Any tweaks I can do to get the diagnositcs to work with the EDU?
We use the camera with the Edu... We got the same error initially. We found that the baud rate was set wrong. If you are using Serial Port #2 (the TTL header is serial port #2), you need to change Kevin's serial driver to use a baud rate that matches your camera (the default is 115200).

Another thing to check - make sure your RS232<>TTL converter board is fully connected. The Edu has only 3 pins on the TTL header. The missing fourth one (as compared to full size RC) is the power pin (+5V). We took the end of a spare pwm cable and connected just one pin on the +5V pin of Digital In/Out #1, then ran that into the TTL<>RS232 board.
