Transmit Buffer

There are two methods to transmit the Code 39 buffer.

1.

Scan the Transmit Buffer bar code below which contains only a start character, a plus (+), and a stop
character.

The scanner transmits and clears the buffer.

The scanner issues a low/high beep.

2.

Scan a Code 39 bar code with a leading character other than a space.

The scanner appends new decode data to buffered data.

The scanner transmits and clears the buffer.

The scanner signals that the buffer was transmitted with a low/high beep.

Scanner transmits and clears the buffer.

Overfilling Transmission Buffer

The Code 39 buffer holds 200 characters. If the symbol just read results in an overflow of the transmission buffer:

The scanner indicates that the symbol was rejected by issuing three long, high beeps.

No transmission occurs. The data in the 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:

A short low/high/low beep signals that the buffer is empty.

No transmission occurs.

The buffer remains empty.

NOTE

Because the Clear Buffer contains only the dash (minus) character, set the Code 39 length to include
length 1 before scanning this bar code.

Transmit Buffer

NOTE

Because the Transmit Buffer contains only a plus (+) character, set the Code 39 length to include length 1
before scanning this bar code.
