Futaba R7008SB - Manual (Page 2)

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.

* Set the channel of S.BUS servos by using an SBC-1 channel changer, CIU-2 USB serial interface or the programming software resident in the 18MZ transmitter.
* 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.
 WARNING
 Do not perform the linking procedure while the motor's
main wire connected or the engine is operating as it may
result in serious injury.
 When the linking is complete, please cycle the receiver
power and ensure the receiver is properly linked to the
transmitter.
 Please power up your system in this order. Transmitter
first, followed by the receiver.

Link to the transmitter
Easy Link ID allows FASSTest receivers to link to compatible
transmitter without pressing the link button on the receiver.
1
Bring the transmitter and the receiver close to each other,
within 20 inches (half meter).
2
Turn on the transmitter. Place the transmitter into the receiver
linking mode.
3
Turn on the receiver.
4
The receiver will wait for the linking process to begin for 2
seconds. Following that it will return to the normal operation
mode.
5
When the LED of the receiver changes from blinking red to
solid green, linking is complete.
(A link waiting state is ended in 1 second.)
• Refer to the transmitters operation manual for complete details on how to place the
transmitter into the linking mode.
• If there are many FASSTest systems turned on in close proximity, your receiver
might have difficulty establishing a link to your transmitter. This is a rare occurrence.
However, should another FASSTest transmitter/receiver be linking at the same time,
your receiver could link to the wrong transmitter. This is very dangerous if you do
not notice this situation. In order to avoid the problem,we strongly recommend you
to double check whether your receiver is really under control by your transmitter.
• If the System Type of the transmitter is changed, the receiver will need to be re-
linked to the transmitter.
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.
1
Press and hold down the Link/Mode button on the R7008SB
receiver.
2
Turn the receiver on while holding down the Link/Mode button.
After power up, the button can be released.
3
The LED should now be blinking red in one of the patterns
described by the chart below.
4
Each press of the Mode/Link button advances the receiver to
the next mode.
5
When you reach the mode that you wish to operate in, press
and hold the Mode/Link button for more than 2 seconds.
6
Once locked into the correct mode the LED will change to a
solid color.
7
Please cycle the receiver(s) power off and back on again after
changing the Channel 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 configure 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.
Standard S.Bus servos and gyros should not be connected to the S.Bus2
port.
 If the R7008SB receiver was previously linked to another
transmitter, make sure that transmitter is not operating
while linking the receiver to the new transmitter.

 WARNING
 Turn on the power in transmitter → receiver order. In addition, always check the operation of all the servos before flight.
 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.
