Triggering the reading pulse via the terminal emulator
In the default setting the "Sensor 1" switching input is the (external) trigger source of the
reading pulse. The reading pulse can also be triggered directly via the terminal emulator of
CLV-Setup for test purposes. To do so, a different trigger source must be selected tempora-
rily in the CLV.
1. Select the D
EVICE
C
ONFIGURATION
tab card.
2. Click on the E
DIT READING TRIGGER
command button.
The E
DIT READING TRIGGER
dialog box is opened.
3. Click on the S
ERIAL INTERFACE
radio button.
4. Confirm the dialog box with "OK".
5. Carry out the download to the CLV. To do so, click on in the toolbar.
The D
OWNLOAD PARAMETERS
dialog box is opened.
6. Confirm the dialog box with the saving option T
EMPORARY
.
The serial interface has been activated as the trigger source of the reading pulse and
is ready to receive appropriate commands.
7. Click on in the toolbar.
The terminal emulator dialog box is opened. The CLV is in the Reading mode.
8. Click on the SW-T
RIGGER ON
command button or press [F7].
CLV-Setup sends a start command to the CLV.
The "Laser On" LED lights up and the scan line appears.
9. Present the bar code pattern from Fig. 6-1, Page 6-3 to the CLV 450 respectively the
bar code pattern from Fig. 6-2, Page 6-4 to the CLV 451.
10. Click on the SW-T
RIGGER OFF
command button or press [F8].
CLV-Setup sends a stop command to the CLV.
The "Laser On" is extinguished. The CLV switches off the laser diode.
The CLV outputs an acoustic signal via the beeper to indicate that the reading result is
displayed in the window of the terminal emulator. The "Result" LED lights up for a dura-
tion of 100 ms (default setting).
6.5.2 Percentage evaluation
In the Percentage evaluation mode, the quality is assessed of the readings of bar codes
which are placed statically into the reading area of the CLV (no transport movement of the
object).
The CLV performs 100 scans in the Free-running mode and evaluates the reading quality.
It outputs the read results continuously every 2 s via the
terminal interface
. The read re-
sults can be displayed in the terminal emulator of CLV-Setup.
The standard decoder has to be set temporarily for the percentage evaluation.
The Percentage evaluation mode can be called up via V
IEW
in the menu bar or via the
terminal emulator.
Line scanner with oscillating mirror:
In the Percentage evaluation mode the CLV behaves in the following manner:
– in “Oscillating“ mode (default setting: oscillating with a fixed amplitude), the CLV shuts
off oscillation and positions the scan line under the angle CW = 50 (corresponding to
an angle of deflection of 105
°
). This position cannot be altered.
– in “One-Shot“ mode, the CLV also positions the scan line under the angle CW = 50.
– in “Set Position“ mode, the scan line’s selected position remains unchanged.
