I recently purchased a EZ4 board and I was anxious to use it. I went through two cables (mini din to molex) both of them traced correctly but yet I got nothing when I went into EzBuilder.
The camera functioned (although it appears to only take up half the image window), I could connect to the web server no problem, but not the Roomba (although it acted like it wanted to connect).
In your pin out you have two pins being used one is ground and one is sending 5 volts (pin 3) to the create. Which confuses me because the directions make note to measure the voltage coming from the cable however I believe pin 3 SENDS to the Roomba not receives, am I misunderstanding?
My last attempt I took a PS2 cable put a meter lead on the pins you mentioned and then on the bare wire, until I had a complete connection. I attached those two to a molex connector with servo wire double checked the connections and still nada.
Help? *stress* *tired*
