Optional: power the MS-700 with the drone
The mounts are provided together with the DJI E-Port V2 kit. This kit is fastened in a custom mount that attached to the carbon rods. The connection to the drone is made by any of the four E-ports located at the bottom-front side of the M400. The MS-700 sensor can be powered with any of the XT30 ports, however it is advised to use the middle port that provides 12V.
How to use the mount
Rotate the thumb screws counter clockwise, then press the sensor assembly onto the carbon fiber cylinders, use the cylinders as leverage if necessary, not the drone’s body. Once the sensor assembly is clicked around the cylinders you must rotate the thumb screws clockwise. It is advised to always hold the sensor until all four thumbscrews are secured.
To dismount the sensor assembly simply reverse this process.
