失控保护
首先非常感谢您，使用本产品。请严格按照手册使用本产品。我们
不承担使用本产品或非法改装、操作不当产生的任何责任，包括但不限
于间接损失或连带责任，最高赔偿不高于产品本身价格。一旦使用即代

RX1 & RX2 端口设计有过载保护机构，允许接收机连接传感器，但
不建议连接大功率设备，如：舵机，灯光系统等。
连线示意图
S.HUB duo 采 用 单 电 源 输 入，电 源 可 以 是 2S Lipo（推 荐），2S
LiFe 等。产品本体不再提供电压指示功能，电源直接输出（不稳压），用
户可以通过回传功能监控接收机电压，也可以配合双天 RXB 接收机专用
锂电池使用，其集成的 IVM 电压显示器方便随时随地了解电池电量。
产品提供安全开关（Fail safe switch) 功能，可以连接 FSS-4（标配，
#46814）、FSS-3（#46813）甚至遥控开关。注意：与电池连接后，即
便是关机状态也有毫安级耗电，如果当日不再使用，请断开电池连接。
输入电源及开关
S.HUB duo 可输出最多 18 个 PWM 通道，当使用的制式少于 18 通
道时，多余通道没有输出信号。舵机输出端口的频率与输入总线频率自
动同步。
举例：当接收机工作在 S.Bus 16/18CH 模式时，输出端口频率为
15ms。当接收机工作在 S.Bus 12CH 高速模式时，输出端口频率同步提
高到 6ms（此模式下只能使用数字舵机），第 13 至 18 舵机端口无输出。
单个舵机输出口的最大连续电流为 2.5A，最大 5A，过大的电流会损坏
端口插针。
舵机输出端口
无论接入接收机是上述哪种协议，S.HUB duo 解码 PWM 舵机信号
的同时，再次将其编码成 S.Bus 信号，并通过 SBUS 端口输出。以便接
驳更多的 S.Bus 兼容设备，例如：S.HUB mini（#21898）或陀螺仪等。
端口允许最大 5A 工作电流。
除了获得优质的 S.Bus 总线数据（双接收机模式）之外，当 RX 协议
为 EX.Bus 24CH, 系统会将 9CH-24CH 的数据编码到中继 18CH S.Bus
总线中。这样一来，配合使用 S.HUB mini，就可以充分利用 24 个通道
的功能，特别是第 19 至第 24 通道。
S.Bus 信号中继
S.HUB duo 的失控保护策列为“保持”(Hold)，舵机保持失控前最
后的位置。只有当 RX1 和（或）RX2 的物理连接线全部故障时，才会激
活 S.HUB duo 的失控保护，否则，会执行主接收机的失控保护。

S.HUB duo 支持三种总线协议（S.Bus, EX.Bus, SRXL)，初始化时
优先连接上次使用协议（快速启动功能），如果连接不上，自动切换协议
并尝试。
S.HUB duo 支持双接收机冗余。当连接两个接收机时，RX1 为主接
收机。当然，也支持单接收机模式，连接 RX1 或 RX2 都可以。RX1 和
RX2 端口旁有 LED 指示灯，连同主 LED，指示并记录飞行过程中的信号

S.HUB
The RX1 & RX2 port is designed with overload protection. It allows the receiver to
connect with sensors, but it is not recommended to connect high-power equipment such
as servos, lighting systems, etc.
Wiring Diagram
S.HUB duo use single power input. The power source can be 2S Lipo (recommended),
2S LiFe, etc. The product no longer provides the voltage indication function. The power
supply output directly (unregulated). So that user can inspect the receiver voltage
through the telemetry function. S.HUB duo also work well with the Dualsky RXB receiver
Lipo battery. Which is integrated with IVM voltage monitor. Pilot can check the capacity
easily at any time.
The product provides a failsafe switch function, which can be connected to FSS-4
(standard, # 46814), FSS-3 (# 46813) and even remote switches. Note: After connecting
to the battery, even it is turned off, there is a milliamp-level power consumption. If you
will not use it on the same day, please disconnect the battery.
Input power and switch
S.HUB duo can output up to 18 PWM channels. When the number of channel on the
BUS is less than 18, there is no output signal on the extra channels.
The frequency of the servo output port is automatically synchronized with the input bus
frequency.For example: When the receiver works in S.Bus 16CH / 18CH mode, the
output port frequency is 15ms. When the receiver works in S.Bus 12CH high-speed
mode, the output port frequency is synchronously increased to 6ms (only digital servos
can be used in this mode), and there is no output from the 13th to 18th servo ports.
The maximum continuous current of single output port is 2.5A and the maximum is 5A.
Excessive current will damage the pins.
Servo output port
No matter which protocol is connected to the receiver, while the S.HUB duo decodes the
PWM servo signal, it encodes channel data into a S.Bus format again and outputs
through the SBUS port. To connect more S.Bus compatible devices, such as: S.HUB
mini (# 21898) or gyroscope. The port allows a maximum 5A operating current.
In addition to obtaining high-quality S.Bus data (dual receiver mode), when the RX
protocol is EX.Bus 24CH, the system will encode 9CH-24CH data into the relay 18CH
S.BUS. In this way, with the use of S.HUB mini, you can make full use of the functions of
24 channels, especially the 19th to 24th channels.
S.Bus signal relay
S.HUB duo's fail-safe strategy is "Hold", and the servo maintains the last position before
the signal loss. Only when the physical connection lines of RX1 and RX2 are all faulty,
the fail-safe protection of S.HUB duo will be activated. Otherwise, the F/S protection of
main receiver will be performed.

S.HUB duo supports three kinds of bus protocols (S.Bus, EX.Bus, SRXL). When
initializing, it will connect to the protocol which is used the last time firstly (quick start
function). If the connection fails, it will automatically switch protocols and attempt to
re-connect.
S.HUB duo supports dual receiver redundancy. When two receivers are connected, RX1
is the master receiver. Of course, it also supports single receiver mode, you can connect
RX1 or RX2 alternatively. There are LED indicators next to the RX1 and RX2 ports,
together with the main LED, indicate and record the signal conditions during the flight.
