I think that the input jack on your G90 is
Sony's "control-S" and they are not compatible.
But there might be a fix for you, I think that
Xantech has a box that you could connect between
the IRF6 and the projector. Send an email to
the Xantech support: [email protected] and they will
know.
An other option is connect the IRF6 and G90 with a
serial cable instead.
