6. Notes
6.1.Link performance
Interference by 2.4GHz WiFi
WiFi operates at 2.4GHz band with bandwidths of 20MHz and 40MHz. WiFI can generate both
co-channel interference and adjacent channel interference to the 2.4GHz wireless link of a
drone. Even if there is not a WiFi router is available for a WiFi device (for example, WiFi of a
phone) to connect with, a WiFi device periodically transmits beacon/probe signals. So, when
you operate a drone in the field with 2.4GHz wireless link, it is important to turn off WiFi
modem/hotspot of a phone, or a laptop. If WiFi relay of the video from the ground station is
desired, it is recommended to use a 5.8GHz WiFi modem.
Interference by Bluetooth device
Bluetooth operates on 2.4GHz in frequency hopping mode. So a Bluetooth mouse, Bluetooth
joystick, or any Bluetooth device that is actively working and next to ground station will
interfere the reception of downlink video. Please avoid using Bluetooth device when operate a
drone with 2.4GHz wireless link.
Interference by wireless device in co-existence
Page 37
34
Another wireless device that operates on bands close to 2.4GHz and the device is placed close
to the drone’s 2.4GHz wireless module can interfere the drone’s wireless link. For example,
some drones have both LTE link and point-2-point wireless link. Particularly, the LTE
operating on 2.3GHz band can be a problem. If the antenna of the LTE module is placed close
to the antenna of the 2.4GHz point-2-point wireless module, the receiver of 2.4GHz module can
be saturated by the LTE signal when it is transmitting. Thus, the range/performance of the
2.4GHz module will be significantly degraded.
Interference by HDMI
When HDMI source/cable is close the antenna of 2.4GHz wireless modem, the HDMI
source/video will interfere the 2.4GHz wireless signal (including WiFi).
https://h30434.www3.hp.com/t5/Notebooks-Archive-Read-Only/HDMI-interfering-with-WiFiconnectivity/td-p/4535026
http://www.dslreports.com/forum/r27141612-HDMI-connect-interferes-with-wifi
It is recommended that install the antenna at least 25cm away from the HDMI source/cable. A
good shield HDMI cable can be a resolution too. The following shield HDMI cable uses 360degree shield termination, which is recommended practice.

http://www.l-com.com/audio-video-micro-hdmi-to-hdmi-cables
http://www.l-com.com/audio-video-hdmi-female-to-micro-hdmi-male-adapter
RF cable connector/Antenna connector check
Before flight, check if the antennas are connected to the modules. Running module without
antenna connected results in very short range and potentially can damage the module. It is
recommended to check the connection of all RF connectors. Loose connection can degrade the
range significantly.
Antenna placement
Page 38
35
Place the two air antennas so that no matter what position the drone is, at lease one antenna is
not blocked by the payload from the ground station.
If the drone will fly in full throttle, it will lean forward. Install the air antenna so that it is close
to be vertical to the ground when the drone moves forward in full throttle.
Battery level of ground station
The reception performance will degrade if the battery of ground station runs low, even though it
might still power the wireless ground unit up.
6.2.How to select Frequency
Click “Frequency” buttion using Viulinx APP.
On the left, you can see the RSSI curve of frequency scan.
Scan range: 2.4G WIFI bands.
The lower the RSSI value of the corresponding frequency points, the lower interference.
Please select the lowest interference frequency.
Page 39
36
Working Mode：Manual, Auto.
Manual mode: The module administrator or user manually configures the operating frequency.
Auto mode: The management software configures the optimal working frequency according to
the frequency scan information.
Please make sure working mode is on manual mode.
Page 40
37
We can select working frequency by band selection function.
We provide 2390MHz and 2495MHz reserved frequency.
If WiFi interference is too high, you can consider using reserved frequency.
6.3.Firmware update
Upgrade files: FPGA upgrade file for air unit, FPGA upgrade file for ground unit, MCU1
upgrade file for air unit, MCU1 upgrade file for ground unit, MCU2 upgrade file for air unit,
MCU2 upgrade file for ground unit, Hi3516 upgrade file for air unit, Hi3798 upgrade file for
ground unit.
Hi3798 upgrade file for ground unit is upgraded with U disk. The fastboot. bin file needs to be
added to the root directory of the U disk, and the upgrade file is renamed update. bin. When the
ground unit is powered on, insert the U disk into the USB port. The LED lamp of the ground
unit will appear green flashing, indicating that it is in the upgrade process. When upgrade is
completed, the LED lamp will no longer flashing. The upgrade process is expected to last 7-8
minutes.
Page 41
38
Other files are upgraded using management software. During the upgrade process, the power
can not be powered off and the normal connection of USB cable should be ensured at the same
time. If the upgrade fails, the power can not be powered off, please try to upgrade again
directly. Otherwise, it will be necessary to return to us to use special burning tools for firmware
burning.
6.4.Bind operation
“Bind” is used to pair an air unit with ground unit.
To pair an air unit and an ground unit:
1. Both air unit and ground unit are powered on.
2. Connect the air and ground unit.
3. Press the physical bind button of the air unit, last 3-5s. The LED light next to the bind
button flashes green, indicating that it is in the binding state.
4. Press the physical bind button of the ground unit, last 3-5s. The LED light next to the
bind button flashes green, indicating that it is in the binding state.
5. When the link indicator LEDs of ground unit are always on, it indicates that the air
and gournd unit is binded. Then power off both units.
6. Power on both units. Link indicator lights are always on, indicating bind operation of
the air and ground units are completed.
Note:
(1) If modules binding with different firmware version, the binding operation may fail.
(2) If the program of the air unit or the ground unit is burned incorrectly, such as burning
the air unit to the ground unit, and performing the binding operation between the wrong
air unit and the ground unit, the binding operation will fail.

Q10: There are some devices nearby, such as WIFI, Bluetooth and so on. Can they be opened
when flying?
Be sure to turn off WIFI, Bluetooth and other functions of other devices, because these
devices are working in 2.4 GHz band, It can cause interference.
Q11 After integrating the Taisync air unit, GPS is not good at searching for stars. What
should we do?
Please check whether the antennas of air unit is far away from GPS to avoid blocking
interference to GPS. The frequency band of 1.4G module is close to working frequency of GPS, so
it is necessary to ensure a certain degree of antenna isolation.
Q12: What do the two LED lights of the ground unit stand for?
LED 1 (downlink Indicator): The LED is on indicates that the air-to-ground link is connected;
the LED is not on indicates that the air-to-ground link is disconnected.
LED 2(uplink Indicator): The LED is on indicates that the ground-to-air link is connected; the
LED is not on indicates that the ground-to-air link is disconnected.
Q13: What if the uplink LED indicator is not on?
Please follow the following steps:
1) Please check the power supply of the air and ground unit is normal.
2) Please check the antennas installation of the air and ground units is normal: whether the
