I could never get it to work, so I ended up building a hardware interface based on a ripped apart IQ remote, and a small interface board produced by another member here.
It was a bit of work, and you do need to understand a bit about electronics, but it works 100% and now I don't have to deal with that useless IQ user interface.
Have a look at this thread for some info.
