I’ve just did my first dive test after installing a ping 360 and a ping altimeter. These are installed on a BRov2 Heavy with aluminum housings. I ran out of penetrations in the main housing so I have a separate 3" housing with power, the newton gripper, and both sonar penetrations, then I used a single 15 conductor cable to connect all three instruments back the the main housing via a single penetration. While sitting on the bench, all appears to be functioning correctly. However, once in the water, both sonar systems crash as soon as I start to dive. Both sonar systems show a bunch of static ‘noise’ and the ping programs freeze within seconds. I have to reboot the brov2 and restart the software to get it to work again.
So, I believe I’ve isolated it to when the #8 thruster is spinning and I’m fairly sure that the wiring for the sonars runs right past that ESC - though I’m not positive.
-The wiring is foil jacketed and twisted but would it be safe to assume I am getting EM interference in the sonar signal wiring from the thruster ESC? Or elsewhere?
-If so, why would it only occur in the water and not in air when I run the thrusters?
-What would be the best way to shield that wiring?
-Is there any way to restart the ping360 or altimeter without rebooting the onboard computer?
