CLV 41x Bar Code Scanner
7. Function of the LEDs
The LED function indicators
7
are located on the rear, narrow side of the device (
Fig. 1
).
LED
Color
Function
Device Ready
green
Indicates that the the CLV is ready (Reading mode). Lights up when the device is switched on, after
the self-test has been successfully completed and when the wait time for teach-in mode has expired.
The LED extinguishes when the device is switched to a different operating mode.
Result
green
Function depends on the operating mode of the scanner:
•
In Reading Mode or Teach-in Mode, the LED indicates a successful read (good read).
If the match code comparison is activated, it lights up if the bar code read matches the specified
match code(s).
The LED lights up constantly until the start of the next reading pulse
•
In Percentage Evaluation with 100 scans per reading interval, the LED indicates the trend in the
read quality as follows:
LED off
good read rate < 30%
LED blinks (frequency 2 Hz)
good read rate 30%...70%
LED blinks (frequency 5 Hz)
good read rate 70% ... 90%
LED lights up constantly
good read rate > 90%
•
The LED lights up briefly when set to AutoSetup before it starts to scan the presented bar code
Laser On
green
Lights up when the laser diode is activated for reading the bar code.
The laser diode is activated and deactivated by the reading pulse.
The laser diode is activated constantly in Percentage Evaluation and Free-running modes.
In Reflector Polling pulse mode, it is activated in accordance with the scanning frequency at every
20th scan (LED flickers).
The scan line(s) are dimmed (with red-light scanner only)
Data
yellow
Flickers when the CLV is transferring data to the host on the serial data interface
