Just to help us help you here are some basic questions.
How are you determining that they are outputting reverse/forward all the time?
How are your motors wired?
How did you determine ports 5-10 are working properly?
What speed controllers are you using and are they wired properly?
My suggestion is to first focus in on your drive base. Get it running, and drive it into the ground and see what breaks. Then fix it. Rinse wash and repeat. - Andy A. [more]
