Data Communications and Operating Options

If a host message interrupts a data transmission, the reader:
1. Sends a carriage return line feed (CR LF) to the terminal
2. Displays the host message on the terminal
3. Sends a CR LF to the terminal
4. Displays the entire contents of the preamble and data buffers on the
terminal
Use one of these protocols when the terminal is in full-duplex:
• Point-to-Point
• Polling Mode D
• Multi-Drop
• User-Defined
Although you can configure the terminal in half-duplex, Intermec does not
recommend it.
Transparent Terminal Operation
When the terminal is set to transparent operation, the host formats the terminal
screen and the terminal does not display diagnostic messages. The reader
accepts limited commands from the terminal.
The reader buffers data from both the terminal and scanner and displays the
unformatted data on the terminal screen. The reader transmits the data to the
host when one of these events occurs:
• The reader receives a Transmit command.
• The reader scans a regular label.
• You press Enter from the terminal keyboard.
Use one of these protocols when the terminal is in full-duplex:
• Point-to-Point
• Polling Mode D
• Multi-Drop
• User-Defined
Although you can configure the terminal in half-duplex, Intermec does not
recommend it.
