12 - 28 Symbol LS3008 Product Reference Guide
Code 39 Buffering (Scan & Store)
This feature allows the scanner to accumulate data from multiple Code 39 symbols.
Selecting the Scan and Store option (Buffer Code 39) temporarily buffers all Code 39 symbols having a leading
space as a first character for later transmission. 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, all decoded Code 39 symbols are transmitted immediately
without being stored in the buffer.
This feature affects Code 39 only. If selecting
Buffer Code 39
, we recommend configuring the scanner to decode
Code 39 symbology only.
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
) 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 low/high 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 high/low/high beep.
•
The scanner erases the transmission buffer.
