BVD cable: When you need to use the BVD function to detect voltage, 󽗉rst weld the BVD cable
welding joint end (in the left 󽗉gure [15] ) to the receiver's BVD welding point (in the left 󽗉gure [9] ).
Then you can use the BVD function to detect voltage.
Notes:
1. When using the BVD function, connect the negative terminal of the detected battery to the
receiver's power cathode (in the left 󽗉gure [14]) .
2. BVD voltage detection range: 0 – 70 V.
Two sets of channel interface pins (corresponding to channels 5, 6, 7 and 8): When more than 4
channels or Newports need to be used, just weld the corresponding pins to the channel position
reserved in the receiver.
It should be noted that you use a new heat-shrinkable sleeve to cover the circuit board
to prevent from contacting with metal, so as to avoid a short circuit ！

对码 Binding
本款接收机采用上电自动进入对码的方式设计：
• 接收机上电即进入等待连接状态，等待与已对码的发射机建立通信；
• 若 2S 未与已对码的发射机建立通信，则自动进入对码状态，此状态持续 3S；
• 若与发射机对码成功，即进入正常通信状态；否则退出对码状态，回到等待连接状态。
注意：当本接收机与发射机完成对码使用时，发射机先开机，接收机再通电；关机时，接收机先断电，再关闭发射机。
若接收机先开机，此时若有同类发射机处于对码状态，可能会被错误对码，请小心避开！
接收机支持双向对码和单向对码（双向对码完成后发射机将显示接收机回传的信息），因此对码前需先在发射机端设置单向或双向对码。如需对码
接收机与发射机，对码步骤如下所述。
双向对码步骤：
1. 发射机选择双向通信后，使发射机进入对码状态；
2. 接收机上电；
3. 接收机 LED 灯常亮，即对码成功（发射机对码成功后自动退出对码状态）；
4. 检查发射机、接收机是否正常工作。如需重新对码，请重复以上步骤。
单向对码步骤：
1. 发射机选择单向通信后，使发射机进入对码状态；
2. 接收机上电；
3. 接收机 LED 灯变为慢闪后将发射机退出对码状态，此时接收机 LED 灯常亮，表示对码成功；
4. 检查发射机、接收机是否正常工作。如需重新对码，请重复以上步骤。
This receiver is designed to automatically enter the binding mode at power-on.
• The receiver enters the wait-for-connection state upon power-on, waiting for connection to be established with the bound
transmitter.
• If the receiver does not establish connection with the bound transmitter within 2S, it automatically enters the binding state.
This state lasts for 3S.
• If the binding with the transmitter is successful, it enters the normal connection state, otherwise, it exits the binding state and
returns to the wait-for-connection state.
Note: In case of binding, the receiver LED 󽗊ashes quickly. In case of wait-for-connection, the receiver LED 󽗊ashes slowly. In case of
normal connection, the receiver LED is solid on.
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 󽗉nished). 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.
Two-way binding steps
1. At the transmitter side, set Two way in Bind setting menu, then put the transmitter into bind mode.
2. Power on the receiver.
3. The receiver LED is always on after the binding is successful (The transmitter automatically exits the binding state after the
successful binding).
4. Verify that the transmitter and receiver are working properly. If you need to re-bind, repeat the above steps.
One-way binding steps
1. At the transmitter side, set One way in Bind setting menu, then put the transmitter into bind mode.
2. Power on the receiver
3. After the receiver LED becomes slow 󽗊ashing, then put the transmitter to exit the binding state. At this time, the receiver LED
is solid on indicating the binding is successful.
4. Verify that the transmitter and receiver are working properly. If you need to re-bind, repeat the above steps.
Notes:
1. The receiver's bind-wait state lasts only 3S. Ensure that the transmitter enters the binding state before the power-on of the
receiver.
2. The binding may fail in case of noisy radio environment or too long distance between transmitter and receiver.
3. If the AFHDS 3 protocol transmitter fails to bind with the Tr8B receiver, please check whether the RF library versions of both are
the same.
