This section describes how to set up the CONNEX mini 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 mini Air Unit:

  1. Attach the Air Unit to the drone, using the velcro squares provided. The Air Unit may be mounted to a bar or to a flat surface, and then secured with plastic ties.

  2. 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

    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.

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

  4. Connect the provided Micro to Micro HDMI cable from the HDMIIN port on the Air Unit to the camera.

    Micro to Micro HDMI Cable

    One side of this cable goes into the Air Unit's HDMI IN port.

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

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

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

    The left side of this cable goes to the battery.

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

  7. 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:

    • If video is transmitting, the Ground Units display the video.

    • If video is not transmitting, the Ground Units display the message: Video signal not detected.

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

  8. [Optional] To display information received from the drone's flight controller overlaid on the video on the Ground Unit monitor, refer to Connecting the CTRL Port for MAVLink Telemetry (CONNEX mini) or Connecting the CTRL Port for CAN bus Telemetry (CONNEX mini)

LED Behavior

The CONNEX mini features two LED indicators: a Video LED and a Network LED. In normal operating conditions, both LEDs show a constant white color. No power (or low power) is indicated by the LEDs turning off.

When the LED indicator is blinking quickly (in either LED), a system error has been detected. In this case, use the CONNEX Management application to update the software, or contact CONNEX support.

The behaviors of each individual LED are described in the tables below.

Air Unit – Video LED

Solid

The video signal from the camera is locked, meaning that it is being correctly received by the Air Unit from the camera. (This does not necessarily indicate that a link exists.)

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 by the Air Unit. (For a list of supported resolutions, click here.)

Air Unit – Network LED

Solid

A link has been established to the Ground Unit, meaning that video is being transmitted to it (all of the receivers are powered on and in range).

Blinks Quickly

Registration is in progress, or the Air Unit has gone out of range of a 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.

Off

No broadcasting is occurring.
