Code 39 Buffering (Scan & Store)
Parameter # 71h
This feature allows the digital imager 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 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 Do Not Buffer Code 39 to transmit all decoded Code 39 symbols immediately without being stored in the 
buffer.
This feature affects Code 39 only. If selecting Buffer Code 39, Motorola recommends configuring the digital imager 
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 
) 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 digital imager scanner issues a low/high beep to 
indicate successful decode and buffering. For overflow conditions, see 
.
The digital imager scanner adds the decoded data excluding the leading space to the transmission buffer.
No transmission occurs.
