Configurable Protocol

Configurable protocol is based on Intermec’s Polling Mode D protocol except that you have the option to change some of the serial port protocol parameters or remove specific events from the protocol, such as poll or handshake.

You can configure the following serial port parameters:

Baud rate

Data bits

Parity

Stop bits

Flow control

EOM (End of Message)

Configuration commands via serial port

LRC

SOM (Start of Message)

Handshake (enabled or disabled)

Poll (Polling) (enabled or disabled)

Timeout Delay

Configurable protocol uses EOM to determine one of the following serial communications modes.

Character mode When EOM is disabled, the terminal communicates in Character mode processing each character. Character mode supports both XON/XOFF and CTS/RTS flow control.

Frame mode When EOM is enabled, the terminal communicates in Frame mode. When a terminal sends a packet, it adds a protocol character. When a terminal receives a packet, it strips any protocol characters before it sends the information to the terminal application. Frame mode supports both XON/XOFF and CTS/RTS flow control. In Frame mode, you can also configure the following serial port parameters:

Configuration commands via serial port

Handshake

LRC

SOM

After you enable Handshake, you can define poll and timeout delay.
