IPAC 4 and Admin Buttons

Hello!

First post and BYOAC Newbie but taking on the adventure!

My question is what about using this to setup admin buttons with the IPAC4:

I know that it is SUPPOSED to be for the keywiz, but why wouldn't it work to press the p1 button and then the button for the enter, pause, esc, etc...

If I get what you are asking: The I-PAC 4 has a built-in "shift" feature.  No additional cables are necessary.

Just use the included WinIPAC software to program the I-PAC. You can select your "shift" button, and assign a second keystroke to every other button.

Won't work because the I-PAC sends shift codes on key release, not key down like the KeyWiz.

You can do what you want with a resistor and capacitor (per button).

See http://www.ultimarc.com/extra_shift.html and the section labelled "I-PAC STEALTH MODE" on this page http://www.mameworld.net/tigerheli/encoder/shiftkeys.htm
Tiger-Heli:
Bigger question is why would you need it.

That circuit is designed for the KeyWiz so you can send a shifted input with a single button press.

This is useful if you are using all your 32 inputs and need additional shifted inputs for coin and start.

It would make sense for an I-PAC/2.

Do you really have 56 action inputs and not enough remaining inputs for admin functions that you need one-press shifted admin buttons on your CP?

Thank you for the information.

It isn't that I have that many buttons, but I was just thinking of future expansion to 8 buttons per player instead of just 6.  To which I could leave those inputs open.

I think I am just going to use some of the extra locations for the admin buttons.  I do appreciate your help though.
