3irobotix Delta 2A LiDAR

Hey.

A while ago I got this 360 degree Lidar.

It works perfectly fine connected to the computer via included USB board.
What I failed to realize before, is that the unit itself only has 5 pins:

M+ Motor +
M- Motor-
VCC
GND
TX

No RX. I can’t seem to find out what kind of communication protocol that could be. Is it possible to connect it to the Pixhawk1(PX4) flight controller or is it time for me to abandon hopes?

Thank you.
