Controller Antenna Assembly and Disassembly

• To assemble the antenna, plug the Omni-directional antenna into the top left hole of the controller and rotate it to align. Then press and rotate the clockwise lock.
• Plug the directional antenna into the top right hole of the controller and rotate to align. Then press and rotate clockwise to lock.
  Disassemble antennas by pressing and rotating COunter-clockwise. Then they can be pulled out. (Left is for the Omnidirectional antenna; the right is for the directional antenna).

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 below:
2. At the same time within 30s, long press the [Pair/Reset button tor 3s on the air unit to make the air unit ente 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 tailed pops up, please restart the process.

Re-pairing:

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

Then repeat Step2 and Step3 of “Initial 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, and turn on the 1080P video input source in “Video Stream Settings” (refers to P12). The video will be displayed in the lower left corner of QGC. Click the video frame to display in full Screen.
2. Problems that may arise during transmission

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 the video stream a the upper right corner is changing around a few kbps?

Solution:
Check if HDMI output resolution is 1080P (QGC resolution setting must be consistent with camera resolution setting). Please also check the HDMI connection, or replace the HDMI cable with a new one.

Q2: The link rate in the upper right corner display 0kbps

Solution:
Repair or restart the 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. Stream1: HDMI 1 (closer to power supply interface)
3. Stream 2: HDMI 2
4. Enable Stream: Turn on/off the video display
5. 1080P Video: Choose between video resolution. When the radio button is on: 1080P; off 720P.
6. Grid Lines: Grids on video display
7. Record Stream: Recording switch

D2d Info Settings

Click on the Q icon in the upper left corner and select D2d Info

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

1. Upstream working bandwidth:
   UL_14M/UL_1OM/UL_20M

   • 20M for fewer interference scenarios and long distances.
   • 1.4M for multiple interference scenarios.

2. Downstream working bandwidth:
   DL_10M/DL_20M

   • 20M for fewer interference scenarios and long distances.
   • 10M for multiple interference scenarios.

3. Current working frequency

4. Current working bandwidth SNR value

5. Confirm current setting

6. Manual Mode (Frequency Configurable Mode):
   Users select working frequency according to the current environment.

   • Click Manual Mode, it will pop up “succeed”. Then enter the target frequency manually in the red box as shown below, or touch the graph to select. Click OK to confirm.

The manual input frequency range is as follows:

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

After setting, Ul will pop up “succeed”. This means target frequency value, which is 47751, has been set. This value is for reterence only, the actual working frequency should be set according to the environment of its own use)

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

Important Notes

1. If you connected a GoPro 6 Black and disconnect I before the 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 to the controller. The temperature of the air unit can be checked on the controller side and should be lower than 70 degrees.

(If the temperature rose over 70 degrees, installing a fan should be considered.)

FAQS

1. Can the language on the controller be switched?
   The system language can be switched in the slide-down menu, but QGC is defaulted 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 the 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 WIFI network.
