1M23N17499 R7108SB ◆ FASSTest-2.4GHz Bidirectional Communication System / FASST(Multi-ch,7ch) -2.4GHz ◆ 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 Antenna installation for carbon fuselage Usage precaution 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. • 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. Be careful of connector insertion WARNING Don't connect an S.BUS servo / gyro to S.BUS2 connector. Changes or modification not approved by the party responsible for compliance could void the user’s authority to operate the equipment. Link precaution The R7108SB receiver should be protected from vibration by foam rubber, Velcro, or similar mounting methods. Protect from moisture. 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. Keep away from conductive materials to avoid short circuits. When the linking is complete, please cycle the receiver power and ensure the receiver is properly linked to the transmitter. Antenna installation precaution Please power up your system in this order: Transmitter first, followed by the receiver. Do not cut or bundle the receiver antenna wire. Do not bend the coaxial cable. It causes damage. 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. The antennas must be mounted in such a way to assure they are strain relieved. Connector precaution 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. Don't connect a connector, as shown in a before figure. ■ It will short-circuit, if it connected in this way. A short circuit across the battery terminals may cause abnormal heating, fire and burns 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.

The full text of the EU declaration of conformity is available at the following internet address: http://www.rc.futaba.co.jp/english/dl/declarations.html Channel Modes 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. 4 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. 6 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.

Link to the transmitter : FASSTest Bring the transmitter and the receiver close to each other, within 20 inches (half meter). 2 Turn on the transmitter. linking mode. Place the transmitter into the receiver 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 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. Default Systems (FASSTest ⇔ FASST) change method 1 Turn on the receiver. [Transmitter is always OFF] 2 Press and hold the Link/Mode button for 10 seconds to 15 seconds. 3 When the LED begins to blink green the button may be released. 4 The LED should now be blinking green in one of the patterns described by the chart below. ( Default : FASSTest ) 5 Each press of the Mode/Link button advances the receiver to the next system. 6 When you reach the system that you wish to operate in, press and hold the Mode/Link button for more than 2 seconds. When the LED blinks green and red, the system change is complete. Release the Mode/Link button. 7 Please cycle the receiver power off and back on again after changing the system.
