Thanks for the feedback, I've tried several times to no avail. I'll disconnect my AM21, perhaps that is not helping. Per your advice, I'll try the reset button while both devices are powered up. If I don't get this fixed soon, I'll send the Apricorn device back (and shame on Apricorn for advertising D* capability). Now of course I knew there likely going to be compatibility issues with the dumb D* box (I have an HR21), but someone browsing Apricorn's site may not know, perhaps they should have some disclaimer on their site.
