Immersion Input Matrix Wiring Questions
mbasile35:
Hey guys
I've got a few leads on an single board style Immersion FFB PCB so I want to get my cabinet ready for wiring the input matrix and I have a few questions. My first one is about the diodes that wire in series with the pushbutton switch. If I wanted to make a small pcb with all of the diodes in a remote location So that I didnt have to solder diodes directly to the switches...would that work? Something like this:
My next question has to do with wiring a Happ 4 speed shifter to the matrix. With one of the "gear" switches always closed, will that interfere with the matrix? Also will that interfere with any emulators and if so do you guys have any ways to work around this? That's it for now but as I go through this I'm sure I'll have a few more questions and I'll bring them up here. Thanks Guys!

You're still around and working on your cab!
Definitely put all the diodes on another board instead of on the switches.
It will make wiring simpler and easier to understand.
Not sure how much soldering you do, but I'd use a blank proto-board with a cable running to the immersion pcb and a row of screw terminals along one edge to wire buttons to.
The same thing could be done with just wiring, but wouldn't look as neat or be as reliable.
My brain is done for the day, so I haven't checked your diagram for errors or anything.
Pretty sure the happ shifter has 4 switches. Are you sure you don't have the ketz one?
Please post pics if unsure.

Oh yeah slowly but surely I do little things here and there and every once in a while I'll knock out a few big things at once. This just happens to be one of those times.
That was my original thought to use a perf board and screw terminals...If it works well I may end of looking into getting an actual custom pcb made with headers to match the Immersion board but we'll see. I'm fairly certain the way I've draw it should work, just wanted a second or third opinion. And I'm assuming it's a Happ 4 speed shifter but could be wrong. It's off of a Cruisin' control panel. I'll get some pics tomorrow. I'm thinking if those four switches make up the same "sense" column (if that makes any sense...no pun intended) then i should be fine.
I also wasn't sure about the diodes. I'm guessing any old diode will work but just in case...I have a bunch of these laying around: http://www.mouser.com/ProductDetail/Vishay-Semiconductors/1N5817-E3-73/?qs=sGAEpiMZZMtQ8nqTKtFS%2fJkHNs4hgXaDYEhDurilN70%3d
Will that do the trick?
Thanks again
Mike

I've asked those wiser than me what model diodes would be correct for this type of application and have never been able to get an answer other than "any", so you should be fine.

It seems with pinball machines - if you need a "diode" for blocking purposes, the 1N4004 is used just about everywhere. Whole banks of the damn things.
