4.2.3. Host Mode Configuration

The Pro Series operating mode is called the “host mode.” Three host modes are available: TCP mode,

UDP mode, Modem emulation mode.

TCP mode

The Pro Series works as both TCP server and client. This mode works for most applications, since it

will transfer the data either from serial port or from TCP port. If there is no connection established on a

TCP port, the TCP port accepts a connection request from any registered remote hosts and relays the

transmitted data to the coupled serial port. If there is any data from the serial port, it connects to the

registered remote hosts and redirects the data.

UDP mode

The UDP mode operation is similar to that of TCP mode except that it utilizes UDP protocol.

Modem emulation mode

Select this mode when the serial device already supports modem AT commands or users want to

perform the session control by using AT commands. Only TCP session is supported.

Figure 4-4 shows the main workspace screen for the host mode configuration.
