Interface Introduction
- CH1~CH7: To output PWM signal (Additional, CH1 can output PPM signal). Can be connected to the servos, or other compatible components.
- BVD/VCC: During the battery voltage detecting process, a BVD harness is connected here. During normal operation, the power cable is plugged into this interface.
- BIND interface: During the binding process, a binding cable is connected to this interface.
- SENS interface: For connecting i-BUS sensors.
- SERVO interface: To output i-BUS or S.BUS signal.
Binding
The receiver supports two-way binding and one-way binding. The transmitter
will display the information returned from the receiver after the two-way
binding is completed.
Follow the steps below to bind in two-way binding:
- Select [2 WAY] for RF standard of the transmitter, then put the transmitter into bind mode.
- The receiver supports three ways to enter bind mode: BIND button binding, bind cable binding, and BIND button binding after power-on.
- BIND button binding: Press and hold the BIND button of the receiver while powering on the receiver, the LED of the receiver should be flashing, indicating that the receiver is in bind mode. Then release the BIND button.
- Bind cable binding: Insert the bind cable to the BIND interface of the receiver, then power on the receiver. The LED of the receiver should be flashing, indicating that the receiver is in bind mode. Note that you need to remove the binding cable from the receiver after the binding process is completed.
- BIND button binding after power-on: The receiver has not been connected to the transmitter when it is powered on. Press and hold the BIND button for 3 seconds, the LED of the receiver should be flashing, indicating that the receiver is in bind mode. Then release the BIND button.
- When the LED of the receiver is solid on, the binding process should be completed. The transmitter exits the bind mode automatically.
- Check to make sure the transmitter and receiver functions are working correctly, and repeat steps 1 to 3 (binding process) if any problems arise.
Follow the steps below to bind in one-way binding:
- Select [1 WAY] for RF standard of the transmitter, then put the transmitter into bind mode.
- Put the receiver into bind mode ( Refer to the description above for entering bind mode).
- When the LED of the receiver is in a slow flashing state, the binding process should be completed. You need to manually put the transmitter to exit the bind mode. Then the LED of the receiver is solid on, indicating that the binding is completed.
- Check to make sure the transmitter and receiver functions are working correctly, and repeat steps 1 to 3 (binding process) if any problems arise.
Note: Put the transmitter in bind mode first, then put the receiver in bind mode. If the binding is not completed within ten seconds, the LED of the receiver will enter its slow flashing state.
Firmware update
The firmware of this receiver is updated through the FlyskyAssistant (Only
version 3.0 or above is supported. The firmware of FlyskyAssistant is
available on the Flysky official website).
This receiver can be updated via the following two ways:
- After the binding between the transmitter and the receiver (the LED of the receiver is solid on), connect the transmitter to the computer, then open the FlyskyAssistant on the computer to update the firmware.
- Connect the transmitter to the computer. Then put the receiver to enter the forced update mode by referring to the following three ways (The LED of the receiver operates in a three-flash-one-off manner repeatedly). Afterward, open the FlyskyAssistant on the computer to update the firmware.
- Power on the receiver while pressing and holding the BIND button for more than ten seconds, until the LED of the receiver operates in a three-flash-one-off manner repeatedly, then release the BIND button.
- Power on the receiver first, then press and hold the BIND button for more than ten seconds, when the LED of the receiver operates in a three-flash-one-off manner repeatedly, then release the BIND button.
- Connect the bind cable to the signnal pins of the BIND and SENS, then power on the receiver.
Failsafe
The failsafe function is used to output the channel value according to the out-of-control protection value set by the user after the receiver loses its signal and is out of control to protect the model and personnel.It can also be set failsafe for each channel respectively. This receiver supports two failsafe modes: [ON]and [OFF]
- [OFF] It is no output for the interface of PWM.
- ON] Outputs the failsafe values set for each channel.
Notes:
-
For bus signal types such as PPM/i-BUS/S.BUS, a single or several of these channels are not allowed to be in [No output] mode.
The actual signal is held at the last output value when the channel is set to [No output] mode. -
Because the S.BUS signal information contains failsafe flag bits, the failsafe settings of each channel are communicated to subsequent devices by the failsafe flag bits. If the connected devices support the failsafe flag bit analysis, the failsafe values set for each channel are output after out of control.
-
For the signal PPM/i-BUS without failsafe flag bits, it supports the setting of the signal to [No output] mode in case of out of control. After setting to [No output] mode, regardless of the setting of the failsafe of each channel, each channel will be in [No output] mode after out of control.
Attention:
- Make sure the product is installed and calibrated correctly, failure to do so may result in serious injury.
- Please carefully check each power device and car frame instructions to ensure the power matching is reasonable before use. Avoid damaging the power system due to incorrect matching.
- Do not let the external temperature of the system exceed 90℃ /194 ℉, because high temperature will damage the power system.
- Make sure the receiver is mounted away from motors or any device that emits excessive electrical noise.
- Keep the antenna of the receiver at least 1cm away from conductive materials such as carbon or metal.
- Do not power on the receiver during the setup process to prevent loss of control.

waste, but have to be disposed of separately. The disposal at the communal
collecting point via private persons is for free. The owner of old appliances
is responsible to bring the appliances to these collecting points or to
similar collection points. With this little personal effort, you contribute to
recycling valuable raw materials and the treatment of toxic substances.
