Symbologies 10 - 33 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. Buffer Code 39 (Enable) (01h) *Do Not Buffer Code 39 (Disable) (00h) 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 10-34) 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 Overfilling Transmission Buffer. • The digital imager scanner adds the decoded data excluding the leading space to the transmission buffer. • No transmission occurs.
