V ISUAL I NDICATORS
The MS9544 has three LED indicators (blue, white and yellow) located on the
head of the scanner. The MS9524 has two LED indicators (blue and white)
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.
Blue, White & Yellow (MS9544’s Only) LEDs are 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 ® is enabled.
Present a bar code to the scanner and the blue LED will turn
on when the laser turns on.
Steady Yellow (MS9544’s Only)
The CodeGate button is not active. If a bar code is in the
scan field, the laser will turn on. The bar code will be
decoded and transmitted to the host automatically.
Steady Blue
When the laser is active, the blue LED is illuminated. The
blue LED will remain illuminated until the laser is
deactivated. (Default Mode Only)
Steady Blue and Single White Flash
When the scanner successfully reads and transmits a bar
code, the white LED will flash and the scanner will beep
once. If the white LED does not flash or the scanner does
not beep once, then the bar code has not been successfully
read and/or transmitted.
(Default Mode Only)
Steady Blue and Steady White
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 white LED will remain on until the data can be
transmitted.
