How to Dual Rx Link

1
Install two receivers on the aircraft as shown in the
Connection Example.
2
Link the two receivers using the dual receiver
feature of the transmitter.
For systems without dual receiver capability, link
each receiver in turn.
Transmitter in link mode
For FASSTest 18CH Select dual mode and link primary
*Follow the link procedure
for each receiver manual.

◆ About telemetry system

When using the dual receiver function
・The telemetry function of the main receiver can be used
・Sub-receiver telemetry function is not available
Telemetry for FASSTest12CH
In FASSTest12CH mode, after linking R7214SB in telemetry
OFF mode, link the receiver you want telemetry to. (The
transmitter will show the telemetry of the last linked transmitter.)

Usage precaution

Turn on the main
receiver and link • Analog servos cannot be used with the R7214SB 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 R7214SB 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.
Turn on the sub
Antenna installation precaution
receiver and link
Do not cut or bundle the receiver antenna wire.
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 R7214SB 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.

*Be sure that when using ESCs regulated
output the capacity of the ESC must meet
your usage condition.
*Never use dry batteries for the power sup-
ply of the R7214SB as they may cause
difficulties.

Thank you for purchasing a Futaba R7214SB
FASSTest-2.4GHz compatible receiver. The
R7214S B r e c e i v e r f e a t u r e s b i - d i r e c t i o n a l
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 (1-14ch) and S.BUS output ports. The
R7214SB can also be switched to the Dual Rx
Link System. This system can ensure safety by
mounting two FASSTest receivers on one aircraft.

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.
Power on the system in this order: Transmitter first, followed by the
receiver.
If the R7214SB 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
this 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.
