Symbologies 12 - 29 Code 39 Buffering (Scan & Store) This feature allows the 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. The leading space is not buffered. 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 details. Select Do Not Buffer Code 39 to transmit all decoded Code 39 symbols immediately without storing them in the buffer. This feature affects Code 39 only. If you select Buffer Code 39, Motorola recommends configuring the scanner to decode Code 39 symbology only. Buffer Code 39 (Enable) *Do Not Buffer Code 39 (Disable) 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 12-30) 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 scanner issues a low/high beep to indicate successful decode and buffering. (For overflow conditions, see Overfilling Transmission Buffer.) • The scanner adds the decoded data excluding the leading space to the transmission buffer. • No transmission occurs.
