Hello,
Has anyone passed RS485 throught the tether for sonar/altimeter?
Any interference with BR2 ethernet communications?
I have 300meters.
Alternatively, can I pass it through the ROV’s raspbery pi?
Cheers,

Hi @etienne,
Yes, you can use the RS485 without problems because of the differential pair.
Yes, it’s possible to use a python script or netcat to create a bridge between your sensor and the top side computer.
There is a utility built into the Pi that allows you to select a serial interface and link it to a network interface. Look for the ‘Routing’ page in the web ui. This tool is not very efficient at the moment and isn’t great for high-bandwidth stuff. You can use netcat like this:
netcat -ul 0.0.0.0 <port> > /dev/ttyUSB0 < /dev/ttyUSB0
or
netcat -u <ip> <port> > /dev/ttyUSB0 < /dev/ttyUSB0
Yes, I also can confirm it works. Tested with an Imagenex 852 sonar and 200m tether.
Thanks everyone. I’ll try it through the tether.
