This section describes how to set up the CONNEX Air Unit (transmitter) and connect it to the drone.

We highly recommend that you use the provided AMIMON accessories and cables. If alternate products are used, make sure that they are of the highest quality.

To set up the CONNEX Air Unit:

  1. Assemble the Air Unit/drone mounting plate:

    If attaching the Air Unit to a flat surface on the drone, perform the following:

    • Place the Air Unit in the center of the provided mounting plate, on the side with the mounting plate bumps protruding.
    • Use screws or plastic ties to secure the Air Unit to the mounting plate. You can thread the plastic ties through any of the holes on the mounting plate.

    Attaching the Air Unit to the Mounting Plate

    If attaching the Air Unit to a bar on the drone, perform the following before attaching the Air Unit to the mounting plate:

    • A clear plastic holder is provided to help attach the mounting plate to a bar or to the landing gear of the drone. The square plastic insert can be placed in the opening in the center of the mounting plate either horizontally or vertically, according to how you want to position the mounting plate relative to the bar to which you are attaching it.
    • Insert the plastic holder into the opening in the square center of the mounting plate, as shown below:

  2. Attach the mounting plate (with the Air Unit attached to it as described above) to the drone using screws or plastic ties. Typically, it can be placed on the bottom of the drone. Make sure that the Air Unit’s ventilation openings are not obstructed.
  3. Attach the Air Unit cable antenna mounting accessories to the drone. Make sure the mounting accessories are placed close enough to the Air Unit for the cable antennas to reach the Air Unit's antenna ports.

    IMPORTANT! For optimal performance, carefully read and then implement the guidelines provided in Placement Guidelines - Air Unit Cable Antennas. These guidelines describe the best mounting options for the Air Unit cable antenna options.

  4. Connect the two Air Unit flat cable antennas to the two Air Unit cable antenna ports, as shown below:

  5. Connect the provided Micro to mini HDMI cable from the HDMI IN port on the Air Unit to the camera.

    The right side of this cable goes into the Air Unit HDMI IN port.

    The left side of this cable goes into the drone's camera.

    Close the HDMI Connector Screw (to the right of the HDMI IN port) to stabilize the connected HDMI cable to the Air Unit.

  6. Connect the provided Air Unit Power cable to the power port on the Air Unit.

    The right side of this cable (as shown below) goes into the Air Unit power port labeled 8-26-VDC.

    The left side of this cable goes to the battery.

  7. Connect the other end of the provided Air Unit power cable to the power source (battery). Use an 8-26-VDC voltage battery.

    Verify that the Air Unit Power LED  lights up. (See the Air Unit Power LED table below.)

  8. The Air Unit automatically connects with the powered on Ground Units that are paired with this Air Unit.

    A connection is established between the Air and Ground Units regardless of whether video is transmitted on the wireless link, as follows:

    • If video is transmitting, the Ground Units display the video.
    • If video is not transmitting, the Ground Units display the message: No video detected. Please check video source.

    The Air Unit’s video and transmission status is indicated by its LEDs, as described below.

  9. [Optional] To display information received from the drone's flight controller overlaid on the video on the Ground Unit monitor, refer to Connecting the Telemetry Port.

 Air Unit - Power LED

On (White)

The Air Unit is powered on.


No power is being supplied to the Air Unit.

Blinks Quickly

Indicates a system error.

 Air Unit – Video LED


The video signal from the camera is locked, meaning that it is being correctly received by the Air Unit from the camera.

Blinks Slowly

The video from the camera is not locked, meaning that the Air Unit is not receiving the video from the camera.

Blinks Quickly

The camera is transmitting a video resolution that is not supported. (For a list of supported resolutions, click here.)

 Air Unit – Network LED

On (White)

A link has been established to the Ground Unit.


The Air Unit is not broadcasting because it has not recognized any Ground Units with which it was paired previously.

Blinks Quickly

The Air Unit is pairing with a Ground Unit, or the Air Unit has gone out of range of the Ground Unit and is searching for it.

Blinks Slowly

The Air Unit is establishing a link with a Ground Unit.

Blinks Very Slowly

The Air Unit is searching for an available frequency on which to transmit.

Note: This may take up to 70 seconds when working outdoors in Japan.
