Motorola DS3478 Manuale Utente

Symbologies 13 - 31

This feature allows the digital scanner to accumulate data from multiple Code 39 symbols.

Select 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. Since this feature affects Code 39 only, for best performance 
configure the digital scanner to decode the Code 39 symbology only.

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 Do Not Buffer Code 39  to transmit all decoded Code 39 symbols immediately without storing in the buffer.

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.

To buffer data, enable Code 39 buffering and read 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 

.

The digital scanner adds the decoded data excluding the leading space to the transmission buffer.

No transmission occurs.
