Visual Indicators - Metrologic MS7120 Series Installation And User Manual

Visual Indicators

There are a red LED and a green LED on the head of the Orbit MS7120.
When the scanner is on, the flashing or stationary activity of the LEDs
indicates the status of the current scan and the scanner.
No Red or Green LED
The LEDs will not be illuminated if the scanner is not receiving
power from the host or transformer.
Steady Green
When the laser is active, the green LED is illuminated. The green
LED will remain illuminated until the laser is deactivated.
During the power save mode, the laser will turn on and turn off.
During this period, the green LED remains illuminated.
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.
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.
Steady Green and Flashing Red
This indicates the scanner is in program mode. A razzberry tone
indicates that an invalid bar code has been scanned in this mode.
Steady Red, Green off
This indicates the scanner may be waiting for communication from
the host.
