FIXED!!! Pole Position wheel/opto to Mini-Pac
(1/5) > >>
Texasmame:
NOTE:  Go to final two posts for fix for this problem.

Trying to hook up a PP wheel and opto to finish my cab.  From what I gathered on a google, you can't go directly from the pins - you must hack the PCB at certain points?  Is this correct?

If you're looking at the back of the opto, left to right, I'm thinking the pinout is:

input, 5v, gnd, input

Tried hooking up the spinner output of the Mini in that order - nothing.  Did I miss something or do you have to hack something and bypass that resistor, for example. . .

TIA,
John in TX

This thread has some good info for mouse hacks but nothing on the MINI.

And this one is close, too, but Gearhead took his pics off his site:

Right now, I've got the wires hooked up as shown in the labeled pic in that thread and I get nothing.   :'(  Wondering if this has to do with the signal going "high" or whatever tech mumbo jumbo that is.  Bah.

Running Win98SE but that shouldn't matter as the Mini can handle the two inputs at once.  Also have a mouse hooked up to the computer, if that matters.  Mouse and trac still working - steering dead.

I successfully hooked a Pole wheel up to an Opti-Wiz without any hacking or anything, I wonder if it had a different optic board from yours, or if the Opti-Wiz can handle "Active High" signals better than the Mini.

Hmm.. seems like I remember there being an Active High/Active Low jumper on the Opti-Pac, is there one on the Mini-Pac?
Kremmit:
Poop.  I sold the particular Pole wheel that I used previously.  I just tried to hook up tho only other loose one I've got, and all I get is the mouse cursor jitters. 

Edit-  nevermind, it's working fine now, must've been operator error. :dunno

My optic is the exact same one in the other thread you linked up, this one here:



The pinout labeled on the pic is the one I'm using, hooked to an Opti-Wiz.  I have not done any of the mods reccomended in that thread, it's exactly the way I pulled it off the Pole machine.

BTW, Tex, I also tried it out with one of my mouse hacks, and it works fine!  So if you've still got one of those unused, that should take care of you if your MiniPac can't be beat into working- although I'm surprised it doesn't- I really thought these Atari optics were pretty basic- nothing but the optics and one resistor on the pcb.

In regards to your first post - no jumper on the MINI.

Yeah, it the same opto - an Atari 80 - just the one resistor.  Even if I have the two x wires backwards, I should still get *something* or am I off base on that?

Also, due to my rotating panel, I'd like to do the mouse hack as a last resort as I would have to take the entire panel off again to run that one wire.  :(  I mean, the MINI *should* work fine here. . .
