Appendix
 Upload the parameter set with the CLV Setup program and check whether the new
parameters are relevant for configuring the CLV for the current reading application. If
necessary, change the parameter values and download the parameter set to the CLV
again. Save the new parameter set as a configuration file in CLV Setup and print it out
as profile bar codes for archiving purposes.
See also Chapter 10.4.10 Dealing with unknown parameters, Page 10-15.
10.10.2 Downloading the parameter set
To download the parameter set, you must connect a PC running the CLV Setup software to
the replacement device. The parameter set of the CLV that is to be replaced must be
available as a configuration file in CLV Setup, otherwise the device must be configured from
scratch.
1. Switch off the power supply of the CDB 420 or CDM 420 connection module (of the
CLV).
2. Disconnect the CLV connector from the CDB 420 or CDM 420.
3. Remove the CLV from the bracket.
Before doing so, mark the position and alignment on the bracket/station.
4. Install, align, and connect the replacement device.
5. Connect the PC to the terminal interface of the CLV using a 3-core RS 232 data cable
(null modem cable) (CDB 420 or CDM 420: connect the PC to the internal, 9-pin "Aux"
plug,
see Chapter 5.5.6 Connecting the PC, Page 5-7.).
6. Switch on the power supply to the CDB 420 or CDM 420.
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.
7. Switch on your PC and start Windows.
8. Start "CLV Setup".
If the communication parameters on the PC and CLV are identical, CLV Setup uploads
the parameter set from the CLV and displays the values on the tabs.
9. Open the archived parameter set as a configuration file "*.scl" in CLV Setup and
download it to the CLV.
10. Confirm the dialog box by choosing the TEMPORARY storage option.
11. Check whether the CLV reads the bar codes correctly.
Correct the parameter settings if necessary.
12. Finally, download the tested parameter set to the CLV and save it with the PERMANENT
storage option.
The parameter set is transferred permanently to the replacement device.
13. Save the modified parameter set as a new configuration file in CLV Setup.
Troubleshooting
If the software version on the replacement (new) device is older than the version on the old
device (e. g. new device is from warehouse stock), the parameter set transferred may
contain coded parameters or parameter values that cannot be interpreted by the older
software. The new device, however, outputs an error message in CLV Setup for each of
these parameters/parameter values when the parameter set is downloaded.
 Check whether all of the parameter settings used are necessary to configure the CLV
for the current reading application. If necessary, replace the software version in the new
device.
