chapdis,
The Cas Interface that I have is "Cas Interface 2" it does not indicate anything about +Plus version.
I am OK with selling you the Cas Interface 2 and the Diablo Cam v2.3, however, I think that you need to make sure that they are OK for your needs before buying them. I do not wish to sell you something that you later find is no good for what you wish to do so please make sure they are OK before we discuss a price.
