Operation
Triggering the reading pulse via the Terminal Emulator:
In the default setting the "Sensor" switching input is the (external) trigger source of the rea-
ding 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 temporarily
in the CLV.
1. Choose DEVICE CONFIGURATION tab.
2. In the READING TRIGGER SOURCE section click the SERIAL INTERFACE option.
3. Perform a download to the CLV.
To do so, click the SERIAL INTERFACE option again with the right mouse button and choose
D
OWNLOAD PARAMETER in the context menu.
CLV-Setup copies the parameter temporary to the CLV.
The serial interface has been activated as the trigger source of the reading pulse and
is ready to receive appropriate commands (until the CLV is switched off).
4. Click in the toolbar.
The Terminal Emulator window is then displayed.
The CLV is in the Reading mode.
5. Click the SW-TRIGGER ON button or press [F7].
CLV-Setup sends a start command to the CLV.
The "Sensor" LED lights up and the red scan line appears.
6. Present the bar code pattern from Fig. 6-1, Page 6-3 to the CLV.
7. Click the SW-TRIGGER OFF button or press [F8].
CLV-Setup sends a stop command to the CLV. The "Sensor" LED is extinguished. The
CLV switches off the laser diode. The CLV displays the reading result in the output win
-
dow of the Terminal Emulator. The "Read Result" LED lights up for a duration of 100 ms
(default setting).
6.5.2 Percentage evaluation
In the Percentage evaluation mode, the quality of the reading function is assessed (no con-
veyor movement).
The CLV performs 100 scans in the free running mode and evaluates the reading quality. It
outputs the reading result continuously every 2 s via the terminal interface. The reading
results can be displayed in the Terminal Emulator of CLV-Setup. The standard decoder has
to be set temporarily for the percentage evaluation.
The "Result 1" to "Result 4" switching
outputs do not become live in the Percentage evaluation mode.
The Percentage evaluation mode can be called up by choosing VIEW in the menu bar, as a
device function via CLV
480 (interactively), or via the Terminal Emulator.
Line scanner with oscillating mirror:
In the Percent Evaluation mode, the CLV behaves in the following manner:
– in "Oscillating" mode (basic setting: oscillating with a fixed amplitude), the CLV shuts off
oscillation and positions the scan line under the angle CW
= 50 (corresponds to a
deflection angle below 105
°). This position cannot be altered.
– in "One-Shot" mode, the CLV positions the scan line under the angle CW = 50 as well.
– in ”Fixed position” mode, however the scan line’s selected position remains unchanged.
1. Choose the CODE CONFIGURATION tab.
2. In the DECODER section, choose STANDARD.
3. Perform a download to the CLV.
