Need help with land and sea dyno


I bought a land and sea Dyno from a guy a year ago and I'm just now getting the unit up and going. My problem is the Redbox that has the four buttons on it isn't communicating with my computer. I'm getting Port 1, port five, and port 3 errors for some reason. Can anyone help me?
Don what data cable are you using? Those boxes are very finicky as to which one you use. Feel free to call me, Matt 814-771-8987
