Use this guide when your platform does not start, connect, initialize, or move correctly. Begin with the basic checks below, then select the symptom that best matches your issue.
Begin With These Basic Checks
Before changing any settings:
- Turn off the platform and disconnect it from power for at least 30 seconds.
- Check that all motor, sensor, power, and USB connections are fully seated.
- Connect the platform directly to the computer—do not use a USB hub or extension cable.
- Fully close Sim Racing Studio (SRS), SimHub, SMC3Utils, DOF Reality Tools, and any other 3rd party applications that use telemetry (CrewChief, SimHaptics, FFB Software, etc.).
- Restore power, open only SRS and run the hardware movement test.
If the platform moves correctly during the SRS test, the hardware is generally communicating, and the issue is more likely related to SRS, telemetry, or simulation configuration.
Find Your Issue
1. The platform has no power
Confirm that the power cables are connected securely, the electrical outlet works, and the power-supply LEDs are illuminated. Test the outlet with another device if necessary.
If a power-supply LED remains off, proceed to Connection – Platform Will Not Start, Initialize, or Move
2. The computer or Sim Racing Studio does not detect the platform
Reconnect the USB cable directly to the computer, try another USB port, and restart the computer. In Windows Device Manager, check whether the control unit appears under Ports (COM & LPT).
If it is missing, appears with an error, or repeatedly disconnects, continue to Connection — Platform Not Detected by PC or SRS
3. The platform moves in Sim Racing Studio but not in a game
Confirm that the simulation is supported and displays Ready to play in SRS. Start SRS before launching the game and confirm that SRS receives telemetry after entering an active session.

For simulation detection, telemetry, licensing, firewall, or SRS configuration problems, contact Sim Racing Studio Support before contacting DOF Reality.
4. Motion worked previously but has stopped
Restart the platform and computer. Check whether Windows still detects the platform and whether it moves during the SRS motion test.
Also consider any recent Windows, SRS or game updates along with any USB connection, firmware, or hardware changes.

5. Sim Racing Studio will not install or open
Restart Windows and confirm that antivirus or security software has not blocked or quarantined SRS. Download the latest version of Sim Racing Studio and reinstall.

6. One motor or axis does not move
Turn off and disconnect the platform, then inspect that motor’s power and sensor connections. Compare them with the correctly operating motors, but do not change the wiring or connector arrangement.
Motors and Calibration — Motor Errors, Uneven Movement, or Unusual Behavior
For a motor that remains completely stuck, continue to Motors and Calibration — Sensor-Based Motor Stuck.
7. “MOT ERR” error
Check all motor power and sensor connections. Perform the Motors and Calibration — “MOT ERR” Troubleshooting.
8. The platform is uneven, unbalanced, or moves incorrectly
Check that the frame is assembled correctly, the motor arms are positioned properly, and the seat and controls are securely installed. Make sure the platform’s load is reasonably balanced and cables do not restrict movement.
If the platform moves correctly in the SRS test but incorrectly in a simulation, continue to Games and Software — Platform Movement Is Unbalanced or Incorrect.
If a motor arm is not level in the neutral position, refer to Motors and Calibration — Motor Arm Is Not Level in the Neutral Position.
9. The control box is beeping
Count the beeps and note if they are long or short. Turn off the platform and inspect the connected motors, power cables, and sensor connections. Refer to Power and Control Box — Decode Control Box Beep Codes.
Do not replace components or modify control-box wiring unless instructed by DOF Reality Support.
10. The issue started after a firmware update
Restart the control unit and confirm that Windows detects it correctly. Do not repeatedly reinstall firmware or use firmware intended for another controller or motor type.

11. The issue started after a platform upgrade
Confirm that every upgraded component is installed and connected according to its instructions. Check the motor type, sensor or encoder connections, controller configuration, and required firmware.

12. The motors make small movements while idle
Small position corrections can occur while the platform is powered. Turn the platform off when it is not in use and never leave it powered while unattended.
