Figure 4-5 State Transition Diagram of TCP mode

4.2.3.2. UDP mode

The UDP mode operation is similar to that of TCP mode except that it is based on UDP protocol and

only one pre-defined remote host is able to communicate with the Pro Series. Users do not have to

configure cyclic connection, since UDP is a connectionless protocol.
