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. |

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? Scott Edit: Second possibility if you also want a 5-axis analog + 24 button matrix encoder. http://www.opencockpits.com/catalog/axes-card-p-55.html?cPath=21_36 |

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: http://www.allelectronics.com/make-a-store/item/KP-12/12-BUTTON-KEYPAD/1.html It has one common contact and a contact for each button, it is not set up on a matrix. |
