R7008SBFASSTest-2.4GHz Bidirectional Communication System
S.BUS2 / S.BUS Port and 8 Channels for Conventional System Receiver10211

Thank you for purchasing a Futaba R7008SB FASSTest-2.4GHz compatible receiver. The R7008SB receiver features bi-directional communication
with a FASSTest Futaba transmitter using the S.Bus2 port. Using the S.Bus2 port an impressive array of telemetry sensors may be utilized. It also
includes both standard PWM output ports and S.Bus output ports.

WHILE LINKING THE RECEIVER TO THE NEW TRANSMITTERFASSTestS.BUS2FASSTest 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 isin turn displayed on the transmitter.

S.BUS2 extends S.BUS and supports bidirectional communication.
Sensors are connected to the S.BUS2 port.

0LEASE SEE YOUR TRANSMITTERS OPERATION MANUAL TO CONlGURE TRANSMITTER TOOPERATE WITH TELEMETRY SENSORS/NLY 3"US CAPABLE DEVICES MAY BE CONNECTED TO THE 3"US PORT3TANDARD 3"US SERVOS AND GYROS SHOULD NOT BE CONNECTED TO THE 3"USport.

What is S.BUS?
Unlike conventional radio control systems, the S.BUS system
uses data communication to transmit control signals from areceiver 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 thosecommands for their own set channel. For this reason, it canbe used by connecting multiple servos to the same signalline.
