8. Backlight
The use of suitable lighting is an important factor for parts to be detected on the platform and
their orientation. All the Asycubes can be equipped with an integrated backlight. This chapter
summarises the different possibilities to activate the backlight as well as how to configure its
intensity.
8.1. Activation
There are two ways to activate the backlight illumination and to synchronise it with the image
acquisition (see Table 8-1).
Software commands:
a.) Command to switch ON and then command to
switch OFF
b.) Flashing-mode
Hardware connection:
Using the backlight synchronisation input. The illumination time
corresponds to the impulse length.
Table 8-1: Backlight activation modes
When using both activation methods, the backlight will be ON if the command OR the signal
is activated.
Note that using a camera that is able to control the backlight of the Asycube (Method 2 –
Hardware connection) is more reliable in terms of timing than using software commands to
activate the Asycube backlight and then commands to a camera for image acquisition.
For more information on the commands related to the activation of the backlight, please refer
to the programming guide for your Asycube.
For more information on the electrical interface and connector reference of the backlight
synchronisation, please refer to the operating manual for your Asycube.
NOTE:
The backlight is optional and has to be ordered with your Asycube, as well as its colour.
