You will need a higher isolated supply. I use a little 12v to 12V DC converter to give the isolated supply, and just limit the range of the input. Sounds as if you are nearly there though. -- Lester Caine - G8HFL ----------------------------- Contact - http://home.lsces.co.uk/lsces/wiki/?page=contact L.S.Caine Electronic Services - http://home.lsces.co.uk MEDW - http://home.lsces.co.uk/ModelEngineersDigitalWorkshop/ Firebird - http://www.firebirdsql.org/index.php ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
