Code 39 Buffering (Scan & Store)
This feature allows the decoder 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 decoder to
decode Code 39 symbology only.
Buffer Code 39 (Enable)
Do Not Buffer Code 39 (Disable)
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 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 decoder issues a lo/hi beep to indicate
successful decode and buffering. (For overflow conditions, see Overfilling Transmission Buffer.)
• The decoder adds the decoded data excluding the leading space to the transmission buffer.
• No transmission occurs.
