Have you gotten this message in the AVerPlus software when you try to pull up the document camera image into your software so that you can annotate over it? I sure have, and one of our pilot site teachers has as well.
Here's how to solve it:
There is a switch on the side of your document camera that has a little arrow underneath it. If your document camera isn't showing up in the software, move that switch in the other direction.
There is another switch on the other side of the camera. It says "TV" on one side and "RGB" on the side. It should be switched to RGB.
Let us know if this doesn't work for you!
