5.3.8 Optimizing image brightness
The set image brightness is sufficient in most cases. Due to differing material qualities
of the racks and the associated differing reflection behavior, however, it may be
necessary to adjust the image brightness.
Relevant for combined applications with single deep and double deep racks: The
image brightness and illumination time must be set high enough to achieve image
brightness which is sufficient even in double deep racks. However, the camera image
must not be too brightly lit in single deep racks.
1. Activate Maintenance user level.
2. If necessary, deactivate the Double deep parameter in the Rack Fine Positioning
area.
The device is in Single deep mode.
3. Open the Camera adjustment window.
4. How to set the image brightness in Single deep mode:
− In the Camera configuration area, set the Gain factor parameter
(recommendation: 1.0 – 2.0).
− In the Camera configuration area, set the Shutter time [µs] parameter
(recommendation: 80…200 µs).
For good image brightness, observe the edges of the positioning mark and any
total reflections of the background as decision-making criteria. With holes,
the dark circle must be clearly differentiated from the light background. With
reflectors, the light circle must be clearly differentiated from the dark background.
The illumination time cannot be set separately for single and double deep
5. In the Rack Fine Positioning area, activate the Double deep parameter.
The device is in Double deep mode.
6. Increase the Gain factor parameter in Double deep mode to a value which offers
sufficient image brightness for positioning marks in double deep racks. Do not set
values greater than 5 to prevent increased image noise. If higher values are
necessary, adjust the illumination time accordingly.
7. Check the settings in Single deep mode again. If necessary, reduce the Gain
factor parameter in Single deep mode.
8. Activate the Perform auto gain parameter in order to automatically set a suitable
image brightness using the Auto-gain assistant.
The device records a series of images and automatically sets the Gain factor
parameter. The Auto-gain assistant and continuous measurement are
automatically deactivated after they are successfully executed.
5.3.9 Setting up Ethernet interface
The device supports various communication protocols when using the Ethernet
interface. To set the communication protocol used in SOPASair:
1. Open the Interfaces window in SOPASair.
2. In the Ethernet mode area, set the communication protocol.
3. Also define the IP address and port used so that communication between the
controller and the device runs smoothly.
The device also offers the option of transmitting images via the file transfer protocol
(FTP). The respective destination address can also be set up in the Interfaces window.
