Symbologies 10 - 41
Code 39 Buffering
Parameter # 113
This feature allows the digital scanner to accumulate data from multiple Code 39 symbols.
Enabling Code 39 Buffering temporarily buffers all Code 39 symbols having a leading space as a first
character for later transmission. The leading space is not buffered.
Decoding a 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 Disable Code 39 Buffering to transmit all decoded Code 39 symbols immediately without storing
them in the buffer.
This feature affects Code 39 only. If enabling Code 39 Buffering, we recommend configuring the digital
scanner to decode the Code 39 symbology only.
While there is data in the transmission buffer, you cannot select Disable Code 39 Buffering. 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 10-42) or clear the buffer.
Buffer Data
To buffer data, enable Code 39 Buffering and scan a Code 39 symbol with a space immediately following the
start pattern.
•
Unless the data overflows the transmission buffer, the digital scanner issues a low/high beep to indicate
successful decode and buffering. For overflow conditions, see Overfilling Transmission Buffer on page
10-42.
•
The digital 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, which contains only a start character, a dash
(minus), and a stop character.
•
The digital scanner issues a short high/low/high beep.
•
The digital scanner erases the transmission buffer.
•
No transmission occurs.
