What is S.BUS?
Unlike conventional radio control systems, the S.BUS system
uses data communication to transmit control signals from a
receiver to a servo, gyro, or other S.BUS compatible device.
This data includes commands such as “move the channel 3
servo to 15 degrees, move the channel 5 servo to 30 degrees”
to multiple devices. The S.BUS devices execute only those
commands for their own set channel. For this reason, it can
be used by connecting multiple servos to the same signal
line.

Can also be used together with conventional servos. However, conventional servos cannot be used by the S.BUS output.

When using servos with a remote battery pack, use S.BUS Hub with Cable (2-way/remote battery pack use).
Please refer to the instruction manual of S.BUS Hub with Cable (2-way/remote battery pack use) for the connection method.

Link to the transmitter
Easy Link ID allows FASSTest receivers to link to compatible
transmitter without pressing the link button on the receiver.

Channel Modes
The R7008SB is capable of changing its channel allocations as described
in the table below. This is especially important when using the receiver
in a dual receiver mode. See your transmitter operation manual for
complete details on operating in the dual receiver mode.

FASSTest
FASSTest is a bidirectional communication system between the R7008SB
receiver and FASSTest capable transmitters. Multiple optional telemetry
sensors may be connected to the S.BUS2 on the receiver and that data is
in turn displayed on the transmitter.
*Pleaseseeyourtransmittersoperationmanualtoconguretransmitterto
operatewithtelemetrysensors.
S.BUS2
S.BUS2 extends S.BUS and supports bidirectional communication.
Sensors are connected to the S.BUS2 port.
*OnlyS.Bus2capabledevicesmay beconnectedtothe S.Bus2 port.

WARNING
󾛹
Turnonthepowerintransmitter → receiverorder.Inaddition,alwayschecktheoperationofalltheservosbeforeight.
󾛻
DonotinsertorremovetheservoconnectorwhilethereceiverpowerisON.
Since the S.BUS servo switches the operation mode automatically according to the type of signal (S.BUS signal/PWM signal) from the receiver, if the connector is
inserted or removed while the power is ON, an S.BUS connected servo will be erroneously recognized and may stop.
