EMCO Compact 5 CNC 6 station turret


Hi I am converting my emco compact 5 cnc to masso and have the x and z figured out but am confused on the tool changer.

the tool changer only has 2 wires no signal wires of any sort. I don't mind converting it to a nema 11 stepper but ill be in the same boat with S+ S- and D+ D- and no input wires

what can I do here?
