Faced such a problem. I’m trying to set up an analog input using vbox v2 75V100x2 j, a week 2 ago everything worked well, but now when nothing is connected to the ADC it gives out 2.6-3.3 on all channels, I checked it all with a multimeter, indeed voltage is taken from somewhere on these pins. Help people kind, can who faced such problem. At the same time, everything inside the program will display correctly. Indeed, such voltages are present.You are here

Sometimes the extensions cables do not have a correct color code. When this happens I take a power source at 5Volts and a multimeter. I connect +5V to one throttle wire, the power GND to other, and I measure voltage between GND and the third wire. If I measure 0.82 Volts (approximately) then when turning full throttle, I measure 4.92 Volts. When the combination is not correct, you can measure constant values, or quickly changing ones. Change the wires until you get the correct pin out.
