-make sure your PWM's are gving out more than 5 VDC (we had that problem, then we just ran the camera off of a seperate 12V battery with limited current)
- the jumper near the top right of the camera across form the serial cable needs to be on
-be sure you get a red and green LED lights
-if you haven't already configure the serial port to the proper data bit rate.
-Just power the PWM at the bottom and use the serial to your computer.

that's all i can think of now
