I'm assuming that it would be allowed as it is only a Digital signal but before we use any I'd like to make sure. I can't seem to find anything in the manual prohibiting them.

As long as you use IR you should be fine, there are laser beam break sensors that serve the same purpose, these would have been illegal in previous years based on the ban on lasers. I am not on a team this year and have not verified this rule still exists.
