BIND T16 pro with internsl module

Im trying to bind my T16 pro to couple of dsmx/dsm2 whoops i read you turn off both internal and external but then where do you hit bind on remote then i read both have to be on? Crappy part is ive set them up before but cant remember ty for any replies

From what I’ve read they both need to be turned on.

You only need to have the internal modual on. Set it to dsmx and bind as you normally would.
I have a dsmx in my alien and had no issues binding to my new t16 pro.
