Just got Immersion FFB!

[Hadeys]

Hey all,
Just picked up an Immersion force feedback board on Ebay. I'm pretty excited to give it a shot!  Currently my driving cab has been using the Logitech hack, so would it be necessary to change the 100k pot back to a 5k pot? What is the recommended power supply?  Also, where do you connect the steering pot?

Thanks much,
Daniel

(some comments about the power supply in the last post)

If it's the one I was eyeing on ebay recently, it only has inputs for two axis like the one I already have.
There is a way to wire both pedals together so they can be connected to one axis.
It's been on my to-do list forever to post the diagram, but I haven't got around to testing it out yet and don't want to put info out there until I've confirmed it through testing.

Only having one axis is fine for absolutely everything but Model 2 emulator.
I'm sure there is some kind of workaround.
It's crazy because having both pedals on one axis is the default for most PC games.
Absolute worst case scenario is that you map the gas, and make the brake digital.

Whether it needs a 5k pot or not depends on whether it works off of resistance or voltage.
That is something I never tested.  I won't hurt to give the 100k pot a try.
Being that each pot has 3 wires, it probably works off voltage so there is a good chance the 100k pot will work.

Not sure if this is the best deal(just did a quick search_, but this is the type you're looking for:

You'll need an appliance cord from Amazon, Ebay, or your local home improvement store.
I crimped spade connectors on mine, but you could get by with just stripping the wire and wrapping it around the screw terminals.

Hey thanks for the information.  Since I have already ripped apart the Logitech wheel and I have it all wire up, I might just keep the pedals running off of that board so I don't have to deal with that issue.  I'll update you on how it goes...

Thanks again for the help!

[Howard_Casto]

Is model 2 really picky about the pedals and wheel all being on the same stick?

If not then ppjoy and a ahk script should do it.  Read the combined axis, split the value and pass it to two fake axis.  You could leave it running all the time and it wouldn't hurt anything.  The only down side is you've halved the resolution of your pedals (128 instead of 255) but I don't really think that's going to be noticeable.

Alright so I acquired the power supply, and everything is wired up great!  Where can I get that UI I keep seeing for it? I downloaded the driver expecting it to be there but had no luck.

It's part of the driver.
It shows up when you look at the device in Windows control panel.

For Windows 7, it's Control Panel>Devices and Printers
Then right click on the device and select "game controller settings"

For XP it's much easier to find, but I don't have an XP pc booted up at the moment to refresh my memory.
I do remember that there is no right clicking necessary in XP.

Anybody know why force feedback in model2 only turns one direction?  Also, no centering feedback at all.

Strange.  It works fine with other games?

Post your emulator.ini file from your model 2 folder.
If the issue is limited to Model 2, the answer has to be in that ini file.

Yeah the problem is just with model 2 and only since I switched to the immersion board. Here are my ini settings regardless..

I can tell you the problem, although the posted ini will fix it. 

Your Gain for one direction needs to be a negative value.  I would have though this would have been the left gain (left is usually a negative value for joysticks) but Jolly's has it setup the opposite way, so he would probably know the hardware better than me.

[Jollywest]

It could well be the other way round as Howard suggests, my wiring was very trial and error when I rigged it up.
If you have wired yours using Badmouths detailed thread on the inputs/outputs of the immersion board then it probably is the case.

[Hadeys]

Wow, I can't believe that I missed that! Wheel is now responding appropriately, but still no centering feedback on M2 games.  I'll be investigating this further tonight...

[Hadeys]

Okay, so the new settings ini fixed the feedback, and I found my problem with the centering force.  Also, I have concluded that 100k potentiometers do not work with the immersion board.  I'll head out to Radio Shack tomorrow to pick up a 5k pot, which I'm thinking will fix the last of my problems.  Thanks all for the help on getting this all working!

One of these days I'll get around to actually using the Immersion PCBs I bought. Now that I think of it: one of my sets is missing the ribbon cable that connects the two boards. Is there a place where you can buy a replacement or am I stuck making my own?

[Hadeys]

You will most likely be stuck making your own

[Hadeys]

Could anybody tell me how they have their potentiometer wired up to the Immersion board?  I have a 100k pot and a 5k pot, and I've tried each setup, each only makes the wheel respond in one direction.

[Jollywest]

If you look at the blog in my sig, at the immersion post, There is a pic there of how I wired it.
If you orientate the board so the J6 marking on the board is to the right of the J6 header, I have wired the pot wires to pins 2, 4 and 6.
I'm pretty sure 6 is ground, you will have to trial the other 2 wires as to which way round they go though.
My board is probably different from the one you have though, so it's not guaranteed to be right.

[Hadeys]

I have spent the last week or so looking at your blog trying to extrapolate how it is wired up, but it seems no matter how I wire it, the wheel only turns one direction  I currently have the pot wired to the 3.2v, ground, and x axis.  Could anybody offer any insight?

[Jollywest]

That's how it should be wired, have you looked in the Immersion Driver software to see if the axis bar is moving when you turn the wheel?

[BadMouth]

Are you testing in Windows controller settings?
That is where you should start.  Less layers of possible problems.

Did you calibrate in windows controller settings?

I still haven't fully hooked mine up beyond doing some testing to see how everything works.
IIRC, the voltage and ground were specific to each pot.  You could not use the voltage or ground from one with the other pot.
