Verifier LED Indicators
Five LED indicators are included on the verifier’s back panel.
Power/Sync
LED
This LED is green whenever power is applied to the
verifier. Upon receipt of any sync input (hardware or
serial communications) the LED blinks yellow for
approximately 100 milliseconds.
Calibration
LED
This yellow LED indicates calibration status. Refer to
the SV Series Operator’s Guide for more information.
Read LED
This LED is green whenever a bar code is being
decoded.
Indicator LED
1 and 2
These two green LED’s are user programmable exactly
like the five output ports. Their functions are intended
for use as indicators for specific analysis results.
A common example is LED 1 programmed to light in
latch mode whenever a symbol quality error is detected,
while LED 2 is programmed to light in latch mode
whenever a No Read error is detected. Refer to the SV
Series Operator’s Guide for more information.
