Mitsubishi city Multi - Identify fan coil BC ports

Hi

Can anyone tell me how to identify what ports indoor units are using on the BC box. Turns out the "as fitted" drawing are basically mince and do not identify the ports correctly.

We have around 40 - 10 port BC boxes with almost 400 indoor units - so don't really want to open up all 400 to get address's.

We use TG2000 software - but cant see how to get that information from the software?

If I had the monitoring software - I believe I could hook my laptop up to a G50 controler and hey presto - but unfortunately - it seems almost impossible to get the software unless you are a gold partner :(.

Any ideas much appreciated
