Thanks for your kind patience it taking these readings. I note these were done with Hor Ext in. I dare not ask you for any more! I have a theory, however, if you can see your way to taking the trouble, just for completeness, it would help to have pin 3 and 4 with AT off, Hor Ext OUT, no sig, intensity max please? You don't need to bother with any others.

BTW,, there was a large jump in the focus voltage (-615 vs -716) which is interesting since I would have thought that this should have stayed the same more-or-less unless the focus was changed dramatically.
