I am trying to connect a Benewake TF03-180 lidar unit to a pixhawk2 cube for distance ranging. I am having trouble getting the lidar to even turn on. I am using 5v directly from the drone. The lidar unit has power, ground, rx uart, tx uart, rx 485, tx 485 wiring. this is where I get lost. I had power and the rx,tx 485 wiring all connected but nothing coming from the lidar sensor.
Any help is greatly appreciated
