TeraRanger Evo 60m


I have installed 8 TeraRanger Evo 60m sensor on my Hexa copter with one on each side and two installed on the bottom. When I set
PRX_TYPE = 3 to enable the TeraRanger EVO sensor Mission Planner go in to Failsafe mode.

Any idea on how to resolve this?


Configuration through the Ground Station

Setup in Mission Planner

To use the TeraRanger EVO sensor as rangefinder, connect with Mission Planner and open the CONFIG/Full Parameter List menu and set:

  • RNGFNDx_MAX_CM: This parameter sets the maximum distance that the rangefinder is used by the autopilot.
  • RNGFNDx_MIN_CM: This parameter set the minimum distance that the rangefinder is used by the autopilot.
  • RNGFNDx_ADDR: 48 (for TeraRanger One) or 49 (for EVO series), 0 will disable the rangefinder setup.
  • RNGFNDx_TYPE: 14
  • RNGFNDx_ORIENT: 25 (for downward facing). If used for Object Avoidance or ceiling distancing, instead of altitude ranging, mount and chose the appropriate orientatioin.

Values for the rangefinders are shown below:
