The D8R-II Plus is a slight change from the older D8R-II. It allows the user to select an internal or external voltage sensor. The D8R-II did not have an internal voltage sensor. The internal voltage sensor is a nice feature for our glider and gas pilots, and the external sensor is great for our electric pilots.
Compatible with FrSky Taranis and the telemetry modules: DFT, DJT, DHT, DHT-U
Operating Voltage Range: 3.5V-10.0V
Operating Current: 100mA
Operating Range: 1.5km
Resolution: 3072 (>11bit)
Servo Frame Rate: 18ms (FS – Normal Speed Mode)
9ms (HS – High Speed Mode)
Two external analog telemetry ports (A1&A2) and one digital data-stream port (Rx);
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;
Convenient to upgrade – no need to open the receiver’s case when upgrading;
Two switchable PPM modes - FS mode and HS mode;
Alarm warning on low voltage, poor reception, etc.
Warning: Battery or servos are NOT to be plugged into side ports (A1/A2/Rx), otherwise damage may occur.
Warning: HS mode is only applied for high-speed digital servos. Other servos should select FS mode, otherwise servos will get hot and may burn out.
