Pokeys57CNC Mach4 Charge Pump/Safety Circuit

Hi, I had a Mach3 setup before with an ESS - MB3 breakout board and had the spindle VFD and Stepper Drivers on a relay/safety circuit. (Charge Pump).

On the MB3 it was pretty simple as I just ran the CP to in Signal of a Relay - job done. If the PC went off then the Spindle/drives were cut off from the mains power.

Struggling with the Pokeys57CNC though and cannot seem to find an example anywhere.

As mentioned I simply want the CP to activate a relay when Mach4 connects to the Pokeys.

Could anyone help please?

thanks

Edit: I was actually hoping that you could link the Charge Pump up internally (assign pins) to the relays on the board (or SSR outputs). But can't see where I could do this either.
