FGr4D Four Channel Two Way Receiver Based
Instruction Manual

Introduction

The FGr4D is a four-channel two-way receiver based on AFHDS 3 (ThirdGeneration Automatic Frequency Hopping Digital System) protocol.
This receiver features dual antennas, PPX6 nano waterproof, compact and lightweight design. It supports 4 Newport function interfaces (Newport can be customized with input or output signal types: i-BUS2/S.BUS/i-BUS/PPM). The FGr4D can be used as a PWM converter, adaptable to a model car or model boat..、

Installation

The receiver has two built-in antennas. In order to ensure the signal quality and avoid the remote control distance affected, the receiver antenna should be perpendicular to the model body (as shown in the figure) when installing the receiver!

Binding

The receiver supports two -way binding and one-way binding, and can be set at the transmitter side. 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 Two WAY for RF standard of the transmitter, then put the transmitter in bind mode.
The receiver supports two ways to enter bind mode: 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, tthe 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 bind mode automaticlly.
Check to make sure the transmitter and receiver functions are working correctly, repeat steps 1 to 3 (binding process) if any problems arise.

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

Select One WAY for RF standard of the transmitter, then put the transmitter in bind mode.
Put the receiver in bind mode ( Refer to the description above for entering bind 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 3 (binding process) if any problems arise.

Note: When this receiver is used as a PWM converter, it is necessary to finish configurations at the transmitter side. In this case, if the LED works in Flash-once, ON-once, and OFF-once state, it indicates that no i-BUS2 signal is received; if i-BUS2 signal is received, the LED works in Flash-once and ON- once state.

Firmware Update

The firmware of this receiver can be updated via the FlyskyAssistant (Only version 3.0 or later is supported. The firmware of FlyskyAssistant is available on the Flysky official website: www.flysky-cn.com).
This receiver can be updated through 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 two ways (The LED of the receiver works in three-flash-one-off mode repeatedly). Afterwards, 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 works in three-flash-one-off mode 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 works in three-flash-one-off mode repeatedly, 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.
It can also be set failsafe for each channel respectively. This receiver supports three failsafe modes: No output, Hold, and Fixed value.
No output It is no output for the interface of PWM.
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.
2. 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.
3. 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.
