IO extender in the back of the Gatekeeper-X
In order to connect a Gatekeeper-X with the Brivo controller an IO extender is necessary.
The IO pins as they come in the back of the Gatekeeper have an output voltage of 3.3V and can not be used directly.
The IO extender shifts the Wiegand signal generated by CortexFramework to 5V.
The IO extender has to be placed in the back of the Gatekeeper.
