Symbologies 13 - 35 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 digital scanner transmits and clears the buffer. • The digital scanner issues a low/high beep. Transmit Buffer 3. Scan a Code 39 bar code with a leading character other than a space. • The digital scanner appends new decode data to buffered data. • The digital scanner transmits and clears the buffer. • The digital scanner signals that it transmitted the buffer with a low/high beep. • Digital scanner transmits and clears the buffer. NOTE The Transmit Buffer contains only a plus (+) character. In order to scan this command, set Code 39 lengths to include length 1. Overfilling Transmission Buffer The Code 39 buffer holds 200 characters. If the symbol just read overflows the transmission buffer: • The digital scanner 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.
