II. Precautions for integration
1) Be sure to use the parts provided by SUNTOR.
2) Reverse connecting power line positive and negative will burn the device out.
3) Before powering on please make sure the antenna are in good connection and not install or remove the
antennas with power on.
4) Given that the carbon fiber body and metal load may have shielding effects on antenna signals, they should not
be installed between the antenna and ground terminal. Keep the antenna on board free from winding or
blocking by obstacles. The antenna end should be vertically downward without bending to prevent shortening
communication distance and failure communication.
5) Antennas on board should be kept away from other radio antennas to avoid electromagnetic noise and
interference. We recommend to make full use of data and video transmitting function of ST30HPT to minimize
the radio devices quantity on board.
6) If using PTZ Camera, please do the PTZ self-testing firstly then connect HDMI cable.
7) HDMI cable and antenna on board may interfere with GPS. Please keep the HDMI cable and antenna away from
the GPS module and its cables.
8) Do not disassemble or modify SUNTOR ST30HPT. Any problem during installation, contact SUNTOR or SUNTOR
local branch office.
9) Keep appropriate distances between different electronic devices during installation to minimize the
electromagnetic interference.
10) Before using, please make sure all cables are in good connection and all components can work properly.

3rd
11) After starting the product, the self-test indicators of ST30HPT will continuously blink for 30s and then keep
bright. Only after the video from the camera shown on the display, then you can confirm that the device work
properly now.
12) Check the surrounding environment to ensure there is no other 2.4GHz devices to cause interference.
13) If you use the Futaba remote controller, the controller should be adjusted into the French mode. Otherwise, the
video transmission performance will be serious affected
14) Adjust the Futaba controller into French mode as following steps:
15) [LINKAGE MENU]→FRQUENCY→ RTN b→ [AREA]→[FRANCE]
Or connect ST30HPT S1 serial port with trainer interface on back side of Futaba by TTL cable. And set the Futaba RF
as OFF. Through the S1 port uplink the PPM/SBUS signal.
16) Before using, please check the power of RX and TX. If the receiver power off, transmitter on board will lose
connection.
17) Adjusting RX antenna inclination can improve the signal strength and image quality.
18) The camera should be fully charged to ensure normal video output.
19) ST30HPT support video and duplex data communication. If the video stuck or stopped for more than 10s. It
means the radio signal is weakened or the radio channel is narrowed. In this case, the aircraft need to fly back
to short the distance between TX and RX. Otherwise, the TX will lose connection.
20) Please use good electromagnetic shielding accessories(HDMI Cable, HD display and so on)
Notes: Improper operation of ST30HPT may cause personal injury or damage to properties. Please pay high attention
to operation safety.

failed
5Light 4 is Data connection light. If light 4 not bright, which means no data connection.
6When the transmission is normal, the WL light will normal on.
7After the receiver powered, the”POWER ON” letters will be showed on the display bottom right corner
5. Boot up successfully
After successfully connection, the display will smoothly show the image.
Remark: In UAV application, please make the connection successfully and the video show on ground station
smoothly then fly the UAV. About how to install the antenna on UAV please refer the following description.
VI. Antenna Installation
1. Multi-rotor UAV
1) Using SMA metal shielded semi-flexible blue feeder cable provided by
SUNTOR to connect the TX SMA port with antenna.
2) The antenna needs to be mounted vertically downwards.
3) The best installation location is UAV ground bracket. With
antenna inside, the bracket can only use fiberglass
material.
4) If the ground bracket is automatically retracted, the
antenna can be installed in the lower part of the aircraft.
5) If the antenna is intercepted by the camera or pod or the
loudspeaker, the video on RX will appear image stuck or
mosaic.
2. Fixed Wing UAV
1) Using SMA metal shielded semi-flexible blue feeder cable provided by SUNTOR to connect the TX SMA port with
antenna.
2) The antenna needs to be mounted vertically downwards.
SMA Feeder Cable

10th
3) The best installation position is center of UAV tail, prominent outside the body and vertical downward.
4) The second optional mounting position is located below the wing and body joints, vertical down, as far as
possible away from the wing but near the machine abdomen, protruding below the abdomen level.
VII. Software Operation
7.1. Two ways for changing the parameters
The parameters can be changed by software SUNTOR supplied such as bandwidth, code stream and so on. Two
windows for device on board and ground station can be operated at the same time to do monitoring or setting. The
SNR (db) / RSSI (dbm) will be updated in real time.
Notes：As for one pair of our devices, their parameters should be consistent, which means when you
change one of them, you have to change another one, or they will lose connection.
There are two ways to modify the parameters .
Solution 1. Connect Transmitter and Receiver separately to PC, then change their parameters one by one.

