RE: Keene IR - Compatible with Xantech ?

["Keith Doxey" <ukha@xxxxxxxxxxx>]

Im pretty sure that the Keene IR receivers operate on 5v because I was
working on system last year and I used a couple of my KAT5 IR reievers with
it. They are 5v.

It may still result in the magic smoke escaping even if the polarity is
correct.
