Futaba Telemetry

From version 2.4.3 you can utilize full support of the Futaba Telemetry!

This mean you can see all telemetry variables sent by Spirit units with S.BUS2 (FASSTest receiver) in real-time.

1 Requirements

To make it work you will need:

• Futaba transmitter: 14SG, 18MZ or 18SZ
• FASSTest receiver: R7003SB, R7006SB, R7008SB, R7014SB or R7018SB.
• FrSky Integration cable available in our stores (with a small modification).
• Spirit firmware: 2.4.3.

2 Cable modification

To allow telemetry transmission the FrSky Integration cable must be modified. For this purpose you will need a servo' plastic plug (already included with the cable).

Modification of the shorter end

1. Use a needle to free-up the Red and Orange wires from the plastic.
2. Then plug the Red wire from the middle to the previous position of the Orange.
3. Plug the Orange wire to a separate servo plastic (at signal position).

Resulting cable modification

3 Wiring

The FrSky Integration cable is able to transfer everything including channel data and telemetry. This mean that you will not need to connect anything else except this cable.

Shorter lead of the cable	receiver - S.BUS2
Longer lead of the cable	unit - RUD and ELE/PIT/AIL (see the photo)

Make sure that the receiver is bound in the FASSTest mode, otherwise telemetry will not work.

Spirit: If S-BUS Adapter is used with Spirit, then it will be replaced by the FrSky Integration cable.

Spirit Pro & uSpirit: Servo cable that was used for connection between receiver and unit will be replaced by the FrSky Integration cable.

4 Transmitter preparation

4.1 Configuration

Power up the transmitter and in the Main menu enter the Sensor page.

Configure:

• 1: ESC
• 2: Text Gen

At this point your transmitter is ready. You can return to the main screen.

5 Telemetry data

In order to display Telemetry data, move the roller while on the Main screen until you will see ESC Status.

If you can't see the ESC Status, please make sure you have performed necessary configuration.

List of available Telemetry variables:

• RPM [Head RPM] - RPM provided by RPM sensor or ESC.
• Volts [V] - ESC Telemetry | Main Battery voltage
• Motor [A] - ESC Telemetry | Main Battery current
• Throttle [%] - Throttle percentage sent to the ESC.
• Output [%] - (Vibration level 0 - 10% is normal level)
• FET Temp [°C] - ESC Telemetry | FET temperature
• BEC [C] - ESC Telemetry | Main Battery consumed capacity (1234mAh = 123.4C)
• BEC [V] - ESC Telemetry | BEC Voltage
