10.5 Configuring the CLV with profile bar codes
10.5.1 Activating AutoSetup with a profile bar code
Profile programming uses special bar codes to parameterize the CLV via the optical
interface (reading window) and to initiate device functions. The profile bar codes contain
encoded parameter values or commands.
It is not necessary to connect a PC to the CLV in order to carry out profile programming.
Profile bar code no. 10 on the card supplied (no. 8 008 085) starts and ends AutoSetup. It
can be presented to the CLV either immediately after the power supply has been switched
on, during the wait time in the Free Running mode or during a reading pulse in the Reading
mode.
Preparing AutoSetup
1. AutoSetup overwrites important values in the current parameter set of the CLV.
If the CLV has already been configured for a particular application, it is advisable to save
the existing parameter set as a configuration file "*.scl" in CLV Setup.
(See Chapter 6.4.1 Configuring CLV with the user interface of CLV Setup, Page 6-4.)
2. Have card no. 8 008 085 with the 12 preprinted profile bar codes ready or print the
bar codes as PDF file from the CD-ROM („Manuals & Software“). To do so, select the
“Programming Profile Bar Codes“ folder in the list on the top left of the start page.
Running AutoSetup after switching on the power supply
1. Fold the card with the profile bar codes in such a way that only profile bar code no. 10
is visible.
2. Switch on the power supply of the CDB 420 or CDM 420 connection module (of the
CLV).
The CLV confirms that the self-test has been completed successfully by outputting a
tone via the beeper. The "Device Ready" LED lights up. It then switches to the Free
Running mode for 5 seconds. The red scan line appears when the "Laser On" LED lights
up.
3. Present profile bar code no. 10 within 5 seconds.
The CLV confirms that AutoSetup has started by outputting a tone via the beeper. It
temporarily activates the standard decoder. The "Device Ready" LED is extinguished.
4. Present the application-specific bar code 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 (
Fig. 4-7, Page 4-5). Leave the bar code in this position.
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). It overwrites the appropriate parameter values in the current parameter set in
the RAM and stores these permanently in the EEPROM. The CLV returns to Reading
mode. The "Device Ready" LED lights up.
The CLV only evaluates the presented code type and length the next time a bar code
is read.
