Castle Creations Futaba S.BUS2 Telemetry Link 010-0152-00
Maybe you want to know the voltage of your onboard battery (s), the RPM the motor is turning or the temperature of your ESC. In this day and age R/C is not just one way communication anymore. 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.
Let’s start from the beginning.
By definition, Telemetry is an automated communications process by which measurements (such as speed, temperature, or battery power) are made and other data collected at remote or inaccessible points and transmitted to receiving equipment for monitoring. A telemeter is a device used to remotely measure any quantity. It consists of a sensor, a transmission path, and a display, recording, or control device. Telemeters are the physical devices used in telemetry.
Telemetry has the potential, not only to improve the safety of our models by monitoring battery voltages, ESC temperature, and other critical parameters, but it also creates other opportunities to get even more fun out of flying because you’ve essentially reduced the risks of “unknown” inevitable crashes. Think of the benefits to be had from alarms that will sound to warn you when there's interference about or if your receiver battery is running unexpectedly low.
First and foremost, we need to review essential compatibility parameters.
Compatible Castle ESC
The ESC must have the ability to accept a bi-directional communication protocol that gives it the ability to transmit real-time telemetry feedback. This feature is called Link Live™ and needs to be enabled on compatible ESCs using Castle Link™. Click here to view the

Compatible Futaba S.BUS2 Radio
S.BUS2™ extends Futaba S.BUS™ and supports bidirectional communication. Compatible radios will support S.BUS2 protocol. It is also necessary to utilize a compatible Futaba® Telemetry Receiver. Click here to view the
Futaba® Radio Compatibility Chart.
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.
And how about this….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™.
