I've had odd results with windows either not seeing new hardware or loading drivers correctly first time the PC boots



Do you have a multimeter to check the 5V supply to the rotory encoder ?

once you confirm the 5V supply is correct


measure the voltage between the common 0V and A output

depending on its position when stopped you will either have 0V or +5V


while your rotating the knob the output will switch between 0 & 5V (50% of the time at 0V and 50% at 5V)


( see the Quadrature outputs here :-

https://en.wikipedia.org/wiki/Incremental_encoder )



your meter will read the average 2.5V

you should see the same measuring between 0V and the B output

Hey john do you by chance know what the bios settings should be for the 2nd printer port pci card ? there are choices ecp/epp and another one I dont know off hand? what should the 2nd priner port card be set to in this setting? I ask because I think there is a problem with either windows and the drivers or the card it self and the reason is I set all my settings and the selector switch works but when I turn off the computer and turn it back on it does not work I have to go back and forth resetting the settings and I think it is the computer resetting itself do you have nay ideas?
