Question

Hi, I have a simple magnetic door sensor and a FMU 130.

How can I configure my gps to check if the sensor is open or close? I dont know if I have to use AIN or DIN, and I guess this kind of sensors, with only 2 wires, use GND and another input or output from the GPS

Hello.

It depends how your sensor is connected and what signal it gives on output. If it is simple sensor that is closing GND circuit, you could use DIN2/AIN1 input as ground sense:
