Re: DLink / D-Link resets going over bumps! Thoughts?

Tis a puzzlement.
I would have guessed that the failure mode on this device would a zero volts or 12 volts. Since it is not zero, 7.3 seemed to be low. I have not found any real data on this device on the manufacturer's website so there is no way to point at a particular type of convertor. So I am going to say it is defective but this is what I think might be the failure. If it is a switching type of regulator, the frequency might be so far from design that the output is not able to generate any current. Have you looked at the output with a scope? I am guessing there is a fair amount of AC voltage on the output and your meter is measuring that and interpreting it as 7.3 volts DC.
Of the teams that have reported that they hooked up their DAP to 12 volts and killed it, some may have reversed the voltage prior to the connection. Maybe you are just super lucky. With that kind of luck, I hope we don't play against you this year.
