TELEMETRY Link XBUS, Spektrum Compat,010-0148-00

Telemetry Link for Spektrum X-BUS

Overview:
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 transmit signals from the controller to the receiver, but Telemetry-capable systems also send real-time data from your model back to your transmitter.

The X-BUS Telemetry Link was developed based on communication protocol disclosed from Spektrum® for use with specific Spektrum® radios and compatible Castle Creations ESC’s. Telemetry data can be displayed on the transmitter screen, or notify you 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.

Why should I integrate Telemetry into my models?
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 it essentially reduces the risk of “unknown” inevitable crashes. Think of the benefits to be had from alarms that will sound to warn you if your ESC is running hot or if your receiver battery is running unexpectedly low.

Note: Not officially compatible with any Spektrum surface transmitters. Compatibility requires specific software in the transmitter that has not been provided by Spektrum for any of their surface transmitters.

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™. The Telemetry Link will not work if the ESC is programmed for Multirotor or External Governor Mode due to the higher PWM frequency.

At this time Spektrum has only added Telemetry Link support to some of their air transmitters; there are no surface transmitters currently compatible with the Telemetry Link.

Below is an example of an X-BUS 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 Spektrum® X-Bus™ receiver and Telemetry Module/System.

And how about this….there is no requirement for additional Telemetry Sensors for your Spektrum® radio when using the X-BUS Telemetry Link. There are 7 specific data points available* and you can enable/disable to your liking through Castle Link™.
