Choosing the standard decoder:
4.
Choose the C

C
ONFIGURATION
tab.
5.
Click the S
TANDARD
option in the D

section.
6.
Download the settings to the CLX by clicking
on the toolbar.
The D
OWNLOAD
P
ARAMETERS
dialog box is then displayed.
7.
Confirm the dialog box by choosing T
EMPORARY
.
The CLX then operates with the standard decoder.
Activating Percentage Evaluation mode:
8.
From the V

E
VALUATION
.
The dialog box for entering the distance configuration appears.
9.
Click the relevant distance configuration for the reading distance:
– with autofocus mode the distance configuration no. 1
– with event-controlled dynamic focus control the distance configuration that matches
the reading distance of the object (default: no. 1, focus position F = 1 200 mm).
10. Confirm the dialog box with OK.
The Terminal Emulator is launched and displays the reading result continuously (see

during each of the subsequent steps!
Fine adjustment:
11. Align the CLX in such a way that the angle between the scan line and the bars on the
bar code CLX is almost 90
°
.
12. To avoid interfering reflections, align the CLX reading window in parallel to the bar code
surface. Consider the positioning of the CLX in relation to the convoyer direction (see
13. If necessary, align the intersecting point of folded scanline exactly with the bar code.
14. Move objects carrying bar codes into the CLX reading field manually under realistic
conditions and check the reading result. If the objects are aligned randomly, or if the bar
code is located at different positions (angles), ensure that the limit values of the
permissible reading angles are not exceeded.
15. Adjust the CLX in such a way that the good read rate is between
70 ... 100 %
.
With event-controlled dynamic focus control, for each defined reading range (distance
configuration), check the selected focus position and correct the parameter settings if

).
16. Tighten the screws on the CLX.
The CLX is aligned with the bar code.
