The web page Help system contains detailed information and configuration procedures for each mode
discussed in SocketServer Architecture on Page 45.

5.1.2. SocketServer Architecture

TCP/IP socket mode operation
is used to connect serial
devices with an application
that supports TCP/IP socket
communications addressing.
Serial tunneling mode is used
to establish a socket
connection between two
ICDM-RX/TCPs through an
Ethernet network.
UDP mode is designed for applications that need faster data transmission, or that make use of UDP's
broadcast capabilities. UDP differs from TCP in that a UDP transmission does not first require a connection to
be opened before sending data and the receiving device does not issue acknowledgments to the sender.
