My foldable plasma table

I have now recived my THCAD card. My thoughts is to mound thad card on the plasma to hold all the high voltages on the plasma. Is this how you should recomend me doing it? I think that i have some aluminiumbox that i can mount it in.

Hi! I have bought a new plasma (Herocut 55x) now with pilot arc and should use that instead of the HF-start machine that i have used. 
Can the THCAD-10 card work without any modifications to this card?

In the attached picture i have  questiions how i should connect the lower plug. On my old plasma i just have a  relay that drives connects/disconnects the torch button. Now four cables?


Can i add the THCAD card inside the main unit or should i avoid that and put it separatly.
I see that i need to read up how to connect the THCAD card. i don't yet understand these ports and how they work. 

FOUT+ Frequency out +
FOUT- Frequency out - 
FREF+ Reference frequency
FREF- Reference frequency
 

You don't need FREF so if you use 4 pair CAT5. I would wire it:

one pair +5V (use pair for lower voltage drop)
two pair GND (use 2 pairs for lower voltage drop)
one pair FOUT+ and FOUT-

Thanks! Do you know how the arc starting signal from the output works? Sould i wire it some where or is that unnecessary when using THCAD?