注：对码时，接收机 LED 灯快闪；等待连接时，接收机 LED 灯慢闪；正常通信时，接收机 LED 灯常亮。
注：
1. 接收机对码等待状态仅持续 3S, 请确保发射机先进入对码状态后，再给接收机上电；
2. 无线电环境嘈杂或发射机与接收机距离过远可能会导致对码失败；
3. 如果 AFHDS 3 协议发射机无法与 Tr8B 接收机对码，请检查两者高频库版本是否一致。
After the binding between the receiver and transmitter, the transmitter is powered on, and then the receiver is powered
on. In case of shutdown, the receiver is powered o󽗈, and then the transmitter is powered o󽗈. If the receiver is powered
on 󽗉rst, when there is a similar transmitter in the binding state at this time, there may be an incorrect binding.

固件更新 Firmware update
失控保护 Failsafe
失控保护功能用于在接收机与发射机失去信号不受控制后，接收机按设置好的失控保护值进行通道输出以保护模型及人员安全。
本款接收机共支持三种失控保护模式 : [ 无输出 ]、[ 保持 ] 和 [ 固定值 ]
[ 无输出 ] PWM 通道接口为无输出状态 ;
[ 保持 ] 输出失控前最后的通道值；
[ 有输出 ] 输出设置的固定值。
注：
1. 对于 PPM/i-BUS/S.BUS/i-BUS2 等总线信号类型不允许单个或其中几个通道为 [ 无输出 ] 模式，通道设置为 [ 无输出 ] 模式时，实际信号是保持
最后输出值；
2. 因 S.BUS/i-BUS2 信号信息包含失控标志位，各通道失控保护设置被失控标志位传达给后续设备，若连接的设备支持失控标志位解析，则失控后，
输出各通道设置的失控保护值；
3. 对于无失控标志位的信号 PPM/i-BUS，支持设置失控时信号 [ 无输出 ] 模式。设置为 [ 无输出 ] 模式后，不管各通道失控保护如何设置，失控后
各通道均为 [ 无输出 ] 模式。
注意事项：
• 使用前必须确保本产品与模型安装正确，否则可能导致模型发生严重损坏。
• 关闭时，请务必先关闭接收机电源，然后关闭发射机。如果关闭发射机电源时接收机仍然在工作，将会导致遥控设备失控。失控保护设置不合
理可能引起事故。
• 确保接收机安装在远离电机，电子调速器或电子噪声过多的区域。
• 接收机天线需远离导电材料，例如金属棒和碳物质。为了避免影响正常工作，请确保接收机天线和导电材料之间至少有 1 厘米以上的距离。
• 准备过程中，请勿连接接收机电源，避免造成不必要的损失。
本接收机固件更新需通过富斯遥控管家（FlySkyAssistant）完成（仅 3.0 及以上版本支持，富斯遥控管家固件可从官网 www.󽗊ysky-cn.com 获取）。
本接收机可以通过以下两种方式进入更新：
1. 先将发射机与接收机对码后（接收机 LED 灯常亮），再将发射机与电脑连接，然后在电脑端打开富斯遥控管家，通过富斯遥控管家进行固件更新；
2. 将发射机与电脑连接，参考如下方式使接收机进入强制更新状态（接收机 LED 灯状态三闪一灭），然后在电脑端打开富斯遥控管家，通过富斯
遥控管家进行固件更新。
进入强制更新状态的操作方式如下：
• 先将接收机 CH3 和 CH4 通道的信号端相连接，然后给接收机通电。
The 󽗉rmware of this receiver is updated through the FlyskyAssistant (Only version 3.0 or above is supported. The 󽗉rmware of
FlyskyAssistant is available on the Flysky o󽗋cial website).
This receiver can be updated via the following two ways:
1. 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 󽗉rmware.
2. 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-󽗊ash-one-o󽗈 manner repeatedly). Afterwards, open the FlyskyAssistant on the
computer to update the 󽗉rmware.
• Connect the signal pin of the CH3 to the signal pin of the CH4 󽗉rst, then power on the receiver.
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 No output for PWM interface.
Hold Keep the last output value.
Fixed value Output the failsafe values set for each channel.
Notes:
1. 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 󽗊ag bits, the failsafe settings of each channel are communicated
to subsequent devices by the failsafe 󽗊ag bits. If the connected devices support the failsafe 󽗊ag bit analysis, the failsafe values set
for each channel are output after out of control.
3. For the signal PPM/i-BUS without failsafe 󽗊ag 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.
Attentions:
• 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 o󽗈 the transmitter, failure to do so can result out of 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.
