Code 39 Buffering (Scan & Store)
Parameter # 71h
This feature allows the digital scanner to accumulate data from multiple Code 39 symbols.
Select the Scan and Store option ( Buffer Code 39 ) to temporarily buffer all Code 39 symbols with a leading space
as a first character for later transmission. This does not buffer the leading space.
Decoding a valid Code 39 symbol with no leading space transmits in sequence all buffered data in a first-in first-out
format, plus the “triggering” symbol. See the following pages for further details.
Select the Do Not Buffer Code 39 option to transmit all decoded Code 39 symbols immediately without storing
them in the buffer.
This feature affects Code 39 only. If selecting Buffer Code 39 , for best performance, configure the digital scanner
to decode Code 39 symbology only.
While there is data in the transmission buffer, you cannot select Do Not Buffer Code 39 . 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 10-35 ) or clear the buffer.
