interface in the form of a list. The list can be displayed, for example, in the terminal emulator
of CLV Setup. Once AutoSetup has been completed, appropriate error messages are output
for diagnosed malfunctions in the event of a no read.
Explanation
AutoSetup procedure
1.
Starting at 400 Hz, the CLV increases its scanning frequency to 1,200 Hz in steps of
100 Hz. It evaluates the reading quality of 100 scans for each step.
2.
The CLV performs verification reads +/– 50 Hz around the scanning frequency with the
highest reading quality.
3.
It then copies the optimum scanning frequency, the code type and code length to its
parameter set.
Activating AutoSetup via the user interface of CLV Setup
In CLV Setup, AutoSetup can be started by choosing the appropriate menu path, via the
terminal emulator or as an executable device function (interactively). Due to the better
display of the progressing procedure, we recommend starting AutoSetup via the terminal
emulator.
Preparing AutoSetup:
1.
Switch on the power supply of the CDB 420 or CDM 420 connection module (of the
CLV).
After the CLV has started, it emits a tone to indicate that the self-test was successful.
After a short while, it outputs two consecutive tones to indicate that it has switched to
reading mode. The "Device Ready" LED lights up.
2.
Upload the current parameter set from the CLV with CLV Setup (the parameter set
initially contains the factory default settings).
CLV Setup displays the current values on the tabs.
3.
AutoSetup overwrites important values in the current parameter set of the CLV.
Save the existing parameter set as a configuration file "*.scl" in CLV Setup before you
change the parameter settings.

Chapter 6.4.1 Configuring CLV with the user
interface of CLV Setup, Page 6-4
.
Performing AutoSetup:
1.
Click
in the toolbar.
The terminal emulator is launched. The CLV is in reading mode.
2.
Present the application-specific bar code to the CLV at the maximum reading distance
for the application. Note the limits of the CLV here.
See reading field diagrams in
Chapter 10.2 Specification diagrams, Page 10-1
.
To prevent surface reflections, rotate the bar code towards the CLV approximately 15
°
away from the vertical axis.

.
The CLV cancels reading mode. The "Device Ready" LED is extinguished.
The CLV then starts AutoSetup.
The red scan line appears when the "Laser On" LED lights up.
4.
The CLV then runs AutoSetup and continuously displays the changes to the parameter
values in the terminal emulator (
5.
The CLV confirms that AutoSetup has been completed successfully by outputting two
consecutive tones via the beeper and activating the "Result" LED for 100 ms (default
setting). To begin with, it only overwrites the appropriate parameter values in the RAM.
The CLV returns to reading mode. The "Device Ready" LED lights up. The R
