1.1 POWER

Connect the interface cable between the scanner and your computer.
If using the RS-232 cable, you must join the power supply cord to power up the
scanner.
The scanner will respond with one long beep (high tone) and its LED indicator will
become solid red and go off quickly.

1.2 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 using a low
baud rate or waiting for handshake signal (flow control). With the 4 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.
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 power adaptor to the RS-232
cable is removed or other interface cable is disconnected!
