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)

The FrSky Integration cable is not able to carry power to the receiver. For this purpose you will need to add a normal servo cable between receiver and unit to a free port (for example AUX, AUX2 or CH0 port connected with 8/SB). Alternatively you can use one additional wire and connect it to the middle pin of the RUD that is not connected. You can also use a secondary BEC output so no other cable is required.

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

1. Power up the transmitter and from the Main screen go to the LINKAGE MENU (LNK button) and then to the SENSOR page.
2. At the 1th position slot select ROXXY ESC as the Sensor. This will overwrite automatically 5 slot positions.
3. For the 6th position slot select SBS-01V as the Sensor. This will overwrite automatically next 2 slot positions. So that 7 slot positions will be utilized.

At this point your transmitter is ready.

5 Telemetry data

Now it is a proper time for configuring the ESC Telemetry (if you want to use this feature).

In order to display Telemetry data, go to the LINKAGE MENU and then TELEMETRY page.

List of available Telemetry variables:

• Rx-BATT [V] - BEC Voltage (provided by the receiver)
• EXT-VOLT [V] - Voltage measured on external wires (optionally connected to the receiver)
• CURRENT [A] - ESC Telemetry | Main Battery current
• VOLTAGE [V] - ESC Telemetry | Main Battery voltage
• CAPACITY [mAh] - ESC Telemetry | Main Battery consumed capacity
• RPM [Head RPM] - RPM provided by RPM sensor or ESC.
• TEMP [°C] - ESC Telemetry | FET temperature of the ESC

• BATTERY [V] - ESC Telemetry | BEC Voltage (provided by unit)
• EXT-VOLT [%] - (Vibration level 0 - 10% is normal level)
