1. Brief introductions for GCS
FY-31AP GCS is similar to Panda GCS, the main functions include
electronic map、telemetry data monitoring、flight attitude instrument、speed,
altitude instrument, location, and telemetry data recording and playback, air
route editing, map loading management etc. Brief introductions for the
GCS of FY-31AP are shown as below.
Software operating environment:
CPU frequency: 1GHz or more
Memor y capacity: 1G or more
Hard disk space: At least 200MB free disk spac e
Operating System: Windows XP, Vista, Win 7 etc
Monitor: 1024x768 resolution or above
The computer Serial Port: Support USB serial converter or 9-pin port which
baud rate is 19200 or more
Other Peripherals: Keyboard, Mouse
2. The installation of GCS and USB-TLL
Firstly, you should download the GCS and USB-TLL serial drive on our
official website: www.feiyudz.cn.
FYGCS 2D 4.0 version download link:
http://www.feiyu-tech.cn/download.php?id=47
USB-TTL serial drive download link:
http://www.feiyu-tech.cn/download.php?id=35
After download the program please click install.Suggestions install all the
way by default. Or choose the right path. Path had better not choose
desktop, path don't with Chinese, blank space or strange characters, path
not too deep.
Open the GCS, you can see the following interface.
（If you can’t open the GCS in Vista or Win7 system, please find out the
executable file, and run it as the administrator.）
Step 1: install the USB-TTL serial drive
1) Double-click the serial drive, installed by default.
2) Restart the computer and make the drive be activated.
3) If it can't be used, please uninstall the original drive and reinstall this one,
or search its PL2303 chip to the latest version on the Internet.
Step 2: confirm the USB-TTL Virtual serial number (take Win XP for example)
1) Insert the USB-TTL interface cable into computer USB COM port(don’t
connect TTL port to any other wire ) , you will find there is more than
one port(COM and LPT), the port“COM1”in the “Prolific
USB-to-Serial Com Port (COM1)” exactly is the Virtual serial number.
2）inserter a few times for confirmation
3）Modify the serial number if necessary
3. Hardware connection instruction
FY-31 AP provides a data radio interface (UART), you can downlink
telemetry data and receive control information by radio and monitor the real
time flight by the computer. The telemetry data includes: Longitude, latitude,
altitude, speed, heading, positioning, operation mode and the real-time
output amount of the servo and so on. By matching with remoter adapter,
you also can send the receiver signal to FY-31AP module by the radio to
achieve remote control. By matching the GCS, it can real time display flight
trace and flight parameters. In addition, you can conduct pointing flight, or
change flight attitude in real time and circling radius and so on.
Note: FY -31AP telemetry data default frequency is 10hz, because
downloading frequency is too high. Use half duplex radio (such as FY -
602, FY - 605) will give the computer brings great burden, cause GCS is
not able to use or extremely slow. If you need to use our GCS for
real-time monitoring. We strongly recommend that you should change
the telemetry data frequency to 1hz, remote data frequency to 10Hz,
avoid to cause computer burden, And influence the normal use of our
software.
If you just connect with Hornet - OSD to realize FPV, And you do not
need to use GCS to real-time monitoring, Then you do not need to
change the frequency.
Frequency modification method:
Connect the FY-31AP to the computer directly for setting (shown as
below)
(In order to let your FY-31AP can success connect to the GCS to
change the frequency, For protection measures. FY-31AP firmware More
than V1.20 , the first 10s FY-31AP will automatically change data output
frequency into 1hz.After 10s will automatically be back into the default
10hz.)
FY-31AP connection options
A. Use the data radio to connect to FY-31AP.
You can use a pair of data radio to realize wireless setting. It is
convenient to debug, and you can upload air route at any time. You also can
realize the function of monitoring flight attitude and flight trace. You can fly
to anywhere on the map or change flight attitude by using FY GCS.

B. Use the data radio and Remote Adapter to connect to FY-31AP.
In this way, you need not connect to RC receiver. The remote adapter
transforms the signal offered by RC receiver into digital data, The signal
would be transmitted to FY-31AP by data radio. You can not only set the
value at any time via data radio, but also extend the remote distance, this
distance is determined by the radio communication distance. As a result, you
can realize FPV for farther distance easily. Without receiver, the connecting
would be simple, but there will be some delay when you control the flight.
Show as following:
C. Use two receiver system
use two same frequency receiver one installed in the Remote Adapter,
another is installed on the aircraft. Such use is the premise of the two
receiver can be operated at the same time by RC, and two receiver , FY-31AP
and Remote Adapter connection must correspond to the channel. During
the operation FY-31AP can only receive one receiver signal, through GCS
"RC" (or "DRRC") button to switch.

Remote adaptor introduction
The main function of remote adaptor board is to send the digitalize
output signal of the remote rec eiver to FY-31AP through data radio, at the
same time send the control instructions of the GCS to FY-31AP through data
radio, and send the flight trace and flight parameters which sent back by
FY-31AP to GCS. Remote adaptor board includes the port with receiver, the
port with data radio and the port with PC, the typical connecting diagram is

4. FYGCS 2D 4.0 Ground Control Station Software
Note: in the connection of a complete set of ground station system,
device power on principle is to power the ground station ’s device first,
when data radio(which on the ground) and remote adapter success
power on, then power on the FY-31AP. In order to prevent the data radio
send too much information , cause congestion, so that the ground
station system can't use normally.
1) Double-click“ ”, installed by default.
2) After installation, double-click “ ”, open the FYGCS 2D Beta,
you can see the following interface.
Fig1 FYGCS 2D 4.0 Main Interface
3) Click “open”menu bar in FYGCS 2D 4.0 main interface, loaded the
electronic atlas of the MapInfo format (*. gst files) into the map window
of the software. As following:

5) Insert the USB-TTL cable into computer, confirm the USB-TTL serial
number, and click “Connect”. Please save the record file, this file can
record data of flight.
Fig5 Connect Display Interface
Note:
(1)Frequency setting
You can set the output telemetry data rate by choosing “Tel Rate”, the
higher setting value is, the faster rate will be. It can help to improve the
refresh rate of OSD data overlay and GCS display data. But the value can’t
be set too high, because of being limited by communication rate when using
data radio. Otherwise the large output data will block the communication.
When connect to remote adapter, “RC Rate” is used to set the upload
link data rate. The higher setting value is, the better real time telemetry data
will be. But the value can’t be set too high, because of being limited by
communication rate when using data radio. Otherwise the large output data
will block the communication.
Settings Suggest:
Half duplex radio(Such as FY-602,FY-605)
When using the data radio, and connecting the RC receiver to FY-31AP
directly, “Tel Rate” should be 1HZ;”RC Rate”should be 10HZ.
When using the data radio, and connecting the RC receiver to remote
adapter, you need not set the frequency and the “Tel Rate”will turn to 1HZ
automatically.
When without the data radio, and connecting to OSD, the “Tel Rate”
could be 10HZ. It will help to improve the refresh rate of data overlay.
Full duplex radio(Such as FY-606)
You don’t need to change the frequency,just use the default frequenvy.
(2)Because FY-31AP has three way connect to the GCS:
A：
RC Receiver directly connect to the FY-31AP,you need choose “RC”and
“RC enable”in our GCS.Like the below picture shows:
B:
RC Receiver connect to the Remote Adapter on the ground,you need
choose“DRRC”and“RC Enable”like the below picture shows:
