Can't get WinXP to see the Trackball

Well, that isn't what I'd hoped to hear! I was thinking the only thing I had not tried was re-enabling all of the Services in XP, and that was the common denominator of two Opti-PAC's not being identified on two separate machines.

I have the USB version and also tried it in serial mode before finally giving up.



RayB:

I have a serial optipac and it required a couple reboots, plus also rolling the ball around at the same time and eventually it found it.

Okay, it seems I have a power problem. This may merit a new thread but I'll try this one, first.

1. I had been reading my multi-meter wrong, looking at the wrong row of numbers. What I though had been 5v was slightly more than 1v. Not enough to power the TB, so no wonder Windows wasn't finding it.

2. When I read the supplied harness coming off the I-pac pins (for the optipac) it reads nearly 8v (more than 7, anyway). But as soon as I hook it up to the optipac, or directly to one of my P360s, it again drops to between 1-2v.

3. Here's the really weird part: when I put my multimeter black sensor on an Ipac GRND terminal, and the red one on ANY OTHER screw terminal, I'm seeing almost 8v. I'm thinking this is a problem.

I'm at a loss here. Any advice?

TOK:

Using the USB version w/digital multimeter, my numbers at the encoder were correct based on the Ultimarc page, 5v at the Opti-PAC power terminal and varying from .5 to ~ 5v depending on if the encoder sensor was blocked or not.
Seems we have different issues here. My problem was that everything appeared to be normal, except neither of my PC's would correctly recognize the Opti-PAC.   ???



JCKnife:

Okay, problem solved here. I tapped into power from the PC psu and everything works fine. I guess I have a faulty IPAC but with a working solution, I'll leave well enough alone.
