TCP Sockets
TCP socket communication enables serial devices to communicate with each other over an Ethernet network as though they were connected by a serial cable.
Configuring TCP socket communications involves configuring the Digi device for the following types of connections:
•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.
Note: TCP Sockets profile is also the profile to use for Autoconnection. See "Click Reboot for changes to take effect." on page 33 for more information.
UDP Sockets
The Digi TS Family devices are 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.
Configuring UDP multicast communications involves configuring the Digi device for the following types of connections:
•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.
