Adding Lightware LIDAR

I am trying to add a Lightware LIDAR unit. See LightWare SF10 and SF11 Lidar — Copter documentation

I have set these parameters
SERIAL4_PROTOCOL = 9 (Lidar)
SERIAL4_BAUD = 115 (115200 baud)
RNGFND1_TYPE = 8 (LightWareSerial)

I can’t find the following parameters in current stable version of Mission Planner V4.3.1 are these only available in V4.4.0 dev?
RNGFND1_SCALING = 1
RNGFND1_MIN_CM = 5
RNGFND1_MAX_CM

Please reboot your board and refresh the parameters. The missing parameters will appear

Not sure what reboot means and if you are referring to Pixhawk 5+ firmware or Mission Planner

Do you mean reinstall ArduPilot on Pixhawk controller or Mission Planner on pc?
Sorry I am a beginner.

By reboot I mean power cycle the flight controller.

No firmware nor software change.

Google is your friend

Does the LIDAR unit need to be connected for these parameters to appear?

Disconnect and then reconnect the batteries. Don’t forget to unplug the USB cable before you do this.

No, it does not need to be connected.

What flight controller are you using? does it have 2MB memory?

Pixhawk 5+ with 2mb

I am seeing additional parameters now thanks but no data for lidar or Pixflow in status tab after adding additional parameters. Will work on it tomorrow.
