Traditional radio systems just transmit signals to the receiver, but Telemetry-capable systems send real-time data from your model back to your transmitter. The S.BUS2 Telemetry Link was developed based on communication protocol disclosed from Futaba for use with specific Futaba S.BUS2 radios and compatible Castle Creations ESCs. Telemetry data can be displayed on the transmitter screen, or for parameters where you only want to be notified when a defined threshold is exceeded, (battery voltage, ESC temperature, etc.) you can configure a vibration or sound alert from the radio.
Items needed for set-up and operation.
Below is an example of a S.BUS2 Telemetry Link set-up for Surface, Air and Internal Governor Systems. You can see how the Telemetry Link (about 5.4 inches long) connection is made between the Castle ESC and the Futaba® S.BUS2™ receiver. There is no requirement for additional Telemetry Sensors for your S.BUS2™ radio when using the S.BUS2 Telemetry Link. There are 7 specific data points available* and you can enable/disable to your liking through Castle Link™.
Note: data points available may vary depending on the ESC's capabilities.
|Futaba S.Bus2 Telemetry Link Data Points|| |
|Battery Voltage||You will be able to see the voltage state of your battery during flight and respond appropriately to deteriorating conditions or alarms you’ve programmed in your radio.|
|Battery Current||Reduce the load (throttle usually) to prevent an over-current shut down and know immediately if your consuming too much current in a particular maneuver. |
|Motor Power Output||This is the percentage of full power your ESC is delivering to your motor.|
|RPM||Ensure you are within acceptable parameters, without the use of a tachometer. |
|BEC Voltage||Monitor your BEC voltage and its stability to the RX even under different loads from different servos.|
|ESC Temperature||ESC temperature monitoring can eliminate a potential thermal shut down. |
|Battery Ripple||Just how hard are the capacitors, FETS, and internal components working with your set up, excessive ripple can cause internal heating of batteries. Excessive heat is harmful to the components and it can ultimately kill the controller.|Specifications:
