That version shouldn’t be a problem. You don’t need to order a 188E with software but if you buy a new one, you’re going to get a KY14 and it needs at least, I think, V4R5D. So if you don’t have it make sure they give you the latest, V4R5P is what I have. What part # 188E old and new do you have? I can’t think of anything that would cause your door comm problem but a bad 188E if the old one works and you’re using the same Job file in both.
