The RT is a bit more complicated. It's newer version, the RT Pro(RTP) has major differences from its predecessor. Still, both perform the same.
In this section I will talk about these markers which constitute the entire AGD mechanical marker line.(excluding the sydarm - very few people have them, if you do chances are you dont need info on it.) I'm not going to get into the operation of the entire valve. However I will do my best to cover everything I can think of in the debugging section. If you have any other questions, contact me.
