UDP Server/Client

The UDP Server/Client operation mode is designed for applications that need

speedier data transmission, or that make use of UDP’s broadcast and multi-cast

capabilities. Keep in mind that UDP differs from TCP in that a UDP

transmission does not first require a connection to be opened before sending data,

and the receiving party does not issue acknowledgements to the sender.

Figure 3.5 illustrates a UDP

Server/Client Mode topology that

consists of one NPort connected

y a serial cable to a Card Reader.

The NPort automatically

transmits the card’s data over the

Ethernet to multiple computers.

We should point out that the

Delimiter 1, Delimiter 2, and

Force transmit options are used

to activate the optional Data

Packing function.
