Matters Need Attention
1. The ability of penetrating of radio signal from 2.4GHz wireless data-link is weak;
please make sure the antenna of it is always visible to the ground end during the flight.
Human body, trees, buildings or hills will stop the communication between air end and
ground end.
2. You‟d better put the ground end at high place. This can guarantee a good
communication range.
3. Make sure the antenna head of air end is erect down, and the antenna head of ground
end is erect up. Make sure there is no obstacle between antennas; otherwise the
communication range will be reduced.
4. Ground end Link-Alarm red light on is distance alarm, red light off is safe. When it is on,
you‟d better return your aircraft.
5. When ground end Link-Alarm green light is off, this indicates the communication
between ground end and air end is off, whatever the state of red light.
6. Make sure the driver is installed correctly.
7. Please choose the right com port.
8. Check out the power supply of wireless data-links before use.
9. Please close the DJI assistant software before open the ground station. Otherwise
there will be port conflict.
10. Make sure the distance between 2.4GHz ground end and air end is over 1.5m; the
distance between 900MHz ground end and air end is over 5m.
11. Use the right cable for connection.
12. High voltage servos & FBL systems can drain the flight battery fast. Please make sure
your flight pack is sufficient for the flight time intended.
13. About control modes (Manual, Atti., GPS Atti., GPS Cruise), please refer to ACE
Control Modes in ACE Waypoint User Manual and WKM Control Modes in WKM User
Manual.
14. Autopilot Mode (auto mode) means: GPS Atti. or GPS Cruise Mode in ACE; GPS Atti.
Mode in WKM.
If you have any problem you cannot solve during installation and usage, please contact our
customer service.

Connection
Antenna
Head
Ground End
· You should have a DJI Ground Station installed laptop.
· Use the USB Cable supplied by us to connect the wireless data-
link ground end to you laptop. One end of the USB cable has two
heads, make sure the communication interface is plugged into
your laptop. If the power supply is insufficient using one USB port,
then plug the power interface Into the laptop also.
Air End
· 900MHz wireless data-link air end has two CAN ports. When you use it with ACE autopilot
system and low voltage servo, you should connect one CAN port to sparE CAN port on
autopilot system, and connect another one to a battery whose output voltage is in the range
of wireless data-link air end working voltage.
· 2.4GHz wireless data-link air end has only one CAN port.
· Usually connecting one CAN port on air end to any spare CAN port on DJI autopilot system is
enough.
· WKM user should use it with PMU.
· High voltage servos & FBL systems can drain the flight battery fast. Please make sure your flight pack
is sufficient for the flight time intended.
· Make sure the antenna head of Wireless data-link air end is erect down, then you can have the
largest range.

(2)Altitude Offset Setting
GIS database (Google Earth™) is not precise, while Flight Path Mountain and other obstacle/building
collision checking feature performed based on this database, which is not real-time or up-to-date.
Google Earth™ plug-in is only for the purpose as a general landscape browser, for quick way points
positioning without much safety guarantee.
Pressure sensor is used for altitude sensing, leading the result varies according to weather. Therefore,
you might have different altitude values on the same location at different times. However, its relative
height may be far from precise than absolute altitude information in GIS.
Due to above problems, the following method for relative flight height calculation would be most reliable.
1) Record the aircraft altitude before take-off, as LGound
2) Way point altitude = Relative Flight Height + LGound
Please keep in mind that this method is the most reliable way for flight path collision precaution.
The Altitude Offset value given is only for the purpose to avoid visual confusion, such as Case 1 in fig.①
shown below. The aircraft represented by the red point was located on the ground in real world but
floating in the sky within 3D-Map. You have to give a negative offset value to reduce the aircraft altitude
for visual effect only. The calculate altitude offset function will give you a suggestion for offset setting but
not guaranteed to be correct. Because if the aircraft is landed on the roof of the building as in Case 2 in
figure shown below, and the building information will not appear in GIS database, which means you
cannot use the same method as in Case 1. You should calculate this offset value with a known or
estimated building height.
Tips:
We highly RECOMMEND you to consider the relative flight height discussed during flight mission editing.

2 Joystick/Keyboard Mode
Joystick/Keyboard mode is the 2nd permission for users, and Fly Simulation, One Key Takeoff and Joystick/
Keyboard functions can be operated.
2.1 Simulator
Pre-Flight Simulation aims to help you getting familiar with the Ground Station software. A successful flight
under simulation mode does not guarantee your aircraft to work successfully in real world, since it is only a
virtual environment based on the assumption that your aircraft is working under perfect condition with infinity
power supply, favorable weather, and also that the GIS & GPS are providing 100% correct and precise
information. The aircraft physical model in simulator might not perform the same flight characteristic as your
real aircraft.
Notices:
ENSURE the following requirements whenever during/before Simulation Mode:
1) You MUST NOT take off your aircraft.
2) You MUST NOT turn on your aircraft engine/motor.
3) You CAN disconnect the power supply for electric motor, or disconnect the throttle control servo
motor for fuel engine. Otherwise, incorrect operation could result in serious personal injuries.
Please follow the steps strictly for Simulation Mode use:
STEP1 Connect the whole main control system completely, including IMU、GPS, etc.
STEP2 Hold Ctrl then Right click, you will see simulate, and the aircraft logo will be at the current
mouse position.
STEP3 Click simulate, you will see a “Warning” window.
STEP4 Click Yes to turn on Simulate Mode. Now GS is in Simulate Mode!!!
Notices:
We HIGHLY RECOMMEND Simulation Mode for practicing purpose for flight mission edit, try to get
familiar with all the operations of your Ground Station as much as you can.
The simulation model requires a complete main control system connection, and you can reference
to Assembly in DJI autopilot system user manual.

2.2 One Key Takeoff
Notices:
One key takeoff is a function especially for WKM, that can be used only in autopilot mode and when GPS
signal is good.
Messages may be showed as follows:
Successful takeoff message
"The aircraft is auto Takeoff!"
Error messages
"Auto Takeoff failure, GPS is not ready!"
“The aircraft is Takeoffing!"
"Auto Takeoff failure, the aircraft is already flying!"
"Auto Takeoff failure, please switch to auto mode!"
