Hello, I am slightly confused about which protocol is needed to run dynamixel servos. I purchased a few ax12 a servos for lower strength applications, but I'm also interested in an mx 64 t or 64 r which appears to be either ttl or rs 485 protocols. Which protocol does port d5 on the ezb 4 use. I read some posts from old bit builder , he was using ax 12a as well. The picture on the plugin page has a rx 64 servo shown which I thought used a completely separate protocol. Very confusing. I would like to be able to daisy chain elbow rotation, elbow flex, and wrist rotation servos together in a ax12a, mx64xx, ax12a layout. Thanks for the help.
