Help with Optiwiz - Using TB twist 2 and trackball
<< < (3/3)
UncleMame:
Well after fooling around with it some more, it seems that I have been able to isolate the problem a little better. 

Test 1: Connecting the purple/blue(technically the y axis connector) to the optiwiz on the x axis and y axis work fine. So I would assume that the optiwiz is sending out the correct signals for both x-axis and y-axis.

Test 2: Connecting the yellow/green connector to the optiwiz works neither on the x axis or y axis of the board.  This would lead me to believe there is either a problem with the power connector from the optiwiz to the PCB on the trackball or the PCB on the trackball itself.

Of note, On initial startup in windows, the trackball did work properly on two occasions(maybe it was in its death throws.... :))  It's really odd (similar to uncleT's dilemma).

What do you suggest now Randy ?

This is why I suggest taking these things to email. :)  Looks like we are at a different juncture now, and all of the stuff prior will probably just be confusing to others looking for similar help.

That would be correct.

As I suggested in the second post of this thread, you now need to swap (with the power off) the purple and blue cable at the TB PCB, with the Yellow and Green.  If the Yellow and Green cable works, then the issue lies with the trackball PCB.  These trackballs use the same optical circuit as the HAPP trackballs, and I have seen it mentioned that pulling the power to these PCBs directly is not good for them.  Again, the reason for my "surge" comment earlier.

I suggest you email me ;).  The reason the situation sounds similar is because UncleT's trackball was from HAPP, and uses the same red board circuit. The circuit on these boards is rumored to be very performance oriented, but because it is more complex, it is more sensitive.

UncleMame:
I'll shoot you an email once I get a chance to fool with it some more.

The really baffling thing is this though: If the PCB board is shot(which I think is the likely case) - Why would it intermittently work?(every so often in windows, I would scroll the TB in the x-axis and it would run for a bit and then stop working)  I would figure if a board is shot, it is shot, no in-between.  But then again, UncleT had the same thing happen.  I'm certainly no expert on PCB design, so who knows.....

I didn't realize the TB3 is essentially running as a Happ(PCB wise).  It's just a shame to know the Happ PCBs are so fragile (I've been far more gentle with my CP PCBs than with any PCBs I've mounted to mainboards/slots) - kind of funny how a cabinet gets extra special care  :).  

Just as a side note, the USB connectors were disconnected at the computer not directly at the PCB board(I don't know if this makes much difference in regards to your prior reference about the disconnect).
