Function Description
Read Diagn (read diag‐
nosis)
Percentage evaluation: the product records images. The product uses
the current settings of the read properties to decode them. With the 0
to 100% bar graph, the product shows the read rate of the last 10%
(90% to 100%).
The bar graph display is activated in standard read mode.
Autofocus The product adjusts to the working distance. The product permanently
stores this working distance.
3.6 Acoustic status indicator
The beeper (buzzer) is located under the cover on the top of the product. The beeper
can be switched off.
In read mode, the beeper indicates a selectable event with a signal tone (default: event
= Good Read).
3.7 Function and use
The product localizes automated guided vehicles (AGVs) using 2D codes.
The product is mounted on the underside of the AGV. The 2D codes are attached in the
form of a grid on the floor. The individual 2D codes are numbered and contain position
information. The product detects and decodes 2D codes. The product uses the host
interface to send the read data, the additionally detected X- and Y-coordinates and the
angle of shift to a higher-level controller (e.g. PLC). Using this data, the AGV is localized
and repositioned by the controller.

5.2.2 Working range
The possible working range for reading is 70mm to 500mm. These values refer to
the reading of a Data Matrix code with a resolution of 0.7mm. The working distance is
measured starting from the housing edge.

The device uses the Auto Setup function to automatically set the focus position to the
working distance. The function can be executed in SOPAS ET.
The focus position is valid for one working distance. The device does not perform auto‐
matic tracking (auto focus) if, for example, the working distance changes significantly.
NOTE
After successful calibration, do not change the working distance of the device and the
reading distance set in SOPAS ET.
If these settings are changed, the device must be recalibrated.
The set working distance effects the speed of the AGV and the size of the field of view
depending on the mounting alignment and the 2D codes used, see "Typical reference
values during operation", page 47.
5.2.3 Mounting angle
Important information
NOTE
If problems with reflections occur, use a polarizing filter (part number: 2088228), see
"Accessories", page 46.
NOTE
Use the latest version of the SOPASET configuration software.
Versions older than SOPASET Version 2018.04 are not compatible with the device.
Adjusting the mounting angle
Align the device at a 90° angle to the surface so that the beta (β) and gamma (γ)
angles are set to exactly 0°. Check the beta (β) and gamma (γ) angles in SOPASET, see
"Configuring the product manually", page 31.
Adjustment of the alpha angle (α) is only relevant when using single 2D codes (not a
multicode label). Adjust the alpha (α) angle to change the coordinate system of the field
of view, see "Configuring the product manually", page 31.
