End of Configuration
This activates the default values shown in the left upper corner of the table
(baud rate, number of data bits ...).
4. Scan one bar code and check its transmission to the PC. For the meaning
of the tones and melodies please read chapter 4.4 of the "User Guide".
Examples:
•
descending melody during scanning: Battery empty soon (after the next 2 scans).
•
Ascending melody connecting the scanner to the charger: Battery was flat, former
registration to a base station lost, please register again.
Please note:
-
The Ex-protected base station provides only the data terminals mentioned in chapter 7:
"Terminals".
-
If scanner and base station are configured to wait for an acknowledge signal from the PC,
this will take several seconds for each scanning procedure. (See chapter 5 of the "User
Guide".)
-
In PS/2 mode the base station does not answer to the PC like a keyboard, in order not to
disturb the communication between the PC and a keyboard in parallel to the base station.
This might make the PC switch off the PS/2 lines. In this case please switch a keyboard
or a PS/2 simulator in parallel inside of the safe area using our keyboard wedge KS-20 or
modify the BIOS configuration ("Stand Alone PC" e.g.).
-
After "misunderstandings" between scanner and PC in PS/2 mode please scan the
"default settings" (barcode see folder), scan some product bar codes and go the PS/2
mode again. Sometimes even several scans of the code "end of configuration" may help.
Correct connections are not enough to ensure correct data transmission. Please see chapter 7
"Terminals" for data types and values. Configuration of the scanner is described in the
"programming Guide" and the "User Guide". Factory settings see page 4 of the folder e.g.
Please note,
•
that the antenna cannot be screwed off the base station !!
•
that the long range version of the scanner needs at least 30 cm distance from a
bar code, even for registration to the base station.
•
that bar code labels may shine, even the one on the base station. In this case
incline the laser beam.
•
If scanners refuse registration to base stations: Charge the battery completely. If
this does not help: scan "End of configuration" from any configuration procedure.
