TRANSMIT BUFFER
2.
A Code 39 bar code with leading character other than a space.
•
The scanner signals a good decode and buffering of that decode has occurred by
emitting a hi/lo beep.
•
The scanner transmits the buffer.
•
The scanner signals that the transmission buffer has been sent (a hi/lo beep).
Overfilling Transmission Buffer
If the symbol just read results in an overflow of the transmission buffer:
•
The scanner indicates that the symbol has been rejected by issuing three long,
high beeps.
•
No transmission occurs. Data in buffer is not affected.
Attempt to Transmit an Empty Buffer
If the symbol just read was the transmit buffer symbol and the Code 39 buffer is empty:

No transmission occurs.
