Understanding the Barcode Scanner
1.2 MEMORY
The collected data can be sent back to a host computer one by one via the WPAN
connection or stored in flash memory when the scanner is set to Memory mode.
1.2.1 TRANSMIT BUFFER
By default, transmit buffer is enabled and for use when the scanner is out of range. Upon
reading a barcode successfully within range, the scanner responds with one short beep
(high tone) and its LED indicator becomes solid green and goes off quickly. However, the
host computer may not receive the data immediately if getting out of range. With the 4
KB transmit buffer, the scanner can ignore the transmission status and keep on reading
barcodes until the buffer is full.
When transmit buffer is enabled…
If the scanner is out of range, it will respond with two short beeps, high-low tone, upon reading a
barcode successfully.
When transmit buffer is full, the scanner will respond with one long beep (low tone) and its LED
indicator will become solid red and go off quickly. You are advised to get back to range.
When transmit buffer is disabled…
If the scanner is out of range, it will respond with one long beep (low tone) and its LED indicator
will become solid red and go off quickly. You are advised to get back to range.

Note: The 4 KB transmit buffer on the scanner can hold as many as 256 scans based on
EAN-13 barcodes. Data will be cleared out once the scanner is turned off or
running out of battery power!
