and accessories, such as the radio power amplifier, antenna and SMA extension cord).
Notes: Improper operation of ST5/11/30HPT may cause personal injury or damage to properties to some
extent. Pay attention to operation safety.
II. Precautions for integration
1. Be sure to use the parts provided by SUNTOR.
2. Please not reverse connect power line positive and negative. Or the device will be burn out.
3. Install the antenna before power on. Please not install or remove the antenna with power.
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 of the on board
terminal free from winding or blocking by obstacles. The antenna end should be vertically downward
without bending, to prevent shortening of the communication distance and failure in communication
as a result of blocking.
5. The antennas of the onboard terminal should be separated from each other to achieve good
anti-jamming effects. It should be kept far away from antennas of other onboard radio transmitters, as
huge electromagnetic noise and interference may be caused between various radio antennas, which
will seriously shorten the communication distance, reduce the reliability of communication and even
cause failure in communication. It is recommended to use the functions of SUNTOR product, i.e. image
transmission and RS232 two-way serial port communication to minimize the quantity of onboard radio
devices.
6. Use the antenna of specified type, and properly install it. It is prohibited to use antennas of other
types.

7. To directly use the HDMI output of the PTZ camera, connect the PTZ holder after energizing and
self-testing, to avoid damage caused by rotation of the PTZ holder in self-testing to the HDMI cable. To
thoroughly solve this problem, it is preferred to use the split product, that is, the HDMI RX video
encoder board and PTZ camera are integrated with a short distance, and separated from the Ethernet
TX via the 4pin 100Mbps Ethernet cable. In this case, the reliability of HDMI signals between the PTZ
camera and HDMIRX video communication board will be greatly improved.
8. The HDMI cable and antenna may cause interference to GPS. They should be kept far away from the
GPS module and its cables as much as possible in the wiring process.
9. Do not disassemble or modify SUNTOR ST5/11/30HPT. Any problem during installation, contact
SUNTOR or the sales agent.
10. Keep appropriate distances between electronic devices during installation to minimize electromagnetic
interference.

IV. Interface
Remark: The TX and RX have same interface specifications, All references are given above.
V. Precautions When Powering On
1. Before using, make sure that all cables are secure and reliably and all components can work properly.
2. After starting the product, check it for proper operation by observing whether the self-test indicator of
ST-3500HDis continuously ON for 30s and then flicker and whether the image of the camera is shown
on the ground terminal.

3. Check the surrounding environment for to ensure there is no other 2.4GHz devices to cause
interference. If use the Futaba remote controller, the controller should be adjusted into the French
mode. Otherwise, the video transmission performance of ST5/11/30HPT may be serious affected and
also the Futaba transceiver may be in the abnormal status and accidents may be caused.
4. Remark: How to adjust the Futaba controller into French mode:
[LINKAGE MENU]→FRQUENCY→ RTN b→ [AREA]→[FRANCE]
5. Before use, check the electric quantity of the ground terminal. If the ground terminal is OFF, the
built-in radio receiver of the onboard terminal will be out-of-control.
6. Pay attention to the angle and direction of the antenna of the ground terminal during flight. In case of
poor signal or image quality, adjusting the inclination of the antenna of the ground terminal can
improve the signal or image effect.
7. The camera should be fully charged to ensure normal video output.
8. ST5/11/30HPT has the functions of two-way communication of image data and serial port data. If the
transmitted ground image is stuck or stopped for more than 10s but less than 30s, it means that the
radio channel signal is weakened or the radio channel is narrowed. In this case, the aircraft must not fly
farther away from the ground. In order to ensure the normal communication of serial data and the
safety of the aircraft, the distance between the aircraft and ground terminal should be immediately
shortened. Otherwise, the built-in radio receiver of the onboard terminal will be out-of-control.
9. 8. If required, purchase electronic devices (such as HD displays, Network cables, etc.) with good
electromagnetic shielding effects.

Remark: In UAV application, please make the connection successfully then fly the UAV. About the right way of
installation antenna please refer to the following description.
VII. Antenna Installation
1. Multi-rotor UAV
1) To select the original antenna and the SMA metal shielded semi-flexible blue feeder cable provided by
SUNTOR. The feeder cable is used to connect the TX SMA port and the antenna.
2) The antenna needs to be mounted vertically downwards, and it
is not recommended to mount it vertically at the top of the UAV.
3) The best installation location is the UAV ground bracket. With
the 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, and the ground RX
antenna is recommended to use same antenna with TX( 29cm
length antenna).
5) If the antenna is intercepted by the camera or pod or the loudspeaker, the video on RX will appear
image stuck or mosaic and It is recommended to immediately adjust the flight attitude and angle.
2. Fixed Wing UAV
1) To select the original antenna and the SMA metal shielded semi-flexible blue feeder cable provided by
SUNTOR. The feeder cable is used to connect the TX SMA port and the antenna.
2) The antenna needs to be mounted vertically downwards, and it is not recommended to mount it

vertically at the top of the UAV.
3) It is recommended to use 29cm long antenna. The best installation position is the center of the 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.
VIII. Software Operation
1. Start Connecting Tdd-cofdm equipment
First, enter the IP address，Next click Connect TDD button.
2. Restart TDD-COFDM Control Panel software:click Restart TDD button.
3. RF Configuration method
3. 1. TX Rate（Default：QPSK FEC 1/2）:
This setting determines the modulation type and in turn the rate at which the data is to be
wirelessly transferred. The default and recommended setting for both Master and Slave
units is ‘Auto’. When in ‘Auto’ the unit 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

9th
performance. For example, for a link (8MHz channel) with a signal strength of 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.
3.2. Channel Bandwidth（Default：4Mhz）:
Select the channel bandwidth from the list. Refer to the specifications to see
the relationship and performance between channel band, width,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.
3.3. 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)
3.4. Wireless Distance（Default：10km）:
The Wireless Distance parameter allows a user to set the expected distance 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.

10th
3.5. 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.
3.6. TX Power（Default：30dbm）:
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 be
set not for maximum, but rather for the minimum value required to maintain an
adequate system fade margin.
4. Seria Configuration method:
4.1. Data Baud Rate（Default：115200）:
The serial baud rate is the rate at which the modem is to communicate with the
attached local asynchronous device.
921600/460800/230400/115200/57600/38400/28800/19200/14400/9600/7200/4
