Notes:

1. Resolution selected via adjustable DIP switch, pre-set to 5120 PPR. All resolutions are listed as pre-quadrature, meaning the final number of counts is PPR x 4.

2. Some stepper motors may leak a magnetic field causing the AMT index pulse to not function properly (non-magnetic version available with 20 pulses per revolution).
