off. If port sharing is enabled for 2 and then disabled, the change will not
take effect until everyone is off. The default value when port sharing is
disabled is one.
TCP Sockets
The Digi One IA/SP and the Digi TS Family devices support TCP socket
communication. 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 "About
Autoconnection" on page 38 for more information.
UDP Sockets
The Digi One IA/SP and 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 does not need a protocol
because it sends data without any form of acknowledgment of error 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 connections, that is, connections that are initiated by the
device connected to the serial port.
