Visual Indicators - extronics iSCAN100 Operating Manual

The iSCAN100 has three LED indicators (green, red and yellow) located on the
head of the scanner. The MS9520 has two LED indicators (green and red) located
on the head of the scanner. When the scanner is on, the flashing or stationary
activity of the LEDs indicates the status of the current scan and the scanner.
Green & red LED's off
The LEDs will not be illuminated if the scanner is not receiving power from
the host or transformer. The scanner is stand-by mode, and CodeGate
enabled. Present a bar code to the scanner and the green LED will turn on
when the laser turns on.
Steady Green
When the laser is active, the green LED is illuminated. The green LED will
remain illuminated until the laser is deactivated. (Default Mode Only)
Steady Green and Single Red Flash
When the scanner successfully reads a bar code, the red LED will flash and the
scanner will beep once. If the red LED does not flash or the scanner does not
beep once, then the bar code has not been successfully read.
(Default Mode Only)
Steady Green and Steady Red
After a successful scan, the scanner transmits the data to the host device. Some
communication modes require that the host inform the scanner when data is ready
to be received. If the host is not ready to accept the information, the scanner's red
LED will remain on until the data can be transmitted.
Alternating Flashing of Green and Red
This indicates the scanner is program mode. A raspberry tone indicates that an
invalid bar code has been scanned while in this mode.
The scanner needs to have a Flash ROM upgrade if the alternating flashing of the
red and green LEDs occurs during start-up and is accompanied by three beeps.
Steady Red, Green off
This indicates the scanner may be waiting for communication from the host.
