1660 Barcode Scanner
User Guide
1.2 MEMORY
The collected data can be sent back to a host computer one by one via the transmit
buffer (SRAM) or stored in flash memory when the scanner is set to Memory mode.
1.2.1 TRANSMIT BUFFER
The scanner is designed to send any collected data to a host computer one by one via
the transmit buffer (SRAM). Upon reading a barcode successfully, 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 1 KB transmit buffer, the scanner can ignore the transmission status
and keep on reading barcodes until the buffer is full.
 A warning is given when the 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.
Note: The 1 KB transmit buffer on the scanner can hold as many as 64 scans based on
EAN-13 barcodes. Data will be cleared out once the scanner is turned off or
running out of battery power!
1.2.2 MEMORY MODE
The scanner keeps 256 KB flash memory for memory mode operation. When the 1660
scanner is in memory mode, it means a WPAN connection is disabled.
Warning: No WPAN connection is allowed unless the memory mode is disabled.
