Antenna installation (1) Locate the antenna connector at the back of your Simucube 2 wheel base. (2) Take the supplied antenna (Disclaimer: use ONLY the supplied antenna) and insert it into the antenna connector. Make sure you are inserting it in a straight orientation. Gently twist the knurled surface at the end of the antenna in clockwise direction approximately 3 turns.

4. Connect power supply/supplies to 110 - 240 V AC outlet with protective earth (PE). 5. Fix steering wheel (not included) to Simucube Quick Release™ (SQR™). If required, install Spacer and/or 70 mm Adapter between the SQR wheel side part and the wheel.

SQR – Wheel side assembly Figure 7 SQR assembly options The included wheel side SQR (Simucube Quick Release) system can be assembled in multiple configurations to best suit your wheel and button box combination. Standard configurations (Figure 7) include (1) 50.8 mm PCD (pitch circle diameter) front mounting without the spacer, (2) 50.8 mm PCD front and back mounting with the spacer and...
Page 14
SQR – 50.8 mm PCD front mounting, no spacer It is possible to use the SQR without a spacer, but the use of the spacer is recommended as it gives the user more space to use the locking pin. To attach the wheel side plate to your wheel, use suitable M5 screws and washers (3 or 6 screws depending on your wheel type) from the included ones or use your own if suitable length is not found.
Page 15
SQR – 50.8 mm PCD front and rear mounting, with spacer To rear-mount your wheel (if you have threads in the rear of your wheel/button box), you will need 3 or 6 M5 screws with a length depending on your wheel and button box thickness and 1 washer per screw.
Page 16
To front-mount your wheel, you will need 3 or 6 M5 screws and a washer per screw. The right length for these screws is approximately 35-39mm + the thickness of your wheel and button box since the screws attach to the threads in the wheel side plate. Use four of the included 10mm long M5 screws and 4 washers to attach the wheel side plate to the spacer as illustrated.
Page 17
SQR – 70 mm PCD front and rear mounting, with spacer To front-mount your wheel, you need 6 M5 screws with a length depending on your wheel and button box thickness, 2 washers per screw and 1 locking nut per screw. Align the eight middle threaded holes as in the image and attach the screws in the order as illustrated.
Page 18
In both cases use four of the included 25 mm long M5 screws and 4 washers to attach the wheel side plate to the spacer as illustrated. Note: Do not use excessive torque to avoid damaging the threads in the SQR aluminum parts. In both cases use four of the included 10 mm long M5 screws and 4 washers to attach the wheel side plate to the spacer as illustrated.

Completed SQR setup for 70 mm PCD wheel. SQR – 70 mm PCD with no spacer Due to the diameter of the wheel side SQR plate, use of the 70 mm adapter without the spacer is not possible with the included hardware.
Page 20
SQR – Motor side assembly When installing the SQR (Simucube Quick Release) system ensure that the motor shaft diameter is compatible with the SQR. The SQR motor side can be disassembled and re-installed in case of slipping or other problems relating to tightness, or if for some reason the black hub has slipped too close to the motor and appears to be touching it.
Page 21
Clean the motor shaft and the cone clamp from possible grease with a dry paper towel. Insert the cone clamp to the motor shaft. If installing to anything else than the Simucube 2 wheelbase, ensure that the clamp is in the middle of the shaft.
Page 22
Insert a paper towel or any suitable thin and soft sheet to prevent the SQR outer tube touching the front plate of the motor. Insert the adapter around the cone clamp and the motor shaft. Tighten the four cone clamp bolts evenly, starting from opposite sides.
Page 23
Remove the paper towel, insert the motor side plate and tighten its three bolts.
The software is available as a zip file from https://www.simucu.be website. Unzip the file and start the Simucube 2 True Drive application. It is important to unzip the file – do not launch the application from inside the zip file.

3) One minute after 2), Simucube will go to standby mode with a long beep. In standby mode Simucube can be activated by toggling the e-stop or via a separate button in True Drive software. Standby mode can be avoided by turning the wheel left/right fast or if Simucube receives torque commands from games.

Taking the first test drive This short section is a introduction to the features of the Simucube system. The first test drive can be done with any simulator, but we recommend Assetto Corsa, Assetto Corsa Competizione, iRacing, or Project Cars.

If a Simucube Wireless Wheel is connected, its name, connection quality and battery status is shown on under the wheel image. For some Simucube Wireless Wheels, a customized image of the wheel is shown in place of the generic wheel.

Figure 9 Simucube Wireless Wheel Management The user interface of Simucube Wireless Wheels in shown in the above figure. Scanning of new devices is an ongoing process, and the list of found devices is shown. It is possible to manually disconnect from the currently connected wireless wheel and to forget the currently connected wheel.
Page 29
If a wireless wheel and a Simucube 2 do not know each other, they can be connected by double clicking the wheel name from the True Drive software, or by the separate button below the list of found devices.
Profile management Simucube 2 has powerful profile management system that allows the driver to set up multiple profiles for use. Figure 10 Profile management tab Main functions of the profile settings: • Profile can be switched from the dropdown selector •...
Page 31
Simple and Advanced Profile Settings Figure 11 Simple Profiles mode Starting from version 1.0.10, True Drive software allows users to adjust just a few settings in a Simple mode (Figure 11) by default. There are settings that affect Reconstruction Filter and Slew Rate Limit together as a Smoothness setting, and a setting that affects Damping, Friction, and Inertia filters together as Damping setting.
Page 32
Figure 12 Advanced Profiles mode By using Go back to simple mode -button, all advanced mode adjustments are discarded for the current profile, and settings that were last used in the Simple mode take effect again. Profile settings (Simple Mode) Edit profile name Profile name can be changed.
Page 33
Profile settings (Advanced Mode) Profile name Profile name can be changed. Press Enter after editing to apply the new name. Overall strength This slider controls the overall force feedback strength. Steering range Steering range can be adjusted via this setting. Bumpstop feel Bumpstop is a software generated effect that prevents wheel from turning over a certain angle in any event.
Page 34
This effect limits how fast the torque is being changed. “Off” (default setting) means, that the rate of change is unlimited and the rate will be as fast as the Simucube 2 servo drive and motor will be able to accomplish. Limiting the slew rate can be useful to soften the driving feel. If the Driver has experience of other DD wheel systems, limiting the slew rate can be useful to make Simucube 2 feel less active.
Figure 13 Hardware settings tab Hands-off safety feature If the driver lets go of the wheel and the wheel accelerates to fast speed, Simucube by default goes automatically to safe torque mode. When driver’s hands are detected again and produce force against the wheel, the High Torque Mode is smoothly reactivated (if it was active).
Page 36
There is also a beep on torque saturation (clipping), which should be avoided as any additional torque is not felt when torque is clipping. This is useful for VR/HMD users or when the Driver drives a simulator where there is no Force Feedback meter or a clipping detector available. This torque saturation beep can be turned on/off via a checkbox on the Hardware tab.
