Code 39 Buffering (Scan & Store) - Symbol LS2208 Product Reference Manual

12 - 28 Symbol LS2208 Product Reference Guide
Code 39 Buffering (Scan & Store)
This feature allows the scanner to accumulate data from multiple Code 39 symbols.
When you select the Scan and Store option (Buffer Code 39), 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, all decoded Code 39 symbols are transmitted immediately
without being stored in the buffer.
This feature affects Code 39 only. If you select Buffer Code 39, we recommend that you configure 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 Transmit Buffer on page
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

The scanner adds the decoded data excluding the leading space to the transmission buffer.

No transmission occurs.
