AT833
The following circuit shows a example implementation for the AT833 Module. This Module is available on request info@kk-t.de. Each pin and its functionality is described in the table below.
Please do not change the components and values. Ensure a stable +3.3V_Mesh supply with a minimum current delivery of 20 mA.
Please ensure that the capacitors are connected as close as possible to the controller.
| Pin | Description | Mandatory | Function | Use | Wiring |
| P0.03 | FIXTURE_IS_ON | Yes | Whenever this Pin is high the Vision Controller is in On State. If this Pin is low, the Vision Controller goes to sleep. If the fixture is in normal Operation (Power On) it should set this Pin to high. If the fixture is turned off, sleeping or in a wake up state this pin should be low. When the fixture wakes up due to the „MAIN_WAKEUP“ from the Vision Controller, make sure this Pin is still low! | High: Vision Controller normal operation Low: Vision Controller sleep mode | Pull Down (100K) |
| P0.02 | MAIN_WAKEUP | No | This Pin is used for signalling that the Vision Controller wants to communicate with the fixture. It is also used to wake up the main controller in order to communicate. This pin is pulled high as long the Vision Controller wants to communicate with the fixture. | This Pin is pulled high if communication is needed. Normal operation this pin is always high. | |
