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 decoder transmits and clears the buffer.
•
The decoder issues a low/high beep.
3.
Scan a Code 39 bar code with a leading character other than a space.
•
The decoder appends new decode data to buffered data.
•
The decoder transmits and clears the buffer.
•
The decoder signals that it transmitted the buffer with a low/high beep.
•
The decoder 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 decoder 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.
Clear Buffer
NOTE
The Clear Buffer contains only the dash (minus) character. In order to scan this command, set Code 39
lengths to include length 1.
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.
