2.4GHz Two-Way Radio System
1.
Introduction
The Two-way Radio System developed by FrSky provides an additional return link
that would be used for monitoring the Rx's voltage, temperature, location, speed and so
on.
2.
Overview
2.1
Transmitter modules:
a)
Model: DFT
Compatible with the following transmitters:
Futaba: 3PM, 3PK, 7U, 8U, 8J, 9C, 9Z, 10C, FN series, T10C, FC-18, FC-28.
Hitec: Optic 6, Eclipse 7, Prism 7.
WFLY: WFT09, WFT08.
b)
Model: DJT
Compatible with the following transmitters:
JR: 347/388/783/U8/PCM10/PCM10S/PCM10SX/PCM10IIS/8103/J9303/PX/9XII.
2.2
Receiver module:
a)
Model: D8R, D8RHV
Compatible with FrSky Two Way module DFT/DJT.
b)
Model: V8R, V8RHV, V8R7, V8R7HV, V8R4
V8 receivers work with DFT/DJT, just in receive-only mode.

Page 3: How To Use
6.1.1 Installation of the transmitting module: a) Remove the original transmitting module. b) Put the FrSky 2.4GHz transmitter module into the module port of your RC transmitter and screw on the transmitting antenna. Check the MODE switch to its corresponding position. - Page 4 Manual of Two-Way Radio System www.FrSky-rc.com P4of9 6.1.2 Installation of receivers: The D8R receiver incorporates two separate antennas which enable them to receive the radio signal at two different locations. Please make sure that the two antennas are placed apart and oriented 90 degrees to each other.
- Page 5 Manual of Two-Way Radio System www.FrSky-rc.com P5of9 For safe operation, it is necessary to perform pre-flight range check. Caution must be paid when you perform check in an environment with metal fences, concrete buildings, or rows of trees. Loss of signal may be experienced.

Page 6: Alarm Operation
Receiver, the Tx module will make a long “beep” indicating the failsafe position is remembered by the receiver. version: Provided for users to upgrade FrSky two way transmitter modules’ ROM B failsafe version. In this case, you can set failsafe position on the Tx module at any time during your flight. - Page 7 Manual of Two-Way Radio System www.FrSky-rc.com P7of9 -Rx interface 2: Analog Port 2 on Rx; -Rx interface 3: RSSI of Rx; Note: The alarm threshold of Rx interface 1 and 2 could be set by user. Two alarm thresholds and three levels alarm state are available for both of Rx interface 1 and 2.
- Page 8 Red LED flashing and Green LED on: Binding OK. 11. Firmware Upgrade Frsky have developed a mechanism of firmware upgrade. With it, user would like to upgrade to new version of software when available. And the Two-Way Radios System is supported by this mechanism.
- Page 9 France: except the channel 10 through 13, law prohibits the use of other channels. For more information, please kindly refer to the Two Way Protocol. Should you have further queries, pls feel free to contact FrSky technical support by e-mail: sales4tech@gmail.com.
