Product Description

FrSky D4R-II 4ch 2.4Ghz ACCST Receiver (w/telemetry & RSSI output and CPPM - PPM SUM) on sale save USD10 - so The D4R-II's data port allows you to connect a sensor hub , then connect GPS, Variometer, temperature, RPM and all of the other great FrSky sensors. It also has 2 full length antennas.  There is also a hack which allows you to connect a D4R-II direct to a FVAS-02 without a hub.  The D4R-II from FrSky is a favourite Rx for C-PPM enabled mini Quad controllers like our Aussie PARIS v2 Hero. and HERO•32 bit naze because it is compact, has 1 wire 8 channels ; and can easily be connected to the voltage sensor FBVS-01 and the Variometer SPort with our D4R-II hack below (without any HUB needed!)

Compatibility
Compatible with FrSky two-way telemetry modules: DFT, DJT, DHT, DHT-U and Taranis in D8 mode


Features

  • RSSI (PWM) and  PPM SUM output.  NOTE : If Ch3->Ch4 is jumpered closed ; then Ch1 = C-PPM and Ch2 = Rssi(PWM)
  • A2 voltage input from FBVS-01 or mini-andromeda (Please note that the pin sequence is different between D4Rii and X4RSb - even though they look the same - A2 pin is in a different position
  • Lighter weight and physically smaller than D8R-II & D6FR
  • Integrated warning alarm for low voltage, poor reception, etc.
  • D4R-II side Port - GND/A2/Tx/Rx - analog telemetry A2 port and one digital data-stream Tx/Rx port (Connects to FrSky Sensor Hub FSH-01).


Specs of D4R-II
Number of Channels: 4 (8 by C-PPM)
Operating Voltage Range: 3.5V~10V
Operating Current: 60mA
Operating Range: Full Range (>1.5km)
Dimension: 40x22.5x6mm
Weight: 5.8g

There is a firmware update available here to change the CPPM spacing from 18ms to 27ms - For all PARIS ops using CPPM we recommend to set your servo travel (if used) to be 1100-1900 (not 1050-2000)

 

 D4R-II Bind procedure 

  1. Ascertain that the transmitter is in the PPM mode. Turn the transmitter off. 
  2. Turn on the transmitter while holding the F/S button on the transmitter module (Ensure that both switches on the transmitter module are OFF when using this receiver in the two way mode). Release the button. The RED LED on the transmitter module will flash, indicating the transmitter is ready to bind to the receiver. 
  3. 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. Turn off both the transmitter and receiver. 
  4. Turn on the transmitter and connect the battery to the receiver. The GREEN LED on the receiver will indicate the receiver is receiving commands from the transmitter. 

The receiver/transmitter module binding will not have to be repeated, unless one of the two is replaced. 

 

D4R-II Range check
A pre-flight range check should be done before each flying session. Reflections from carbon, 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:

  1. Place the model at least 60cm (two feet) above non-metal contaminated ground (e.g. on a wooden bench).
  2. The receiver antennas should be separated by 90° in the model, and not touching the ground plane (carbon).
  3. Place the antenna of the transmitter in a vertical position.  the Tx antenna radiates power from the side - do NOT point a Tx antenna at the model.
  4. 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, and the BEEPER will sound. The effective distance will be decreased to 1/30 of full range.
  5. Walk away from the model while simultaneously operating the controls on the transmitter, confirming that all controls operate normally.
  6. Press the F/S button for 1S-4S to exit range check mode, RED LED will be back on, indicating normal operation is back.

  1. Excellent Receiver

    Just because it's small don't think you loose any distance. It's small, light and best of all it sends telemetry back to the tx so you know your RSSI strength at all times. Can also do Voltage and Current with the smart port upgrades
