R7208SB
 FASSTest-2.4GHz Bidirectional Communication System  Dual Rx Link System Equipment  S.BUS2 / S.BUS Port and 8 Channels for Conventional System
Receiver
 Applicable systems: Futaba FASSTest-2.4GHz system transmitter

Thank you for purchasing a Futaba R7208SB FASSTest-2.4GHz compatible receiver. The R7208SB 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 R7208SB can also be switched to the Dual Rx Link System. This system can ensure safety by mounting two receivers on one aircraft.

Usage precaution · Analog servos cannot be used with the R7208SB in the FASSTest
12CH 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 R7208SB 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 R7208SB 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 R7208SB 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.

(Typical installation)

When all ports are used.

Link
FASSTest is a bidirectional communication system between the R7208SB 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
1 Bring the transmitter and the receiver close to each
other, within 20 inches (half meter).
2 Turn on the transmitter. Place the transmitter into
the receiver linking mode.
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.

Channel Modes
The R7208SB 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.
1 Turn on the receiver. [Transmitter is always OFF] 2 Press and hold the SW for 5 seconds to 10 seconds.
3 When the LED of the receiver changes from blinking
red to blinking orange, SW is released.
4 The LED should now blink red two times in the
patterns described in the chart below.
5 Each press of the SW advances the receiver to the
next mode.
6 When you reach the mode that you wish to operate
in, press and hold the SW for more than 2 seconds. When LED blinks in green with red, it is the completion of a mode change, SW is released.
7 Cycle the receiver power off and back on again after
changing the Channel mode.

Dual Rx Link System
By installing two receivers in one aircraft, if one receiver becomes unable to communicate, the other receiver can be operated.

How to change to Dual RX Link mode
1 Turn on the receiver. [Transmitter is always OFF] 2 Press and hold the SW for 5 seconds or more.

Receiver : A

Receiver : B Communicate with two receivers

Even if there is a problem with the B receiver, communication will be performed with the A receiver.
Even if there is a problem with the A receiver, communication will be performed with the B receiver.
In Dual RX link mode, the SB2/RX port is for reception only, so use CH mode B, C, D, F, G mode for S.BUS output and S.BUS2 input/output.
