[Volt_Ampere]

The manual that comes with it shows you how to hook up but it's just USB. You can download the software and user manual from Alltrax website. It is very easy to use. IT shows every input to the ALltrax and what state it's in so you can test all switches and throttle. Most important, you can set up everything for your motor and throttle type. You can also log all switches, voltages, currents while driving and go back and look at them later to diagnose problems or just see how it's operating. A very useful tool!
