Fathom X tehter interface link not working

Blue Robotics Products Tether Interfaces

Dear friends,

I have lost communication from the Qground control to the BlueRoV2. The ground Fathom X board shows the power led on all the time but the link led blinks at power on but then it is off all the time.

On the ROV fathom X board, the link led is on for about 14 seconds after power on, but then it turns off. I guess it is working, but when it detects no signal from the ground Fathom X it turns off.

Any ideas of what tests to run to detect what the source of the failure can be?

Hi @manci -
Welcome to the forums!
Without the link light remaining on, you won’t get a connection via the Fathom-X.
The best thing to do is verify tether continuity between the two units, and potentially switch to using a different tether pair (3 are unused in a standard 4 twisted pair tether.)

To switch, you’d have to chage the connection both in the ROV and in the FXTI topside box.

Thank you for your comments. After some retrials, the link led and comms work only from time to time. I think it is the USB connector wich does not do a very robust connection. I am tinking of removing the USB connector from the Fathom X Tether interface Board and solderind the USB wires directly to avoid contat issues. USB connectors are not a very robust solution

Best regards
