I have a robo claw 2x 60 motor controller. I have ezb4 connected via DO and D1. I am connected to the EZB4 with my computer as I can send sound files to it and it plays out the EZB4. I have assigned ports DO to left motor and D1 to right motor. I cannot make the motors do anything. I have previously used this controller with a RC receiver and it worked. Is the EZB 4 not able to replicate those commands? Do I have to speak with it serially? A script? When I read the script control instruction it says something about needing a Movement Panel associated with it? Thanks ahead of time.
