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. 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 P5of7 c) Place the antenna of the transmitter in a vertical position. d) Turn on the transmitter and receiver. e) To enter Range Check Mode, press and hold the “F/S Range” button of the transmitter for 4 second, the RED LED of the transmitter module will be turned off, the effective distance will be decreased to 1/30. f) Walk away from the model while simultaneously operating the controls on the transmitter, confirm that all controls are completely and correctly operational at least 30 meters away. g) Press the “F/S Range” button for 1S-4S, the transmitter will exit Range Check Mode. 7 Safety range indicator The Two-Way Radio System has a feature to show the RSSI (Received Signal Strength Indication) of the receiver. When the RSSI is low, the Tx module would give out three types of alarm. Red: The receiver is very far from the Tx. Orange: The receiver is sound, but would be far from Tx. Yello: The receiver is sound, Green: The receiver is OK. Note: Due to many environment factors, there may be casual alarm. 8 Failsafe The receiver integrates the failsafe function for all channels. To set failsafe positions, press briefly(less then 1 second) the “F/S Range” button of the Receiver, the Tx module will make a long “beep” indicating the failsafe position is remembered by the receiver. 9 Alarm operation 9.1 Alarm states Tx module monitors the state of receiver and notify user by audible alarm. The alarm state is made a distinction between three levels: Red (Highest): constant three Beeps Orange (Medium): constant two Beeps Manual of Two-Way Radio System www.FrSky-rc.com P6of7 Yellow (General): one Beep Green: No Beep Alarm sourced from: -Rx interface 1: Analog Port 1 on Rx; -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. And the RSSI alarm setting is default by factory. 9.2 Pins Definition: The Pin definition on receiver and Tx module: It should be noted that the 3.3V voltage only have a limited driving current (1~10mA), should not be used for driving a MPU. RXD +5V GND AD2 × GND AD1 × GND RXD Input to Tx module TXD Output from Tx module +5V Not regulated voltage GND Ground RXD: input to receiver, RS232 level AD2: Voltage: max 3.3V AD1: Voltage: max 3.3V Pins Definition at Rx Pins Definition at Tx 10 LED Status: 10.1 LED status on Transmitter module: Red LED on and Green LED flashing: Working Mode. Red LED off and Green LED flashing: Range Check Mode. Red LED flashing: Binding Mode. 10.2 LED status on Receiver: Red LED on and Green LED glooming: Working Mode.
