I have 5 volts alternating at x1 or x2 on gnd.
this is what andi from ultimarc wrote to me.
"But the Arkanoid spinner might not be compatible. It needs to be a 2-channel quadrature design with active-low signal lines."
Do you think the spinner could not fit on the ipac?

I forgot that the Arkanoid spinner is an "active-high" device. :embarassed:
- Active-high and active-low devices have different voltage ranges for logic high and logic low.

An Opti-PAC has the option to use active-high devices.

Almost all optical controls are active-low, which means the outputs are actively pulled to zero volts, or left "open", depending on the position of the optical spoked wheel.
If your device is "Active High", it will pull the outputs to 5 volts, or leave "open" depending on the wheel position.
The Opti-PAC can be configured to handle Acrive-High devices using a simple software utility. Just click on the check-boxes for the inputs you need to be set to active-high.
