The Alpha Link S.Bus and S.Bus XR are the first and only all-digital, purpose-built wireless system designed specifically to transmit wheel data to gimbals. They pair perfectly with the Alpha Wheels and Ronin, Gravity, and MōVI Gimbals.

All Digital = Better Performance

Faster response, repeatable moves, no drifting. The Alpha Link S.Bus is an end-to-end all digital system. This means that the absolute position data is communicated directly from the wheels to your gimbal.  With other wheels that use off-the-shelf RC transmitters, wheel data is converted to analog and averaged before being sent to the gimbal.  This results in drifting and a sluggish response. With the Alpha Link S.Bus you get the best performance, with the simplest setup.

Never Adjust Trim

You no longer have to adjust trim. Without any analog link in the wireless chain, trim issues are eliminated entirely.

Simple Setup

The Alpha Link S.Bus requires a simple short setup process once and is saved to your Alpha Wheels memory.

Dedicated Speed Knobs

Quickly and easily adjust the pan tilt speed/direction using the dedicated knobs on the Alpha Link S.Bus.

Intelligent Wireless System

The Alpha Link S.Bus uses cross-industry proven wireless modules. The transmitters use powerful FHSS (Frequency Hopping Spread Spectrum) technology that automatically jumps across wireless bands every 13ms to reduce interference. Each time data is sent, it is checked for errors and resent if necessary on a different band. All invisibly to ensure your wheels and gimbal work in perfect harmony.

Q: How will it connect to the Alpha Wheels?
A: The Alpha Link S.Bus and S.Bus XR have a built in Lemo cable that plugs into the EXT port on the back of the Alpha Wheels.

Q: How will it connect to my gimbal?
A: The Alpha Link S.Bus has a standard S.Bus port on it. Users will need to supply a short s.bus cable that fits their gimbal. S.Bus Cable for Ronin/MOVI M5, M10, M15. S.Bus Cable for MōVI Pro. Tilta Gravity users will need to contact Tilta for S.Bus Cable.

Q: Does this work with all MōVI models?
A: Yes. Including the MōVI Pro.

Q: How is the transmitter powered?
A: The transmitter is powered through the Alpha Wheels.

Q: How is the receiver powered?
A: The receiver is powered through the S.Bus (or D.Bus) port on your gimbal.

Q: Can it work with other gimbals besides the MōVI, Ronin, or Gravity?
A: Not officially, you’re welcome to attempt to do so. The S.Bus signal generated by the Alpha Link conforms to industry standards. The only reason we have limited it to those gimbals is that each has particular channel mapping and scaling settings that we have mapped and programmed into the Alpha Link.

Q: Is there really no need for trim?
A: No need. The signal is all digital from hand wheels to gimbal.
