Is that true of them all ? I am not so sure
I do believe that some controllers have a Switched Mode Power Supply front end that allow a very wide range of voltage inputs. But still, even a SMPS style power input front end, may still need resistor change to work.
From what I have discovered in the last two days trying to get my controller working again, there are at least ( if not more) 3 different design of power front end on the Xie-Chang / Infneon boards
There are two issues here that have be alluded to, but not actually named, and either one may require a resistor network change to fix:
1). LVC issue
2). Power stage issue ( would show itself by low 12v & 5v lines)
As wevhave said, only way to find out is speak to Ed Lyen and see what he has built the board to accept.
Since I have been lead to believe all the newer boards have SMPS power input stages, I suspect an LVC issue.
Oh....... A thought......I was struggling with this issue too, and overlooked the obvious. Do you have a Cycle Analyst? Is it plugged in to the controller?
Do you realise that a CA has an LVC setting too? And if that is set higher than the LVC on controller, then it will not work either. If you have a CA, unplug it. Now does controller work
