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 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 users 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 first, 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 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 DANGER Receiver Do not insert either a switch or battery in this manner.

Link to the transmitter : FASSTest 1 Bring the transmitter and the receiver close to each other, 2 Turn on the transmitter. 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.
