Mount the Entire unit at the other side of the bottom of gimbal.
SD Card should be aimed outside of the gimbal for easy handling in the fields.
Use double self-adhesive tape or self-adhesive zipper is suggested.
Connect Power Adaptor to the Entire (PWR connector) via Power cable
Connect Gremsy AUX port to the UNI A port of the Entire by AUX Cable
AUX Cable has two separate twisted groups of cables. One has red wire included and is connected to UNI-A of the Entire. Second group of cables with single wire connectors at the end are unused AUX pins.
Unused pins of AUX port (black wires) can be used for any additional connection same way as original AUX cable included to the gimbal. In our case we remove these pins from AUX connector because all data and control signals are transferred via UNI-A connection.
Clean up wires under the gimbal by Zip Tie.
Mount the Camera and connect Multiport cable to the USBMULTI connector of the Entire
Entire is able to control the camera instead of USB also via IR commands. IR commands are the only way to access and navigate in the MENU, also IR commands allows user to use shortcuts (user mappable in the camera MENU) at LEFT/RIGHT/DOWN arrows.
Use EXT Cable with IR LED and red sync wire and connect it to the EXT port of the Entire
Mount IR LED to the IR sensor of your camera (remember to enable RemoteCtrl function in the Camera menu). Optionally you can use our IR LED mount (not included).
Insert HotShoe connector into HotShoe connector of the Camera
Connect the red wire from EXT cable to the HotShoe connector
Mount top bracket of the gimbal to the rest of HotShoe of the Camera
function in the Camera menu). Optionally you can use our IR LED mount (not included).
Entire uses multiple simultaneous connections to access all necessary data for geotagging. At the top of the gimbal we need to provide you back the rest of unused AUX port pins and also interconnect the COM port. For this we use Interconnection board which is mounted at the top of Circular Damping Mount, however can be attached at any other mount you would like to use.
Insert two screws to Interconnection board and attach distance tubes as per photo
Mount the Interconnection board and pay attention to orientation to AUX and COM ports below the mount.
Interconnect Gremsy AUX at Quick Release to -> GIMBAL AUX port at the Interconnection board
Interconnect Gremsy COM at Quick Release to -> GIMBAL COM port at the Interconnection board
Port named EXTERN-AUX at the Interconnection board can be used for any other connection used at your drone by original Gremsy AUX cable
Extension BOX is very important in our design. This little unit is used to transfer multiple data signals via only two wires to the Entire. Extension BOX has four UNI ports which are multiplexed to the DATA connection and transferred to the Entire.
Extension BOX should be mounted at the drone body.
There are two connections of the Extension BOX to the Interconnection board. One is DATA transfer of all UNI ports to the Entire, second is used to read the data stream from the Gremsy COM port for reading of actual gimbal angles.
Connection 1 – Use UNI cable and connect DATA port of the Extension BOX to the DATA port of the Interconnection board
Connection 2 Use UNI cable and connect PORTx DJI of Interconnection board to the UNI-3 of the Entire
Remove the top plastic cover of DJI M600 Center Frame
*Connect SBUS cable to the F3 port of your A3/N3
Connect API cable to the API connector of your A3/N3 SEE THE PICTURES ➜
Thread the cable (or cables) down through the body of the drone
SBUS and API Cables threaded through the center frame now must be connected into the Extension BOX.
Use UNI-1 for SBUS (PWM) and port UNI-3 for DJI API cable.
(You are free to use any port, UNI-1 & UNI-3 are used here to match next steps of this manual)

Following settings is valid for Gremsy Firmware v574
Power on the Gimbal and connect the gTune application to the gimbal via BlueTooth or WiFi
Click to SETTINGS -> CONTROLS -> Confirm YES
For DJI users, or for PixHawk users without gimbal-PixHawk connection set MSG RATE of all to 0 only ORINETATION set to 25 (25Hz, can be set higher for higher accuracy)
Once configuration is done, you can switch back for SBUS or other control method. If you would like to use MavLink control (use PixHawk-Gimbal connection), please follow proper Gremsy manual for MavLink configuration.
Power ON the Drone and the Gimbal
Check if the Entire is powered ON via Power Adaptor
Check if the Extension BOX is ready (blinking blue or green)
Once Entire becomes ready (STATUS Blue) use your phone or any other WiFi equipped device and access Entire’s WiFi hotspot.
Entire FW update can also contain firmware update for the Extension BOX. If does, the Entire will update FW in the Extension BOX automatically. Process takes only few seconds, however during the update Extension BOX is available and STATUS LED is OFF. Entire’s STATUS LED is Purple during the update. Do not disconnect Extension BOX during update!
Bar should become highlighted “online” after few seconds (or orange for FW update)
Extension BOX should start blinking GREEN (Active)
At the overview page you should now get four new UNI ports available (1/2/3/4)
Click to “UNI port 3” bar and in new window select DJI. Port should become “online” in few seconds.

Overall wiring scheme
Options of Gremsy connection
Gimbal control This option is used to control of the gimbal Pitch and Yaw via AIR Commander Link.
Force SBUS mode This option forces gimbal to use SBUS mode. At latest firmwares of the Gremsy (765 and later), gimbal locks in MavLink mode, once Entire is connected. Entire can force gimbal to use SBUS mode via MavLink (with this option enabled). You have to set gimbal to SBUS control mode also via gTune app. If you would like to use MavLink control of the gimbal, leave this option disabled and enable “MavLink forwarding“.
MavLink forwarding With this option enabled will the Entire forward all input MavLink data (received from PixHawk) to the Gremsy gimbal and also all data received from the gimbal are forwarded to the PixHawk. This option is used when gimbal is controlled via MavLink ot you need to get direct communication with gimbal for example from ground station.
Gimbal tuning (Herelink) This option enables remote configuration of stabilization parameters. Remote settings of those values are available only from MavCam (HereLink app).
