BC 9500 - Tape 2 trigger?

I have a BC 9500 with an Airport Express feeding TP2.  This works great, but…

Is there a way to trigger the BC 9500 to wake when a signal is sent through the AEx? 

I’d like to automate some features.  For example, I can today tell Siri to “play XYZ in the Library” and the signal is sent, but I have to manually select the TP2 function on my trusty Beo4 (or tap on the unit's keyboard) to wake up the BC.  Simply sending the signal via the AEx doesn’t trigger the BC9500.

Ideas?

I think that might do what you want

Thank you, madskp. It does look like it might do what I want, but requires more effort than I can muster. . Arduino programming is a mountain too high & a bridge too far for a mere mortal like me. Thanks, however.
