Transmit Buffer
There are two methods to transmit the Code 39 buffer.
1. Scan the Transmit Buffer bar code below, which includes only a start character, a plus (+), and a stop
character.
2. The digital scanner transmits and clears the buffer.
• The digital scanner issues a low/high beep.
3. Scan a Code 39 bar code with a leading character other than a space.
• The digital scanner appends new decode data to buffered data.
• The digital scanner transmits and clears the buffer.
• The digital scanner signals that it transmitted the buffer with a low/high beep.
• Digital scanner transmits and clears the buffer.
Overfilling Transmission Buffer
The Code 39 buffer holds 200 characters. If the symbol just read overflows the transmission buffer:
• The digital scanner indicates that it rejected the symbol by issuing three long, high beeps.
• No transmission occurs. The data in the buffer is not affected.
Attempt to Transmit an Empty Buffer
If you scan the Transmit Buffer symbol and the Code 39 buffer is empty:
• A short low/high/low beep signals that the buffer is empty.
• No transmission occurs.
• The buffer remains empty.
Transmit Buffer
NOTE The Transmit Buffer contains only a plus (+) character. In order to scan this command, set Code 39
lengths to include length 1.
