OK, here are the results.

Using 4- Sanyo NiCad 1.2V 250mAh batteries(the ones Parallax use to sell) I was reading 5.09V at the leads. The breadboard is standalone with no connections to any other board. I am unable to use debug with the Key Ring in place.

If I remove the Key Ring and use only the SX Key, I CAN use debug while powered with batteries.

I also tried the Key Ring using 2- Duracell 1.5V batteries. The power at the leads measured 3.18V. The debug didn't work either.

I tried connecting the board power to the Key Ring, I tried removing the power, removing the ground, every combination I could think of.

Shorter leads do not correct the problem either.

The ball is back in your court....ideas?
