Subject: SCART specification question
I've been asked to look at a gadget which is intended for connection to
the
SCART port on a TV or VCR. The gadget in question is powered via a
plug-top
transformer, which we can specify to be SELV output.
My question relates to the specification of the SCART port which is, I
guess, a standard configuration (although a key-word search on SCART in
the
BS catalogue throws up no references, I notice...)
Is it, or is it not, safe to assume that connections made to the SCART
interface are SELV? In other words, even if we ensure that all parts of
our
product powered at SELV, do we have to treat those parts connected to
the
SCART interface as potentially live, or can we assume that they too will
be
SELV?
Any ideas (including a reference to the basic SCART specification) would
be
helpful.
Regards
Nick.
