    Redundant features

    The receiver is equipped with a redundant function for receiving SBUS from another receiver. The RX4R normally receives and processes a signal for its servo outputs and SBUS output. The advantage is that if we connect another SBUS receiver to SBUS In and the RX4R stops having a signal, it switches the signal processing to SBUS from another receiver. When the RX4R receives the signal again, it switches back to processing its own signal.
    The second receiver can be any SBUS receiver such as X8R, X6R, XSR, XM, XM +, RX8R and L9R, but it must be possible to switch off telemetry. The XM + receiver is particularly advantageous.

    Pairing

    Put the transmitter in pairing mode. Press and hold the F / S button, turn on the power, wait 2-4 s. Successful pairing is accompanied by a green LED and the red one flashes. Disconnect the power and release the button. If that doesn't work, try repeating the process, but increase the space between the transmitter and receiver to 1-2 m.

    PWM 1-4 / 9-12 output selection
    The receiver can change the range of output channels 1-8 (resp. 1- 4) at 9-16 (resp. 9-12). The change is made during pairing.
    For new operating systems such as OpenTX 2.2 (BindOPT option) or FrSky-OS, you can select the pairing mode during pairing, 1-8 s without telemetry and 9-16 without telemetry. This receiver is paired in the selected mode and no jumpers are needed.

    PWM frequency
    You can choose between 18 ms and 9 ms.

    • for PWM 18 ms - normally pair
    • for PWM 9 ms - connect only for the purpose of pairing the signal pins of channels 1 and 2 with a jumper and pair

    Channel extensions

    This receiver is 16-channel. However, to save space, only a few channels are up. All 16 channels are in the data bus called SBUS.
    There are the following options for getting more channels:

    • Pair two receivers to one transmitter module. This is only possible with two types of receivers, the X8R and X6R. One of the receivers must be paired with telemetry and the other not!
    • Use SBUS servos or connect the control unit via SBUS. Then the output channels can be remapped to 9-16 using mode 4.
    • Use converters from SBUS to CPPM or to PWM .

    <ு LED indication

    LED Meaning
    red flashes slowly is not a signal
    green on connected, paired, data transfer in progress
    green on, red flashing fast pairing
    green flashes twice failsafe save confirmation
    blue flashes three times Confirm varies on / off
    blue on mode 9 ms
    blue off mode 18 m
