R7106SB◆ FASSTest-2.4GHz Bidirectional Communication System / FASST(Multi-ch,7ch) -2.4GHz◆ S.BUS2 / S.BUS Port and 6 Channels for Conventional System ReceiverThank you for purchasing a Futaba R7106SB FASSTest-2.4GHz compatible receiver. The R7106SB 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 (1-6ch) and S.BUS output ports. The R7106SB can also be switched to the FASST(Multi-ch/7-ch) System.
● Applicable systems: Futaba FASSTest-2.4GHz / FASST (Multi-ch,7ch) -2.4GHz system transmitter• Analog servos cannot be used with the R7106SB in the FASSTest
12CH / FASST High-speed mode.

■ The R7106SB has two antennas. In order to maximize signal reception
and promote safe modeling Futaba has adopted a diversity antenna system.
This allows the receiver to obtain RF signals on both antennas and fly
problem-free.

WARNING

Antenna installation for carbon fuselage

Usage precaution

Changes or modification not approved by the party responsible forcompliance could void the userʼs authority to operate the equipment.
The R7106SB receiver should be protected from vibration by foamrubber, Velcro, or similar mounting methods. Protect from moisture.

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

Be careful of connector insertion
Don't connect an S.BUS servo / gyro to S.BUS2 connector.

Keep away from conductive materials to avoid short circuits.

Link precaution

Antenna installation precaution

Do not perform the linking procedure while the motor's main power isconnected or the engine is operating as it may result in serious injury.

Do not cut or bundle the receiver antenna wire.
Do not bend the coaxial cable. It causes damage.
The antennas must be mounted in such a way to assure they are strain
relieved.
Keep the antenna as far away from the motor, ESC and other noise
sources as you possibly can.
Do not touch the antenna to metal, carbon, or other conductive material.
Be sure that the two antennas are placed at 90 degrees to each other.

When the linking is complete, please cycle the receiver power andensure the receiver is properly linked to the transmitter.
Please power up your system in this order: Transmitter ﬁrst, followedby the receiver.
If the R7106SB receiver was previously linked to another transmitter,
make sure that transmitter is not operating while linking the receiver tothe new transmitter.

FASSTest

The R7106SB is capable of changing its channel allocations asdescribed 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 is a bidirectional communication system between theR7106SB receiver and FASSTest capable transmitters. Multiple
optional telemetry sensors may be connected to the S.BUS2 on thereceiver and that data is in turn displayed on the transmitter.

5 When the LED of the receiver changes from blinking red tosolid green, linking is complete.

(A link waiting state is ended in 1 second.)• Refer to the transmitter's 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, yourreceiver 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 linkto the wrong transmitter. This is very dangerous if not noticed. To avoid
the problem, we strongly recommend that you 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.

Sensors are connected to the S.BUS2 port.

5 After the R7106SB LED lights in this sequence, Red Blink -- Red with Green
Blink -- Green Blink -- Red Blink, release the Mode/Link button.

6 When in link mode with the R7106SB, the TMA-1 LED blinks green along withthe red LED of the receiver.

7 Push the TMA-1 link button as long as necessary for its LED to blink.
8 Completion of a link will change LED of TMA-1 green from red only for amoment.

9 Please cycle the receiver power.
FASST
R7106SB also can use the FASST-Multi/7ch mode. The FASST mode does
not support the telemetry functions. The FASST system has a normal mode anda high-speed mode. However, in the High-speed mode, analog servos cannot beused.
