[PAL:Error] Camera is not connected!

[PAL:Error] Camera is not connected!

Hi!

I'm trying to get SLAM working on the PAL-mini using the provided nvidia board. I'm able to use the installed Explorer software to view individual images from the PAL. However when I try to use the navigation publisher I get the following error. Any insight? If I run ros_demo.sh I also get a UI for SLAM, but no images.

Thanks!
