FASSTest-2.4GHz Bidirectional Communication System / FASST(Multi-ch,7ch) -2.4GHz

R7108SB

◆

S.BUS2 / S.BUS Port and 8 Channels for Conventional System Receiver

◆

Thank you for purchasing a Futaba R7108SB FASSTest-2.4GHz compatible receiver. The R7108SB 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 (1-8ch) and S.BUS output ports. The R7108SB 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

Usage precaution

• Analog servos cannot be used with the R7108SB in the FASSTest 12CH / FASST High-speed mode.

• Don't connect to Extra Voltage before turning on a receiver.

WARNING

Changes or modification not approved by the party responsible for

compliance could void the user’s authority to operate the equipment.

The R7108SB receiver should be protected from vibration by foam

rubber, Velcro, or similar mounting methods. Protect from moisture.

Keep away from conductive materials to avoid short circuits.

Antenna installation precaution

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.

■ The R7108SB 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.

Antenna installation for carbon fuselage

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 of your aircraft.

Be careful of connector insertion

Don't connect an S.BUS servo / gyro to S.BUS2 connector.

Link precaution

Do not perform the linking procedure while the motor's main power is 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 rst, followed by the receiver.

If the R7108SB receiver was previously linked to another transmitter, make sure that transmitter is not operating while linking the receiver to the new transmitter.

Connector precaution

Don't connect a connector, as shown in a before gure.

■ It will short-circuit, if it connected in this way. A short circuit across the battery terminals may cause abnormal heating, fire and burns

DANGER

Receiver

Do not insert either a switch or battery in this manner.

The R7108SB 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.

Turn on the receiver. [Transmitter is always OFF]

Press and hold the Mode/Link button for 5 seconds to 10

seconds.

When the LED of the receiver changes from blinking red to

blinking red with green, Mode/Link button is released.

The LED should now blink red two times in the patterns

described in the chart below.

Each press of the Mode/Link button advances the receiver to

the next mode.

When you reach the mode that you wish to operate in, press

and hold the Mode/Link button for more than 2 seconds. When LED blinks in green with red, it is the completion of a mode change, Mode/Link button is released.

Please cycle the receiver power off and back on again after

changing the Channel mode.

FASSTest

FASSTest is a bidirectional communication system between the R7108SB 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.

Link to the transmitter : FASSTest

Bring the transmitter and the receiver close to each other,

within 20 inches (half meter).

Turn on the transmitter. Place the transmitter into the receiver

linking mode.

Turn on the receiver.

The receiver will wait for the linking process to begin for 2

seconds. Following that it will return to the normal operation mode.

(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, 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 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.

S.BUS2

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

Link to the TMA-1 Telemetry Adapter

R7108SB has to be FASSTest.

First, a transmitter and a receiver are linked.

Transmitter is turned off.

Press and hold the Mode/Link button of R7108SB for 15 seconds.

After the R7108SB LED lights in this sequence, Red Blink -- Red with Green

Blink -- Green Blink -- Red Blink, release the Mode/Link button.

When in link mode with the R7108SB, the TMA-1 LED blinks green along with

the red LED of the receiver.

Push the TMA-1 link button as long as necessary for its LED to blink.

Completion of a link will change LED of TMA-1 green from red only for a

moment.

Please cycle the receiver power.

FASST

R7108SB also can use the FASST-Multi/7ch mode. The FASST mode does not support the telemetry functions. The FASST system has a normal mode and a high-speed mode. However, in the High-speed mode, analog servos cannot be used.

Link to the transmitter : FASST

Bring the transmitter and the receiver close to each other,

within 20 inches (half meter).

Turn on the transmitter and receiver.

Link operation is performed by the Link/Mode switch.

• When using TM-8 module, it's possible to set F/S position (only 3CH).
