Fusion 7 Display timeout ConnectCore6 SBC Pro

I am using GStreamer with the ConnectCore6 SBC Pro and I was able to get my USB web cam streaming to the 7" Fusion display. I used the DEY-2.4r2 release as the OS and copied the Display setup from here: http://cms.digi.com/resources/documentation/digidocs/embedded/dey/2.4/cc6plus/yocto_t_enable-fusion-display

The gstreamer command works fine but after 2 Minutes the Fusion display turns off. I can only start it again by re-running the gstreamer command.

How do I set the display sleep time on the ConnectCore?
