R7003SBFASSTest-2.4GHz Bidirectional Communication System
S.BUS2 / S.BUS Port and Conventional System Receiver
Applicable systems: Futaba FASSTest-2.4GHz systemtransmitterThank you for purchasing a Futaba R7003SB FASSTest-2.4GHz compatible
receiver. The R7003SB 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. R7003SB has a
PHULWZKLFKDFTXLUHVWKHLQIRUPDWLRQIURPWKHPRGHORQÀLJKWE\FRQQHFWLQJDQoptional telemetry sensors. It also includes both standard PWM output ports andS.BUS output ports. 4 ports of R7003SB can choose an output channel from the11 modes.

If R7003SB does not use S.BUS/S.BUS2 system, it canperform only operation of 3 channels. However, if S.BUS/
S.BUS2 system is used, use of the maximum channel ofa transmitter can be performed. You have to use S.BUS/
S.BUS2 servo, in order to use S.BUS/S.BUS2 system.

Usage precaution

Antenna installation precaution• Analog servos cannot be used with the R7003SB in the FASSTest 12CH mode.

Do not cut or bundle the receiver antenna wire.

• The R7003SB receiver can only be used with FASSTest capable transmitters.

WARNING

Do not bend the coaxial cable. It causes damage.

Changes or modiﬁcation not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.

The antennas must be mounted in such a way to assure they are strain
relieved.

The R7003SB receiver should be protected from vibration by foam rubber,
Velcro or similar mounting methods. Protect from moisture.

Keep the antenna as far away from the motor, ESC and other noise sources
as you possibly can.

Keep away from conductive materials to avoid short circuits.

Be sure that the two antennas are placed at 90 degrees to each other.
• The R7003SB has two antennas. In order to maximize signal reception andpromote safe modeling Futaba has adopted a diversity antenna system. This allows thereceiver to obtain RF signals on both antennas and ﬂy problem-free.

Don't connect the servo or gyro which do not correspond to S.BUS2 portS.BUS2.

Antenna installation for carbon fuselage• When the servo and gyro which do not correspond to S.BUS2 are connected to S.BUS2
port, there is a danger of falling by malfunction.

WARNING

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

You must leave 30mm at the tip of the antenna fully exposed. The exposed
antenna should be secured so that it cannot move around or back inside ofyour aircraft.

Do not insert or remove the servo connector while the receiver power isON.
•Since the S.BUS servo switches the operation mode automatically according to thetype of signal (S.BUS signal/PWM signal) from the receiver, if the connector is insertedor removed while the power is ON, an S.BUS connected servo will be erroneously
recognized and may stop.

Link to the transmitter
Easy Link ID allows FASSTest receivers to link to compatible transmitter without pressingthe link button on the receiver.
1 Bring the transmitter and the receiver close to each other, within 20 inches (halfmeter).
2 Turn on the transmitter. Place the transmitter into the receiver linking mode.

3 Turn on the receiver.
4 When the LED of the receiver changes from blinking red to solid green, linking

1 Turn on the receiver. LED lights up red. [Transmitter is always OFF]2 Press and hold the Mode/Link button for 5 seconds to 10 seconds.
*It becomes the mode which makes a mistake in exceeding 10 seconds. In that case, carry out power
supply OFF and redo.

3 The LED should now be early blinking green. Mode/Link button is released.
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 When LED blinks in green with red, it is the completion of a mode change.
7 Please cycle the receiver power off and back on again after changing the EXTVOL Mode.

* Refer to the transmitters operation manual for complete details on how to place the transmitter into thelinking 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 isvery 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.
