Connection to Pixy-LR gimbal (without ENTIRE R3)

This installation procedure is for users who has this setup:

  • Sony ILX-LR1
  • Gremsy Pixy-LR
  • LR1 Expander (for camera control)

In this setup is gimbal connected to MavLink via COM2 at 921 600bps, this data stream is forwarded by the gimbal via COM4 and AUX at 115200 bps directly to LR Expander. LR Expander is connected via bottom AUX port to the Mavlink bus for camera control. Triggering and activating of AF is done via our 6-pin 90deg passthrough connector.

STEP 1
  • Use this cable of LR1 Expander package –>
STEP 2
  • Connect this cable to 6pin connector of the camera and LR Expander module
STEP 3
  • Mount the camera to Pixy-LR gimbal
  • Connect original gimbal cable to our 6 pin pass-through connector
  • Hide our wirings under Pixy-LR clamp for clean result
STEP 4
  • Connect quickrelease AUX and COM4 connector
STEP 5
  • Connect CTRL (COM2) of Gremsy Quickrelease to the Pixhawk controller Telem1 or Telem2
  • Connect power to the gimbal and connect gimbal to the PC via Micro USB cable for gTune app configuration

STEP 6

You have multiple options about control of the Gimbal, SBUS control or MavLink control.

  1. SBUS Control -> please check Gremsy website for installation and add this configuration to enable MavLink connection (without control):

    • SERIAL1_PROTOCOL: “Mavlink2”
    • SERIAL1_BAUD: “921600“
    • MNT1_TYPE: “0”
    • MNT2_TYPE: “0

 

  1. Use new Ardupilot gimbal control fatures (with point gimbal automatically feature)
    • In this case, gimbal will be controlled by the Cube. For this case you have to set:
      • SERIAL1_PROTOCOL: “Mavlink2”
      • SERIAL1_BAUD: “921600“
      • MNT1_DEFLT_MODE: “3”
      • MNT1_TYPE: “6”
      • RC6_OPTION: “214”
      • RC7_OPTION: “212”
      • RC8_OPTION: “213”
      • MNT1_RC_RATE: “90”
  2. For newest Ardupilot firmwares you need to also set:
      • CAM1_TYPE: “5”
    • If you do not have this option in your Ardupilot firmware parameters, Expander will work by default.

(IF YOU USED TELEM2, USE SERIAL2 | MNT2)

STEP 7

  • Connect your gimbal to gTune app in your phone or PC
  • Navigate to SETTINGS->CONTROLS->MAVLINK
  • Configure COM2 baudrate to 921600bps (used for connection to Cube)
  • Configure COM4 baudrate to 115200bps (used for Expander connection)

STEP 8

  • Navigate to SETTINGS->CONTROLS->MAVLINK
  • Configure COM4 baudrate to 115200bps (used for Expander connection via AUX)
  • Make sure you clicked REBOOT after each change

STEP 9

  • Install our MissionPlanner plugin or MavCam to gain control for the Expander (MP plugin installation | MavCam installation)
  • If connection and wiring has been done properly, Expander LED diode now lights blue steady (not blinking)
