Socket Port Configuration

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

DeviceMaster 500s 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.
