The instructions on
this page worked for us. I'd recommend you don't assume anything about the current IP addresses of camera or computer. Just reset the camera to factory defaults and change your computer's IP address (temporarily) per the instructions.
Note in the first step of the instructions that you MAY require a crossover cable when connecting the computer directly to the camera.
The camera setup utility that FIRST provides in the
Utilities update has instructions for resetting the camera to factory defaults, but basically:
1) Unplug the camera's power cable
2) Press and hold the black reset button on the back
3) While holding the button, plug the power cable in.
4) Continue to hold the button until the LED ring on the front comes on (initially orange, I think).
5) Once the LED ring comes on, you can release the button. Then, wait a bit for it to turn green.
When you're done setting up the camera, remember to change the computer's IP address back to 10.xx.yy.5 (where xxyy is your team number) - assuming this is the computer that you'll be using to develop code and communicate with the robot.
