Reading mode
Device Ready
Green
•
Lights up constantly
•
Extinguishes with new operating mode/function
Sensor
Green
•
Lights up if reading diode active
(The laser diode is activated/deactivated by the reading pulse)
•
Lights up constantly in Free-running mode, since the laser diode is constantly
active
Read Result
Green
LED is linked to the "Result 2" output and indicates the selected result status for the
defined pulse duration of the output.
•
Lights up after a successful read (Good Read)
•
Lights up if the match code comparison is active, the bar code read matches the
specified match code(s) and the corresponding result output is selected fo
r the
"Result 2" output

Behavior dependent on the reading quality:
•
Extinguishes if reading rate < 30 %
•
Blinks twice a second if reading rate 30 % to 70 %
•
Blinks five times a second if reading rate 70 % to 90 %
•
Lights up constantly if reading rate > 90 %
Adjusting mode Sensor
Green
•
Lights up constantly, since Free-running mode is active
Show RA-limits
Sensor
Green
•
Blinks bright/dark alternately, in the frequency with which the scan line is (partially)
masked out
