Banner Web trouble

I’m a high school student who’s been accepted to Rose-Hulman, and I’ve looked through all the emails and physical letters I’ve gotten from them… I’ve been able to find a Banner ID, but no PIN. Am I missing something obvious or do I need to contact them to figure out what the problem is? Is Banner not going to be open to me until I receive financial aid information later this month? I have been notified of scholarships and assumed that I would be able to log onto Banner to view those.

Update - at the financial aid video chat yesterday they said we would receive the PIN with our financial aid award letters.
