Ping sonar lose contact with the Rov

Have a problem. When I connect to Ping sonar USB AS on the video. The camera disappers and loses contact with the Rov. Sorry for the bad video.

Hello,

This seems like a power issue, are you using the retired 5V 3A Ubec? You may need the new 6A revision.

Hello,
I have used 5V 6A Power Supply but the ROV looses video after 30 minutes. Any tips? What can be the issue? Thanks
