Binary Protocol
Binary protocol has no protocol. Characters are sent and received without being altered.
The Data Link Escape character (DLE) is not inserted before any character. DLE
characters are not stripped out of the incoming data stream and no characters such as
EOM or SOM are added.
Here are the serial port parameters you can define:
• Baud rate
• Data bits
• Parity
• Stop bits
• Flow control
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. Here are the serial port parameters
you can define:
• Baud rate
• Data bits
• Parity
• Stop bits
• Configuration commands via serial port
• EOM (End of Message)
• Flow control
• Handshake (enabled or disabled)
• LRC
• Poll (Polling) (enabled or disabled)
• SOM (Start of Message)
• Timeout Delay
Configurable protocol uses EOM to determine the serial communications mode. When
EOM is disabled, the terminal communicates in Character mode. When EOM is enabled,
the terminal communicates in Frame mode. Once EOM is enabled, you can set a value
for these serial port parameters:
• Configuration commands via serial port
• Handshake
• LRC
• SOM
Once Handshake is enabled, you can set a value for poll and the timeout delay.
