Thanks for the responses, problem solved. slobob, agree I learned the hard way earlier on to do a download before testing. Turns out that the Fujitsu (and the NAD M15 preamp) need pins 2 & 3 swapped in the URC serial cables to work (I'm using female cables, the NAD needs a gender changer so it might work OK with a male cable, the Fujitsu does not). A little wire surgery later and everything is working OK.

skynyrdfan, I'll post more when I have this all working properly, but so far the MSC looks like a great piece of gear and apart from this issue easy to set up and program. I'm especially interested in adding sensors and macros so that for example the NAD preamp will be automatically turned on and set to the right input and mode if the Sonos box for the living room starts playing... unless that is the M15 is already on and has a video source selected.
