FrSky 2,4GHz Tee-Se-Itse telemetria moduuli. Nopea ja luotettava ACCST teknologia (FHSS). Sopii kaikille radioille (joissa PPM lähetys), mutta pitää itse asentaa radion sisälle. Kolme johtoa pitää juottaa radioon (+, - ja PPM signaali). PPM signaali johdon löydät seuraamalla johtoa, joka menee lähettimessäsi lähetinmoduliin (jossa antenni kiinni). Uusi malli, jossa PPM linjan suojaus. Yhteensopiva kaikkien FrSky telemetria antureiden ja normi ja telemetria vastaanottimien kanssa. Liitin johon voit liittää LCD näytön. 1.1 Compatibility: Switch 1 Switch 2 Mode of DHT Compatibility OFF OFF Two-way Mode Two way telemetry receivers (D8R, D6FRãD4FR) OFF ON V8 Mode V8 receivers (V8FR-HV, V8R7-HV, V8R7-SP, V8R4) 1.2 Specifications: Dimension: 55mm*34mm*8mm (2.17”L x 1.34”W x 0.32”T) Operating Voltage Range: 6.0V-13.0V Operating Current: 50mA Output Power: 60mW Resolution: 3072 (>11bit) 2. Setup 2.1 Installation process: 1ï¼Open the transmitter and find a clear position to locate the DHT module, the antenna connector and the small electronic panel. The location of the antenna should be such that there is no metal touching the antenna after it is mounted. 2ï¼ Locate the battery power supply line, GND and PPM signal line. These are often a three-wire bundle or ribbon cable connected to a separate transmitter circuit card. Use a voltmeter and/or oscilloscope to help identify the function of each wire. (RED→V+; BLACK→GND; YELLOW→PPM) 3ï¼Cut one hole in the transmitter and mount the PCB with F/S button, GREEN/RED LED and two switches. 4ï¼Drill a hole at the desired location in the transmitter case to mount the antenna connector. 5ï¼Attach the transmitter antenna to the RF connector. Turn the transmitter power on and check the power indicator LED on the new DHT control panel. It is normally light RED. 2.Bind procedure 1ï¼Ascertain that the transmitter is in the PPM mode. Turn the transmitter off. 2ï¼Set the two switches on the DHT panel to work with the receiver you are using. See the table above. 3ï¼Turn your transmitter on while holding the F/S button on the transmitter module. Release it in a few seconds. The RED LED on the transmitter module will flash, indicating the transmitter is ready to bind to the receiver. 4ï¼Connect the battery to the receiver while holding the F/S button on the receiver. The RED LED on the receiver will flash, indicating the binding process is completed. Turn off both the transmitter and receiver. 5ï¼Turn on the transmitter and re-connect the battery to the receiver. The RED SOLID LED on the receiver will indicate the receiver is receiving commands from the transmitter. The receiver/transmitter binding will not have to be repeated unless one of the two is replaced. After the above steps are completed, both the transmitter and the receiver are ready to be used. Warning: When working with two way telemetry receivers (D8R or D6FR), make sure that the battery and servos are plugged into CH1~CH8/CH1~CH6 rather than side port (A2/Rx), otherwise damage may occur. 2.3 Range check A pre-flight range check should be done before each flying session. Reflections from nearby metal fences, concrete buildings, or trees can cause loss of signal both during the range check and during flight. The following steps are to be followed to perform the range check of the model before flight: Place the model at least 60cm (two feet) above non-metal contaminated ground (e.g. on a wooden bench). 1) The receiver antennas should be separated in the model, as described in the receiver manual, and not touching the ground. 2) Place the antenna of the transmitter in a vertical position. 3) 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, GREEN LED will flash rapidly, the BEEPER will sound. The effective distance will be decreased to 1/30 of full range. 4) Walk away from the model while simultaneously operating the controls on the transmitter, confirming that all controls operate normally to a distance of at least 30 meters (~30 yds). 5) Press the F/S button for 1S-4S to exit range check mode, the RED LED will be back on, indicating normal operation is activated. 2.4 Signal loss indicator and failsafe setting In some special circumstances, such as strong interference, the signal may be lost. When signal is lost in a short period, the receiver continues to try to search for the transmitter, at the same time it keeps the last command from the transmitter, until a new command is received. Failsafe is a useful feature in which all controls move to a preset position whenever the control signal is lost for a period of time. FrSky receivers support failsafe function for all channels. Follow the steps below to set failsafe: 1) Bind the receiver first and turn on both transmitter and receiver; 2) Move all controls to that desired as the failsafe position; 3) Press briefly the F/S button of the receiver (less than 1 second), the transmitter module will make a long “beep” (for D8R only) or the GREEN LED of the receiver will flash twice, indicating the failsafe position has been set in the receiver. To disable the failsafe function, re-bind the receiver.
