Alpha Link s.BUS Setup

MOVI Pro / XL

INTRODUCTION

For most customers, by telling us what gimbal you have purchased, we will pre-configure your Alpha Link S.Bus for you. However, if you are having difficulty, you can follow these steps to set up your Alpha Wheels and Alpha Link for your gimbal. 

UPDATE YOUR ALPHA WHEELS FIRMWARE

Alpha Link S.Bus Requires AW Firmware 1.2 or newer

Download TyQT for your operating system from the Downloads page.

Download the newest firmware for your Alpha Wheels from the Downloads page.

Follow the instructions in this video: 

ADJUST MOVI SETTINGS

You will need to make some adjustments to certain settings in your MōVI app. Under the Dual Op > Adjustments menu:  

Pan/Tilt Joystick > Window: 0

This should never be anything but 0.

Pan/Tilt Joystick > Expo: 0

If you would like to be able to do small moves and very fast moves all at one speed, increase this. Keep in mind, this will remove repeatability.

Remote Rate Scale: 100

You can adjust this setting to make the MōVI respond slower or faster to the default speeds. 200 will go twice as fast. 50 will go half as fast. 

Pan/Tilt Joystick > Smoothing: 0

Feel free to adjust this if you would like smoothing on the wheels. Keep in mind, this will remove repeatability.

GEAR RATIOS

When your Alpha Link and Gimbal are setup properly according the instructions above, the gear ratios will have a range of speeds that line up with conventional Arri gear heads with some additional speeds.
