To use any of the optically isolated inputs (10 to 13) on the FP-48 they have to be provided with between +5 and +12 volts (+) connection and then they can be switched ON and OFF by taking the (-) connection to GND (active low signal to Mach3).
Connect your red wire to +12 volts then connect your black wire to GND and the FP-48 on-board IO LED should illuminate. You then need to set-up your probe operation.
