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

DeviceMasters 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 acknowledgements to the sender.
