Programming the Scanner
Code 39 Buffering (Scan & Store)
When you select the Buffer Code 39 option, all Code 39 symbols having a leading space as a
first character are temporarily buffered in the unit to be transmitted later. The leading space
is not buffered.
Decode of a valid Code 39 symbol with no leading space causes transmission in sequence of
all buffered data in a first-in first-out format, plus transmission of the “triggering” symbol.
See the following pages for further details.
When the Do Not Buffer Code 39 option is selected, decoded Code 39 symbols without
leading spaces are transmitted immediately.
Scan and Store affects Code 39 decodes only. If you select scan and store, we recommend that
you configure the scanner to decode Code 39 symbology only.
Buffer Code 39
(Enable)
Do Not Buffer Code 39
(Disable)
While there is data in the transmission buffer, disabling Code 39 buffering via the
parameter menu is not allowed. The buffer holds 200 bytes of information.
To allow disabling of Code 39 buffering, first force the buffer transmission (see
Transmit
Buffer
) or clear the buffer. Both the
CLEAR BUFFER
and
TRANSMIT BUFFER
bar codes
are length 1.
Be sure Code 39 length is set to include length 1.
