1. Introduction
1.1 Compatibility
Compatible with FrSky two way telemetry modules: DFT, DJT, DHT, DHT-U
1.2 Specifications
Dimension: 55*25*14mm
Weight: 12.4g
Operating Voltage Range: 3.5V-10.0V
Operating Current: 100mA
Operating Range: full range (>1.5km)
Servo Frame Rate: 18ms (FS – Normal Speed Mode)
9ms (HS – High Speed Mode)
1.3 Features
1) Two external analog telemetry ports (A1&A2) and one digital data-stream port (Rx);
2) When side port pins of A1 and X are connected by the jumper, A1 will change from external analog telemetry
port to internal built-in battery voltage sensor;
3) Convenient to upgrade – no need to open the receiver’s case when upgrade D8R-II plus;
4) Two switchable PPM modes - FS mode and HS mode;
5) Alarm warning on low voltage, poor reception, etc.
2. Set
up
2.1 Bind procedure
1) Ascertain that the transmitter is in the PPM mode. Turn off the transmitter.
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 D8R-II plus in 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 RED LED on the receiver will
flash, indicating the binding process is completed. Turn off both the transmitter and the receiver.
4) Turn on the transmitter and connect the battery to the receiver. The RED 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.
Warning: Battery or servos are NOT to be plugged into side ports (A1/A2/Rx), otherwise damage may occur.
2.2 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 range check and during the flight.
The following steps are to be followed to perform the range check of the model before the 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 in the model, and do not touch the ground.
3) Place the antenna of the transmitter in a vertical position.
4) Turn on the transmitter and the receiver, press the F/S button of the transmitter module 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.
