Ping sonar with ArduRover

Hello everyone!
I am trying to set up the ping sonar with ArduRover (flashed on an OrangeCube+). I was able to use a USB2rs232 adapter to verify that the sonar works. Then I followed this tutorial to configure ardurover and used the appropriate connector to connect the sonar to the serial 2/telem 2 port. However, I am not able to get any data from the sonar in the mission planner. Also, once connected, mission planner says, “No data from range finder.” I would appreciate any help with this :smile:
