Danny, thanks. The iTemp is connected to the SL1 and appears to work correctly. I will keep my eye out for a HUB and cable that is reasonably priced, but so far - haven't needed it as it's pretty easy to just unplug the iTemp from the SL1 and connect the USB to that bus port. At some point, I may look to update the SW on the RKL. I'm at 2.04 and not sure what benefit I get going to 2.06. So far so good with getting the existing DA stuff programmed and working as I expect.
