How to Dual Rx Link

1. Install two receivers on the aircraft as shown in the
wiring diagram.
2. Link the two receivers using the dual receiver feature
of the transmitter.
For systems without dual receiver capability, link
each receiver in turn.

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.
Turn on the sub

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.

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.
