2.) choose the previous downloaded “*.shmotioncontroller” file in the browser

3.) open the file

9. Select your comport #

For geting the best experience through various platform sizes, it is important to configure the distances between the actuators which vary between different rigs

1.) Press on “Settings” of your Motion controller

2.) Navigate to Controllers and choose the COM port the control unit is connected to via USB, in most cases it is shown as “FTDI”, if you can not find it, use the “identifiy” button

3.) Then press “Edit axis assignments”

4.) Axis are already assigned, please press “Ok”

10. Test the platform #

Now we can do a function test

1.) Navigate to “Motion”

2.) Press “Enable Motion”

3.) Go to “Manual Control”

4.) Use the sliders to increase slowly the tension of the seatbelt on each site

5.) Use the slider to adjust the belt center. This helps reduce friction in the seatbelt system so there is no dead zone when a signal is applied.
Increase the offset gradually until the seatbelt starts to pull. Then, decrease the offset slowly until the pull just disappears.

11. Ready to tension #

Congratulation, your seatbelt is now ready for your favourite games. Some games need additional steps to activate telemetry data for simhub. Follow instructions on the simhub software.
