- Your spectrum ST4 need to be running on RC007_84 or greater.
- Your Inertial Wheels needs to be on Core 0.3.0 and Rx V 0.3.0, but reach out to Boyd for the latest.
- You need a special cable that connects the IW Rx to the ST4's i/o port - a diagram is attached in PDF format.
To get going:
- Plug in the custom cable to the IWRx and the ST4's i/o port
- Power up the RX using USB power - from a compatible battery pack like a Vmount, or Gold Mount with USB A out.
- Power on the IW. Select Menu --> Output --> API or eMotimo spectrum ST4 - Go back to main Dashboard.
- Power up the Spectrum ST4 - check your firmware on startup - should be RC007_84 or greater
- On the ST4 -->Settings, third page down-->I/O port --> Set to "Inertia Wheels", click to set. Note that you only have to set the I/O port once after a firmware upgrade - then it will stick.
- On the ST4, go to main menu, then Live Motion --> Select Preset#7 - Inertia Wheels, click to set. Note that you only have to set the motor profile once after a firmware upgrade - then it will stick.
- Verify that the Inertia Wheels Dashboard says - eMotimo - ST4 okay. When this happens, there is two way communication.
Couple of notes:
- The ratios of the wheels to head are true, meaning a 20:1 on pan will require 20 rotations of the IW for 1 rotation of the Spectrum Pan Axis. Same with Tilt. To get under 1:19, you will have to modify your defaults in Menu-->Wheels --> Fastest Ratio.
- Any Motor profile of the spectrum will work - Quiet Fast, Fastest, etc. We just made a special, ultra responsive profile for IW.
- If you aren't getting communication, from the RX to the ST4, you can reset the ST4's serial port by going to Settings, third page down-->I/O port --> Set and click anything but Intertia Wheels, click to set, then switch back.
- Custom Buttons, Knobs, and workflow to engage other functions of the ST4 and the Wheels.
