INDICATORS
Visual
The scanner has blue and white LED
indicators on either side of the button on the
top of the unit. When the scanner is on, the
intensity of the LED and the flashing or
stationary activity of the LEDs, indicates the
status of the current scan and the diagnostic
scanner.
No LEDs are Illuminated
The LEDs will not be illuminated if the scanner is not receiving power from the
host or transformer.
Steady Low Intensity Blue
The scanner is in stand-by mode. Present a bar code to the scanner and the
blue LED will switch to a high intensity blue when the IR detects the object.
Steady High Intensity Blue
The high intensity blue LED is illuminated when the scanner is active and
attempting to decode a bar code.
Single White Flash
When the scanner successfully reads a bar code the unit will beep once and
the white LED will flash once indicating data has been transmitted
successfully. The blue LED will return to the low intensity state if no other
objects are presented in the active scan area.
If the scanner does not beep once and the white light does not flash, then the
bar code has not been successfully read.
Steady White
When the scanner successfully reads a bar code, it will beep once and the
white LED will turn on indicating data is being transmitted.
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.
Alternating Flashing of Blue and White
This indicates the scanner is in configuration mode. A short razzberry tone
indicates that an invalid bar code has been scanned while in this mode.
