because it sends data without any form of acknowledgment of error or error correction.

The number of devices that can receive a UDP multicast varies by product.

• PortServer TS 8/16 Family: up to 16 devices can receive a UDP multicast at one time.
• All other products, including the Digi One Family and PortServer TS 1/2/4: 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.

Configuring UDP multicast communications involves configuring the Digi device for the following types of connections:

• Inbound connections (UDP server): Connections that are initiated by the device on the other side of the network.
• Outbound connections (UDP client): Connections that are initiated by the device connected to the serial port on the Digi device.

When you use UDP port profile, you are connecting a device with a serial port to the serial port on the Digi device. The serial parameters for both devices must match. For example, if the serial port for the device connected to the Digi device is set for 9600 bps, the serial port on the Digi device must also be set for 9600 bps.
