Transmit Buffer
There are two methods to transmit the Code 39 buffer.
Scan the Transmit Buffer bar code which contains only a start character, a plus (+), and a stop character.
1.
•
The scanner transmits and clears the buffer.
•
The scanner issues a low/high beep.
Scan a Code 39 bar code with a leading character other than a space.
2.
•
The scanner issues a high/low beep to indicate a good decode and that decode data was buffered.
•
The scanner transmits and clears the buffer.
•
The scanner signals transmission of the buffer with a low/high beep.
NOTE The Transmit Buffer contains only a plus (+) character. In order to scan this command, be sure to set a
Code 39 length to include length 1.
Overfilling Transmission Buffer
The Code 39 buffer holds 200 characters. If a symbol decode results in an overflow of the transmission buffer:
•
The scanner issues three long, high beeps to indicate that it rejected the symbol.
•
No transmission occurs. This does not affect the data in the buffer.
Attempt to Transmit an Empty Buffer
If the symbol just read was 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.
