6.4.4 Configuring the CLV with AutoSetup
AutoSetup enables the reading and code configurations of the CLV to be adapted automat-
ically to the application at hand. The following conditions must be fulfilled with regard to this:
• one bar code (code type, code length)
• fixed reading distance
• conveyor belt off (static reading)
The CLV determines the code type, code length and the most favorable scanning rate for
the bar code presented. This takes place in Free Running mode. Once AutoSetup has been
completed successfully, the CLV copies the parameter values determined to its parameter
set.
All other code types and code lengths are then disabled. If AutoSetup was not
completed successfully, the parameter set is not changed. The CLV does not read a
Pharmacode or any EAN/UPC types in AutoSetup. It does not respond to an external reading
pulse.
AutoSetup can be activated in three different ways in the CLV:
• via the user interface of CLV Setup
• by presenting profile bar code no. 10 (on the card supplied) to the optical interface
(reading window).
See Chapter 10.5.1 Activating AutoSetup with a profile bar code,
Page 10-17.
• via a command string (via the serial interface). See Chapter 10.6 Configuring the CLV
with command strings, Page 10-22.
While AutoSetup is running, the CLV outputs the step-by-step changes made to the
parameter values in the search mode and the determined diagnosis data via the terminal
