Sleep Mode
After the scanner has been inactive for a period of time, the laser automatically turns
off; after some more time, the motor turns off and the scanner enters “sleep mode,”
indicated by the blue status LED blinking once a second. To wake up the unit, simply
present an object close to the scanner window, or press the push button.
Note: The scanner includes a motion sensor that detects activity in front of the scan
window. The detecting distance is up to about 50mm (2 inches) from the scan
window, depending on ambient light.
Controlling the Scanner from a POS System
The scanner can be controlled from the POS system via the RS-232C interface. Control
can be accomplished by transmitting the following single-byte com- mands to the
scanner. The default settings for the commands are as follows:
