Symbologies
While there is data in the transmission buffer, selecting Do Not Buffer Code 39 is not
allowed. The buffer holds 200 bytes of information.
To disable Code 39 buffering when there is data in the transmission buffer, first force
the buffer transmission (see
Transmit Buffer on page 11-40) or clear the buffer.
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.
• Unless the data overflows the transmission buffer, the scanner issues a lo/hi beep
to indicate successful decode and buffering. (For overflow conditions, see
Overfilling Transmission Buffer .)
• The scanner adds the decoded data excluding the leading space to the
transmission buffer.
• 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.
• The scanner issues a short hi/lo/hi beep.
• The scanner erases the transmission buffer.
• 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.
