Hey all, I just got an intravolometer for Christmas. It is a cannon TC-80N3, and looks to be pretty freakin nice to say the least. However, I noticed to control input on my T3i looks to be like a normal audio headset jack, and then plug in for the controller is a bigger, almost square looking jack. I wouldn't imagine these two devices to be un-compatable, considering they're made by the same company.. I really don't want to take this back, so any help would be much appreciated
