Overviews 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/MX-22/MX-24S/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. 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. Manual of Two-Way Radio System www.FrSky-rc.com P2of7 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 Point of these analog voltages, when exceed or below these points, sound alarm is presented. 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 presented at the RS232 port on the Tx. 5. Specifications 5.1 Receiver specifications: Model: D8R Weight: 16.2g Dimension: 54*27*17mm Operating Voltage Range: 4.0V-7.2V Operating Current: 100mA Specified Range: 1.5km (Ground Range) Resolution: 11bit (3072) Latency: 22ms Number of Channels: 8CH Analog voltage: 0~3.3V 5.2 Transmitter module specifications: Model: DFT, DJT PDF 文件使用 "pdfFactory Pro" 试用版本创建 www.fineprint.cn Manual of Two-Way Radio System www.FrSky-rc.com P3of7 Operating Voltage Range: 6.0V-13.0V Operating Current: 50mA Output Power: 60mW Resolution: 11bit (3072) Important! The effective range of control refers to the distance between the transmitter and the receiver clear of obstruction. All data was tested and verified by FrSky. However this is not guaranteed due to many factors such as the flying environment and the weather, which can greatly affect the effective range of control. It is extremely important to range check your models prior to each flying session! 6. How To Use 6.1 Setup 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. c) Check the MODE switch to its corresponding position. Mode Switch 1 Switch 2 Mode 1 OFF OFF Two-way Mode 2 OFF ON V8 Mode 3 ON OFF Not Defined 4 ON ON Firmware Upgrade d) Turn the transmitter power on and check the LED status on the module. 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 be apart placed and 90 degrees crossed. Please note: As the wave length of 2.4GHz is shorter than older RC systems, its ability Manual of Two-Way Radio System www.FrSky-rc.com P4of7 to go around solid obstacles is weaker than 72 or 36 MHz. So the antennas must avoid objects with high conductivity, such as metal parts, servos, ESC’s, battery packs, wires, and carbon fiber structures. If possible put the tip of the antennas outside of the fuselage for maximum reception. 6.1.3 Receiver and Transmitter Setup Instructions: Follow the steps below to properly set up your system. a) Turn your FUTABA or JR transmitter on and switch it to PPM mode, power off the TX. b) Check the working mode of the Tx module. c) Turn the transmitter on while holding the programming button. Release it a few seconds later. The RED LED on the transmitter module will flash indicating the transmitter is ready to bind the receivers. d) Connect the battery to the receiver while holding the receiver’s button. The LED on the receiver will flash indicating the binding process is complete. Turn off the receiver. e) Turn off the transmitter and receiver to finish the binding procedure. f) Turn on the transmitter. g) Connect the battery to the receiver, the Green LED on the receiver will indicate the receiver is receiving commands from the transmitter. After the steps above are completed, both the transmitter and receiver are ready to be used. 6.2 Range check For safe operation, it is necessary to perform pre-flight range check. Caution must be paid when the units in the environment of metal fences, concrete buildings, or rows of trees. Loss of signal may be experienced. Perform a range check as follows (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; for example a wooden bench. b) Place the receiver’s antenna apart. Do NOT let the antenna touch the ground.
