Hi Stuart,
I have managed to get the RS800 and the mac to talk to each other reliably via the Belkin USB IR reader.
Thanks for your support and advice in helping me sort this out.
I have now got to the stage where the sessions get transferred across and I basically have a diary of training sessions with cals consumed and peak / lower HR.
The continuous HR recording do not seem to be transferred reliably.
On only 2 occasions did some HR data come across. I can't see and obvious change that I have made. Presumably there is a selection somewhere that I am not ticking.
Any help much appreciated.
Tito
