Apon wirring my webrick to my Soundlab dimmers through the anologue outputs i found that the 240v lighting conected to the dimmer would only go to what looked like 50% the brick was indercating dimmers / anologue outs at 100% (confused) after re-assesing wirring 240v and low voltage it was found that if you use the G of the 1 wire data bus on the webbrick at 100% on the A/ output you were only getting 5v where should be 10v. Error or just a work arround anyway just thought i would post it. Andy if you have any explanations they will be welcome.

 I do !!

 The outputs are 0-10V, but connecting the 5V you were getting a -5 to +5 signal.  The dimmer will only operate on the + side, therefore the 50% as reported.

This also caused the problem you reported on the WebBrick interface - which I'll note separately because its useful to everyone!

 So is the G in the Temp section not a common G like the others on the brick?

Alex 

All 'G's on the WebBrick are connected to the same plane.  The only exception is the protective ground which is simply a barrier between the ELV (extra low voltage) and the LV (main end).

 I made the guess that you'd had accidentally connected one to the left because I've seen identical symptons before!
