Pinout for the AUX connector
The pinout for the AUX connector is described in the table below:
The AUX is default a 1 Vpp (Volt peak-to-peak) input with a max frequency of 300 Hz. It has a
programmable high gain mode with a maximum input signal of 300 mVpp (millivolt peak-to-peak).
The inputs are differential. For a single ended sensor signal, the pin 1 (input -) should be connected to
the GND of the sensor.