11th
Solution 2. Make sure communication between TX and RX is successful, connect TX with PC to changing another one
RX parameters by input its IP address firstly. After changing finsh, the communication will fail. Becasue the
parameters of TX and RX are different now. Secondly, change the TX parameters. After the changing is ok, the
communication will be successful again. If you connect the PC with RX, you need to change the TX parameters firstly,
then is the RX parameters.
7.2. How to use the software
7.2.1. Login
1Open the TDD software
2Inputthe IP address (TX Default IP: 192.168.55.1)( RX Default IP: 192.168.55.2)
3Next click Connect TDD button.

7.2.2. RF Configuration
Take TX as a sample, In RF Part, you can modify six parameters listed in
the following picture: TX Rate, TX Power, Channel Bandwidth, Channel
Frequency, Wireless Distance, TX-RX as the follow pic.
TX Rate (Default: QPSK FEC 1/2)
This setting determines the modulation type and rate that the data will be
wirelessly transferred.
‘Auto’ means the system will transfer data at the highest possible rate in
consideration of the receive signal strength (RSSI). Refer to Performance for a
table breakdown of performance at selected rates.
If setting a fixed TX Rate It is recommended to retain a fade margin of at least
10 dbm for optimum performance. For example, for a link (8MHz channel) with
a signal strength at least –75dBm, a TX rate of 16-QAM 3/4 FEC is
recommended. Setting to the highest rate with a poor link may result in
reduced performance.
Channel Bandwidth (Default: 4Mhz)
You can select the channel bandwidth from the list. Refer to the
specifications to see the relationship and performance between
channel bandwidth, throughput and sensitivity. Generally a larger
channel has greater throughput, at the cost of sensitivity, while a
smaller channel tends to be more robust, but at the cost of
throughput.

13th
Channel-Frequency (Default: 2479Mhz)
2402 - 2482 (1MHz BW, CH 1-81)
2402 - 2482 (2MHz BW, CH 1-81)
2405 - 2479 (4MHz BW, CH 4-78)
2407 - 2477 (8MHz BW, CH 6-76)
Wireless Distance (Default: e.g.,ST11HPT 10km)
The Wireless Distance parameter allows a user to set the expected
distance that the wireless signal needs to travel. The TDD-COFDM sets
various internal timeouts to account for this travel time. Longer
distances will require a higher setting, and shorter distances may
perform better if the setting is reduced.
RX-TX Mode
TX Master - A Master may provide a wireless data connection to many
slaves
RX Slave: A Salve may sustain one wireless connection,i.e. to an Master.

14th
TX Power(Default: 29dbm)
This setting establishes the transmit power level which
will be presented to the antenna connector of the
TDD_COFDM. Unless required, the Tx Power should not
be set into maximum, but rather for the minimum value
required to maintain an adequate system fade margin.
7.2.3. RS1 Configuration
In this section, you can modify two parameters listed in the following
picture: Data Baud Rate and Data Format
Data Baud Rate(Default: 115200)
The serial baud rate is the rate at which modem is to communicate with the
attached local asynchronous device.

15th
Data Format (Default: 8N1)
This setting determines the format of the data on the serial port.The
default is 8 data bits, No parity, and 1 Stop bit.
7.2.4. RS2 Configuration
This setting determines which protocol the serial server will use to transmit serial port data over the TDD-COFDM
network.
Remote IP Address
IP address of distant device to which UDP packets are sent when data
received at serial port.
Default: 192.168.55.2(master)
192.168.55.1(slave)

Remote Port
UDP port of distant device mentioned above.
Default: 20002

Listening Port
UDP port which the IP Series listens to (monitors).
UDP packets received on this port are forwarded to the unit’s serial
port.
Default: 20002

UDP Timeout(s)
UDP Timeout in second.
Default: 10
Character Timeout(ms)
Character Timeout in millisecond.
Default:10
Max Packet size
Default:1024
7.2.5. IP New Network Configuration
This setting helps you to change the IP address of devices. The default of master’s IP address is 192.168.55.1. The
default of slave’s IP address is 192.168.55.2

16th
For example, if you want to change the master’s IP address to
“192.168.55”. Please do as the following steps.
IP Set : 192.168.55.5
IP Mask Set: 255.255.255.0
IP Gateway Set: 192.168.55.1
Then click the IP NEW NETWORK button.
Attention! When you have changed the IP address ,you should correct
another device ‘s “Remote IP Addr” into the same “IP SET”, or the serial
port will lose connection.
For example , you have changed the master’s IP address to “192.168.55.5”
the you should correct the salver’s “Remote IP Addr” to “192.168.55.5”.
7.2.6. RF New NET Configuration
RF Net ID:
Each network of TDD-COFDM modules must have a unique Network
ID. This Network ID must be set in each unit on the network.
RF Encrypt KEY
This is the password, or preshared key that is required by any device
to connect to the wireless interface of the TDD-COFDM. It is to
always have a password defined, and changed from the factory
default.
After you change the ID or the RF Encrypt Key, you need click the RF
NEW NET to save the changing.
Note: After many times chaning parameres, the software will be unstable. Then you need to click the RSETTDD
Button to restart the software. After restart, the software will be very stable.
