I'm struggling getting my ARRIS CM2000 Interface Software to read my gimbal. On my computer, I only have COM4 to choose when I connect to one USB and COM3 in another USB, I click on either and then click on "Read" and nothing happens. All I see is a bunch of zeros. Any ideas? I'd like to be able to setup the gimbal so I can manually control the pitch. I can move the gimbal but I need to be able to make adjustments to the gimbal so I can control the pitch angle. Right now all I can do is make the pitch go from pointing up into the props and straight down onto the ground.
