Futaba R7003SB 3K HV S.BUS2 FASSTest User Manual

Futaba R7003SB 3K HV S.BUS2 FASSTest

Instruction

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.

• 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

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 userʼs 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.

• 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.

• 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.

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

   For systems without dual receiver capability, link each receiver in turn.

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

Other than dual receiver function

• Telemetry not available
• Set telemetry to INH (disabled)

Compliance Information Statement (for Canada)
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the
following two conditions:

1. This device may not cause interference, and
2. This device must accept any interference, including interference that may cause undesired operation of the device.

This equipment complies with IC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body.

FASSTest12CH(Telemetry OFF）mode

This mode is forcibly turning off telemetry transmission to prevent
collision of telemetry signals from the receiver to the transmitter when using dual RX link mode in FASSTest12ch mode.

1.  Turn on the receiver. [Transmitter is always OFF]
2. Press and hold the SW for 5 seconds or more.

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.

Dual Rx Link System

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

Connection example

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.

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.
