Buffer Data
To buffer data, Code 39 buffering must be enabled and a Code 39 symbol must
be read with a space immediately following the start pattern.
y
Unless the data overflows the transmission buffer, the decoder
issues a lo/hi beep to indicate successful decode and buffering.
(For overflow conditions, see
Overfilling Transmission Buffer .)
y
The decoder adds the decoded data excluding the leading space to
the transmission buffer.
y
No transmission occurs.
Clear Transmission Buffer
To clear the transmission buffer, scan the Clear Buffer bar code below, which
contains only a start character, a dash (minus), and a stop character.
y
The decoder issues a short hi/lo/hi beep.
y
The decoder erases the transmission buffer.
y
No transmission occurs.
Clear Buffer
Note: The Clear Buffer contains only the dash (minus) character. In order to
scan this command, be sure Code 39 length is set to include length 1.
Transmit Buffer
There are two methods to transmit the Code 39 buffer.
1. Scan the Transmit Buffer bar code below. Only a start character, a
plus (+), and a stop character.
y
The decoder transmits and clears the buffer.
y
The decoder issues a Lo/Hi beep.
Transmit Buffer
2. Scan a Code 39 bar code with a leading character other than a
space.
y
The decoder appends new decode data to buffered data.
y
The decoder transmits and clears the buffer.
y
The decoder signals that the buffer was transmitted with a lo/hi
beep.
y
The decoder transmits and clears the buffer.
