Transmit Buffer
To transmit the buffer, read a symbol containing either the first or second
condition:
1. Only a start character, a plus (+), and a stop character, such as the bar code
below.
•
The unit signals that the transmission buffer has been sent (a lo/hi beep).
•
Unit sends the buffer.
•
Unit clears the buffer.
2. A Code 39 bar code with leading character other than a space.
•
The unit signals that a good decode and buffering of that decode has
occurred by giving a lo/hi beep.
•
Unit transmits the buffer.
•
Unit signals that the buffer has been transmitted.
Overfilling Transmission Buffer
If the symbol just read will result in an overflow of the transmission buffer:
•
Unit indicates that the symbol has been rejected by issuing three long,
high beeps.
•
No transmission will occur.
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 lo/hi/lo beep signals that the buffer is empty.
•
No transmission occurs.
•
The buffer remains empty.
