WindSim Control Box Manual

Choose what happened and Ocie will guide you through the correct setup or firmware recovery path. The recovery tool restores the OCRacing firmware through the Arduino Nano USB bootloader directly from this page.

Choose setup path Firmware recovery

What do you need to do?

Choose the normal setup guide for a new WindSim. Use firmware recovery only if SimHub Arduino Setup Tool overwrote the OCRacing firmware.

Set up a new WindSim in SimHub

If the WindSim Control Box is brand new, do not restore firmware. Open the setup guide and follow the SimHub Arduino, ShakeIt Wind, fan mapping and wind profile steps.

Open setup guide Use firmware recovery only if SimHub Arduino Setup Tool overwrote the OCRacing firmware.

Before you start: do these 3 things

Close SimHub completely.
Close Arduino IDE and every serial monitor.
Disconnect other Arduino / USB serial devices. The restore tool can overwrite the Arduino-compatible device you select.

Allow access to serial ports

Approve every Arduino / USB serial port in the browser dialog. Ocie can only watch approved ports, so this lets it detect which one disappears and comes back after USB reconnect.

Start detecting

Click Start detecting. Ocie will start watching the approved ports and then tell you when to unplug and plug back the control box.

Detected control box

When the same approved port disappears and comes back, Ocie marks it as the control box and opens the firmware restore step.

Select WindSim Control Box manually

Disconnect every other Arduino / USB serial device first. Then connect only the WindSim Control Box and choose its port from the browser dialog.

Detection Waiting

Bootloader Auto: 115200 then 57600

No device selected

Use automatic detection or manual selection first.

Required before firmware restore Firmware restore is locked until the control box is selected and confirmed. I confirm that I unplugged and plugged back in only the OCRacing WindSim Control Box and that SimHub is fully closed.

Locked: detect or manually select the WindSim Control Box first.

Firmware restored. Test the fans.

Before testing, confirm that the fan wiring and external power are connected. Ocie will test the left fan first and the right fan second.

Required before fan test Fan test is locked until both checks are confirmed.

The test buttons stay disabled until both boxes are ticked.

1. Both fans are plugged into the control box The left fan and right fan cables are connected to the WindSim Control Box. 2. External power is connected The power supply is plugged into the wall socket and into the control box. USB alone will not spin the fans.

Fan tests locked: complete both checks above.

1. Test left fan

Keep fingers clear of the fan, then start the left-side output test.

Locked: complete both required checks above.

Did the left fan spin?

2. Test right fan

After the left fan is confirmed, test the right-side output.

Locked: complete both required checks above.

Did the right fan spin?

Fan hardware test passed.

If the fans do not work in SimHub after this, the firmware and hardware are probably OK and the issue is likely SimHub configuration. Continue with the WindSim SimHub setup manual. If you have any problem, contact us at info@ocracing.eu.
