A single Air Unit can transmit video downlink to up to four Ground Units. This is called multicasting. The following procedure describes how to pair an additional Ground Unit with the same Air Unit.

Note: 

  1. The Air and Ground Units provided in the same box are preconfigured to automatically search for and connect to each other. Therefore, there is no need to perform this procedure on the Air Unit / Ground Unit provided in the same box.

  2. Controlling the Air Unit's camera gimbal is not recommended when the Air Unit is registered to more than two Ground Units (even if only two of the registered Ground Units are powered ON).

  3. Register one Ground unit at a time to each Air unit. 

Pairing Additional Ground Units with an Air Unit

To pair an additional Ground Unit with an Air Unit:

  1. Set up the additional Ground Unit, as described in Setting Up the CONNEX Ground Unit or Setting Up the CONNEX mini Ground Unit.

    The Ground Unit must be placed between one and 10 meters from the Air Unit. Each Ground Unit must be placed at least a few meters away from other Ground Units in order to enable optimal reception.

    The following message is then displayed on the monitor connected to the Ground Unit’s HDMI port:

          "Ground Unit not registered to Air Unit."

  2. Press and hold the Link button on the Ground Unit (for approximately five seconds) until its Network  LED starts blinking. The following message is displayed on the monitor connected to the Ground Unit:

         "Please activate registration on Air Unit."

  3. Power on the Air Unit with which to pair this Ground Unit. This step assumes that the Air Unit has already been set up, as described in Setting Up the CONNEX Air Unit or Setting Up the CONNEX mini Air Unit.

    Press the Air Unit’s Link button for approximately five seconds until the Network LED starts blinking. After the LED begins blinking, the following message is displayed on the monitor connected to the Ground Unit.

        "Air Unit detected. Please press the Link button."

  4. Press and release the Link button on the Ground Unit (do not press and hold). The following message is then displayed:

         "Pairing in progress."

    After a while, the monitor connected to the Ground Unit should display the video received from the Air Unit.

    Note: If a black screen is displayed, check that the camera on the drone is operating.

To see a list of Ground Units with which an Air Unit is currently paired and connected, you may use the CONNEX Management application to check the Ground Units that are registered to an Air Unit. For more information, click here for Windows / MAC and click here for Android devices.

To clear Ground Units with which an Air Unit is paired, you may use the CONNEX Management application to unregister Ground Units. For more information, click here for Windows / MAC and click here for Android devices.
