Binding

The receiver supports the two-way binding and one-way binding (the transmitter will display the information returned from the receiver after the two-way binding is finished). Therefore, you need to set the one-way or two-way binding on the transmitter side before the binding. If you need to bind the receiver with the transmitter, the steps are as follows.

Follow the steps below to bind in two-way binding:

Select [2 WAY] for RF standard of the transmitter, then put the transmitter into binding mode.
The receiver supports two ways to enter binding mode: the BIND button 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 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 finished. The transmitter exits the binding mode automatically.
Check to make sure the transmitter and receiver functions are working correctly, repeat steps 1 to 4 (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 in binding mode.
Put the receiver into binding mode ( Refer to the description above for entering binding mode).

After the receiver LED becomes slow flashing, then put the transmitter to exit the binding state. At this time, the receiver LED is solid on indicating the binding is successful.
Check to make sure the transmitter and receiver functions are working correctly, repeat steps 1 to 4(the binding process) if any problems arise.

Functions Description

This 900M receiver supports 868MHz and 915MHz bands, and can be used with transmitters supporting FRM304 RF Module. The EMr receiver supports 4 Newport interfaces, and the output protocol type of the Newport interface can be set at the transmitter side. EX S.BUS or EX i-BUS2 can be set as the output protocol type of one Newport interface according to the actual receiver, and then connect this Newport interface with any receiver that supports i-BUS2 or S.BUS signal output, and then the signal redundancy function can be worked through the setting to improve the communication quality.

Note: Only one Newport interface’s output protocol type can be set to EX.S.BUS or EX i-BUS2.

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 firmware update can be finished in two ways:

Mode Ⅰ: 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.

Mode Ⅱ: Connect the transmitter to the computer. Then put the receiver to enter the forced update mode by referring to the following way (The LED of the receiver operates in three-flash-one-off mode repeatedly). Afterwards, open the FlyskyAssistant on the computer to update the firmware.
- Power on the receiver while pressing the BIND button for more than 10 seconds, until the LED works in three -flash-one-off mode repeatly, then release the BIND button.
- Power on the receiver first, then press and hold the BIND button for more than 10 seconds, the LED works in three -flash-one-off mode repeatly, then release the BIND button.

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.
This receiver supports three failsafe modes: No output, Hold, and Fixed value.
No output for PWM interface.

Hold Keeps the last output value.
Fixed value Outputs the failsafe values set for each channel.

Notes:

For bus signal types such as PPM/i-BUS/S.BUS/i-BUS2, 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/i-BUS2 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.
Make sure the receiver’s battery is disconnected before turning off the transmitter, failure to do so lead to lose control. Unreasonable setting of the Failsafe may cause accidents.

Make sure the receiver is mounted away from motors, electronic speed controllers or any device that emits excessive electrical noise.
Keep the receiver’s antenna 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.
