Pairing Air Unit and Controller

Controller and Air Unit Pairing Instruction
Initial Pairing:

1. Power on and unlock the controller. A warning will be shown as below:
2. At the same time within 30s, long press the [Pair/Reset] button for 3s on the air unit to make the air unit enter pairing mode (air unit Pair/Reset is as shown below):
3. Wait and observe QGC on the controller side. If pairing is successful, it will pop up calibrate succeed. Click [OK] to complete the code matching process. If calibrate failed pops up, please restart the process.

Re-pairing

1. Click on [Q] icon on the controller
2. Click [D2D Info] to enter pairing UlI
3. Click [Calibrate] to stat pairing

Getting Video Stream to Work

1.  After pairing is completed, the air unit and the controller are connected successfully. Connect the air unit HDMI, turn on 1080P video input source in “Video Stream Settings” (refers to P12). The video will be displayed at the lower left corner of QGC. Click the video frame to display in full Screen.
2.  Problems that mav arise during transmission.
3. Q1: Why is there no video transmission after the camera is connected to Herelink via HDMI? Meanwhile the controller screen shows “WAITING FOR VIDEO” and video stream at the upper right corner is changing arounda few kbps? Solution: Check it HDMI output resolution is 1080P (QGC resolution setting must be consistent with camera resolution setting). Please also check HDMI connection, or replace the HDMI cable with a new one.
4. Q2: The link rate in the upper right corner display Okbps Solution: Re-Dair or restart machine.

Video Stream Settings
Click on the airplane icon at the upper left corner and select Video Stream] from the drop-down menu on the right.

1. Rate: Configure link rate (related to environment and current working mode)
2. Stream 1: HDMI 1 (closer to power supply interface)
3. Stream 2: HDMI 2
4. Enable Stream: Turn on/off video display

D2d Info Settings
Click on Qicon in the upper left comer and select D2d Info:

• X-axis: Frequency. Red line represents the current working frequency
• Y-axis: SNR (signal-to-noise ratio). The larger the value is, the smaller the interference is.

1. Upstream working bandwidth:

2. UL_1.4M/UL_10M/UL 20M/UL_L4M/UL_1OM/UL_20M 20M for less interference scenarios and long distances. 1.4M for multiple interference scenarios.

3. Downstream working bandwidth: DL_10M/DL_20M 20M for less interference scenarios and long distances. 10M for multiple interference scenarios.

4. Current working requency

5. Current working bandwidth SNR value

6. Confirm current setting

7. Manual Mode (Frequency Configurable Mode): User select working requency according to the current environment.
   Manual input frequency range is as follows:

   • Upstream working bandwidth 10M corresponds to 47050-47785
   • Downstream working bandwidth 20M corresponds to 47100-47735

8. Auto Mode (Frequency Hopping Mode):
   It is recommended to work in this mode to automatically select the best working freauency.

Important Notes

1.  Ifyou connected a GoPro 6 Black and disconnect it before video is connected to the air unit, the hot swap may result in no video output from GoPro. It is suggested to restart your GoPro or place the GoPro upside down to have the image back.
2. Air unit power input: 5V-12.6V max (3s Lipo supported). Any power range above that will burn the device.
3.  The temperature will rise when the air unit is connected with the controller. Temperature of the air unit can be checked on the controller side, and should be lower than 70 degrees. (lf the temperature rose over 70 degrees, installing a fan should be considered.

FAQS

1. Can language on the controller be switched?
   The system language can be switched in slide down menu, but QGC is default as English and cannot be switched.

2. Why aren’ t the LEDs lit, even though the air unit are properly correctly connected?
   Check the power input. It should be 5V – 12.6V max (3s Lipo supported) and battery should have been charged.

3. Why can’t connect to 2.4GHz WIFI?
   Currently, Herelink only enables 5.8GHz WIFI for internet connection. Therefore, to load maps, you will need to connect to a 5.8GHz WIFIl network.
