The Two-way Radio System developed by FrSky provides an additional return link that would be used for monitoring the RxΆs voltage, temperature, location, speed and so on.

2.     Model: DJT
Compatible with the following transmitters:
JR: 347/388/783/U8/PCM10/PCM10S/PCM10SX/
PCM10IIS/8103/J9303/MX-22/MX-24S/PX/9XII.


3. Features
a) Advanced Continuous Channel Shifting Technology (ACCST SYSTEM) achieves high reliable link in interference rich environments.
b) Easy to bind and instant link-up.
c) Excellent reboot times.
d) All channels failsafe.
e) Quick response.
f) Very smooth servo movement.
g) Alarm on events of receiver (low battery voltages, poor reception, etc.)
h) Error-free link, by using 48bits CRC algorithm.
i) Low power consumption.
j) True two-antenna diversity.
k) Firmware upgradable.

4. Function of Two Way communication
a) Two way communication between receiver and transmitter
b) Receiver is able to accept 2 analog inputs, which can be used to monitor battery voltage, temperature sensor, etc., and transfer them to transmitter. Users can set the Alarm Level of these analog voltages, when exceed or below these levers, sound alarm is issued.
c) Receiver is able to accept serial data streams from simple 3-wire RS232 port, such information as GPS, altitude, and user developed data can be transferred to Tx without error, and sent at the RS232 port on the Tx.


5.2 Transmitter module specifications:
Model:  DJT
Operating Voltage Range: 6.0V-13.0V
Operating Current: 50mA
Output Power: 60mW
Resolution: 11bit (3072)

1. Instruction Manual for D8R (V2) Receiver

1.1 Compatibility:

Compatible with FrSky two way telemetry modules: DFT, DJT, DHT, DHT-U

1.2 Specification:

Dimension: 54*27*17mm

Weight: 16.2g

Operating Voltage Range: 3.5V-10.0V

Operating Current: 100mA

Specified Range: 1.5km

Resolution: 3072 (>11bit)

Frame Rate: 18ms (FS)

             9ms (HS)

1.3 Superiority over D8R:

1) Built-in battery voltage sensor in A1;

2) Two switchable PPM modes: FS mode and HS mode;

3) No need to open the receiverΆs case when upgrading.

2. Setup

2.1 Bind procedure:

a) Turn your transmitter on and switch it to PPM mode. Turn your transmitter off.

b) Turn your transmitter on while holding the F/S button on the transmitter module (Please make sure that both switches on the transmitter module are OFF in two way mode). Release it in a few seconds. The RED LED on the transmitter module will flash, indicating the transmitter is ready to bind the receiver.

c) Connect battery to the receiver while holding the F/S button on the receiver. The LED on the receiver will flash, indicating the binding process is completed.

d) Turn on the transmitter and connect battery to the receiver. The Green LED on the receiver will indicate the receiver is receiving commands from the transmitter.

Notice: Please make sure that the battery is plugged into CH1~CH8, rather than side port (A2 or Rx), otherwise you will notice no function of the servos.

2.2 Range check:

It is highly suggested to perform pre-flight range check. Caution must be paid when you perform range check in environment with metal fences, concrete buildings, or rows of trees. Loss of signal may be experienced.

Please kindly follow the steps below to perform range check: (Note: this would be done with the receiver installed in the model):

a) Place the model at least two feet (60cm) above non-metal contaminated ground (like wooden bench).

b) Place the receiverΆs antennas apart. Do not let the antennas touch the ground.

c) Place the antenna of the transmitter in a vertical position.

d) Turn on the transmitter and receiver, press the F/S button of the transmitter for 4 seconds to enter range check mode, the RED LED of the transmitter module will be off, the effective distance will be decreased to 1/30.

e) Walk away from the model while simultaneously operating the controls on the transmitter, confirming that all controls are completely and correctly operational at least 30 meters away.

f) Press the F/S button for 1S-4S, the transmitter will exit range check mode.

2.3 Setting failsafe:

D8R supports failsafe function for all channels. Please kindly follow the steps below to set failsafe:

1) Bind the receiver first;

2) Set failsafe at any required position on any channel;

3) Press briefly the F/S button of the receiver (less than 1 second), the transmitter module will make a long “beep”, indicating the failsafe position is remembered by the receiver.

If you do not need the failsafe function any more, just re-bind the receiver to set default failsafe mode.

2.4 LED status:

RED LED    GREEN LED    Mode
On    Glooming    Working Mode
Flash    Off    No Signal
Flash    On    Binding OK

2.5 Pins definition:

It should be noted that 3.3V voltage only has a limited driving current (1~10mA), should not be used for driving a MPU.

RXD    +5V    GND
AD2    ×    GND

RXD: input to receiver, RS232 level

AD2: Voltage: max 3.3V

AD1: built-in battery voltage sensor

3. How to switch between two PPM modes

Turn the transmitter off, connect the battery to the receiver, press the F/S button of receiver for 6 seconds and then release. The red LED will flash fast in HS Mode and slow in FS Mode.

Warning: HS Mode is only applied for high-speed digital servos. Other servos should select FS Mode, otherwise servos will get heat or even burn out.
