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.
