How to stop iPad from launching Nikon Transfer?

When I connect my iPad to my MacBookPro ( via the USB cable), the Nikon Transfer software launches. This is software provided by Nikon to transfer pictures from my Nikon camera to the Mac. Because connecting the camera to the Mac via USB also launches Nikon Transfer (have it set that way for 2 years now), I assume that the Mac thinks my iPad is the camera. Any idea how to keep Nikon Transfer from launching when the iPad is connected? I am able to do everything in iTunes related to the iPad, so its more an annoyance than actually causing a problem. But still would like to address it if possible.

Thanks and regards,
