CNC Ports pins 12 or 14

[Munra]

I have noticed that hypertherm cutters use a 14 pin cnc connector and the everlast products (Atleast in the IOM) uses a 12 pin.

Why the difference? Assuming it doesn't really matter but was curious.

Thanks.

Hypertherm did have them when we first came out with ours for one, or at least when we started planning. But I would assume theirs is proprietary anyway.
