1. Disclaimer

Thank you for purchasing the T21 hand-held remote-control station. Please use it in

accordance with local radio control regulations and read this statement carefully before

using it. Once used, it shall be deemed to endorse and accept all contents of this statement.

Please strictly follow this instruction to install and use the product. The supplier will not

bear any legal liability for any result or loss caused by improper use, installation, final

assembly or modification of the product.

2. Product Precautions

1) T21 ground unit is matched with airborne unit R20 to use together.

2) The ground unit is with built-in 12v battery (3S lithium battery). The airborne end

needs external power input DC7.4-12V(2S-3S lithium battery). Please power the system in

strict accordance with specifications.

3) With improper operation, the aircraft may cause a certain degree of injury and damage

to human and the system, please be sure to pay attention to safety during use.

4) In order to better serve customers, our R&D team has been upgrading and optimizing

the product. The software and firmware will be upgraded frequently. There may be

incompatibilities between different firmware versions. Please pay attention to asking the

supplier for the latest software firmware and technical support.

5) Software and firmware version example: calling software: HZY_ToolBench V1.2.3.4;

Ground end firmware: TTX 30-1.2.3-1.0; airborne end R20 firmware: RSx16-1.2.3-1.0;

airborne end V20 firmware: V20RX-1.2.3-1.00.

6) The software, firmware, drivers, port conversion tools, etc. involved in this manual will

be updated from time to time on our website, please visit our website to download, or

7) If you encounter any problem that cannot be solved during installation or use of the

product, please contact us or visit our web www.chinowing.com

2.1 Installation Note

1) Be sure to use the spare parts provided by our company.

2) Be sure to install the antennas before power on to avoid damage to the circuit.

www.chinowing.com

3) Try to make the receiver antenna without obstruction, and the end part of the antenna is

vertically downward without bending, so as to avoid shortening the communication

distance or even failing to communicate due to obstruction.

4) Do not disassemble or refit without permission. If you encounter any problem that

cannot be solved during installation, please contact us directly.

5) During installation, keep proper distance between electronic devices to minimize

electromagnetic interference.

2.2 Precautions for Use

1) Before use, please make sure that all connection wires are fastened reliably and all parts

work normally.

2) Please open the configuration software of the remote control and check whether the

channels are normal.

3) Please check the surrounding environment to ensure that there is no interference from

other devices, otherwise T21 data transmission performance will be seriously affected.

4) Check the power of the remote control before use. If the parameter adjustment software

shows that power is low, please charge the remote control timely. If the remote control is

turned off, the receiver has entered the state of Fail-safe protection. Stop using it when the

battery is too low. Don't rely on the device's low-power alarm, which is only a precaution

and tells you when to charge. It takes about 5hs to be fully charged.

3. Product Introduction

T21 is a highly integrated system of remote controller, data link and ground control station.

With the compact size, easy operation, T21 has 16 adjustable Channels and dual SBUS

output, able to control the dorne and the payload simultaneously. Working under the

frequency of 840MHz/900MHz, it can transmit stable data at the max range of 30km. It has

been widely used in UAV, UGV, USV, etc.

5. Product Instruction

5.1. Airborne unit(receiver) R20

①Power supply interface: pls use XT30 plug to power, power supply: 7.4-12v

②COM port: TTL, used for connecting COM port or API prot of flight controller

③S-BUS1 interface: to connect flight controller or other devices

④S-BUS2interface: to connect flight controller or other devices

⑤Signal strength indicator: S3 ON, signal is weak; S3 and S2 ON, signal is moderate; S3, S2

and S1 ON, signal is strong.

⑥Data transmission indicator: RXD indictor ON means there is data receiving of the receiver;

TXD indictor ON means there is data transmitting of the receiver.

⑦S-BUS data indicator L1: used for indicating the communication status of remote

controller and receiver

⑧Receiver configuration mode indicator L2: used for indicating whether it is in the

confinguration mode

⑨SET button: frequency modulation button between remote controller and receiver

By default, the S-BUS1 and S-BUS2 interfaces output the CH1 to CH16 of the

remote control to 1-16 channels.

5.3. Receiver R20 Installation and Connection

1. Connecting antennas to SMA port of Rx.

2. Fix the receiver to the appropriate position of the aircraft by using double-sided tape.

3. As shown in the above photo, connecting COM port and S-Bus port of the R20 receiver to

your device by lead wire of servo.

Receiver GND

GND Flight controller, etc

Receiver +

+ Flight controller,

etc

4. With 7.4-12v DC power input, L1 indicator will flicker. That means the success

connection of transmitter and remote control.

5. If you are using a dual S-Bus receiver, both S-Bus1 and S-Bus2 output CH1 to CH16 from

the remote control. And the output of S-Bus1 and S-Bus 2 can be mapped separately. See

the output mapping description.

The default power of the receiver: 1W. Please keep the antenna away from other

electronic devices (GPS, compass, etc.) to avoid interference.

Be sure to install the antenna before power on, otherwise it may burn out the radio

module.

When using, try to make the antenna face down and without any obstacle to block,

so as to avoid the communication distance being shortened due to blocking, or even unable to

communicate.

Be sure to use the specified type of antenna and install it correctly. Do not use other

types of antennas.

6. Remote Controller Operation

6.1. Power on and Power off of the Tablet

1. Long press the power button. Release it when you see the power-up screen.

2. After the computer is turned on, you can check the remaining battery power through

indicator icon in the lower right corner of the desktop. If less than 20% power, please

charge timely.

3. After finishing the operation, pls power off the computer through the computer shutdown

interface.

When you do not use your computer for a long time, please turn it off in time to avoid

the power consumption.

If it is found that the long press the power button cannot start up the system, it is

likely that the battery is with low capacity. Please charge it by standard adapter.

6.2. Power On and Power Off of the Remote Controller

Power on: long press for 5s

Power off: long press for 5s
