i haven't got it to work yet but this is what i'm figuring.

as an example, "key 1" requires pins 1 and 5 (pin 8 being the common ground).  from the terminal block, i'll pull 1 and 5 and wire them to whatever input the ipac is programmed for button 1.

for "key 2", pins 1 and 6 are required (8 being the common).  pull 1 and 6 from the terminal block to ipacs number "2" input

ah crap, i'm having a brain fart.  more testing when i get home, i don't think the above will work.

If you're building a matrix encoder from scratch, youll need to design a circuit with a dozen AND gates to make your keypad work with an I-Pac.

I PM'd you a link on May 29th for a matrix encoder board used by some flight sim guys.

http://www.opencockpits.com/catalog/usbkeys-card-p-53.html?cPath=21_35

This is the lowest cost programmable matrix encoder that I've seen.

Has anyone actually used this model?

Anyone have another recommendation?

Edit: Second possibility if you also want a 5-axis analog + 24 button matrix encoder.

24 buttons is perfect, each keypad has 12.  looks like I didn't fully think this thru.  thanks for the input, I'll look  lost at that link

Here is the keypad I used for the digital lock on my workshed:

It has one common contact and a contact for each button, it is not set up on a matrix.

thank you guys, looks like i'll get two new keypads.  back to the drawing board and a restart on my panel unless these keypads fit magically into what i already have made :)

thank god i didn't start the artwork yet
