Can I connect a Pro Ais via USB to Lightening cable to my iPad 5th gen.
Connect Pro Ais through USB to lightning connecter
iPad, iPadOS 16
Question marked as
What is a "Pro Ais" does it have an associated app you can run on an iPad?
Does its manufacturer state is compatible with an iPad?
Are you perhaps referring to a Radio Transponder receiver for maritime use? ie on a boat?
The USB to lightning port adapter can be used to connect different things like external drives, keyboards and mice for instance.
You can physically connect the device to the iPad, but whether it will then be usable by an app, on it is a different question entirely. The iPad on its own won't acknowledge it or tell you it's connected at all, and won't be able to access its data directly. It will depend on an App that can read data from it.
If you mean something else, then please clarify.
Hard to provide any help with so little detail.
