1. GENERAL
Keep the steering wheel away from water and humidity.
Avoid long exposure to direct sunlight to prevent degradation of carbon fiber finish.
Do not try to open your steering wheel.
Do not try to remove the hub from the back of the steering wheel.
Make sure the coiled cable is loose rather than very tight, to ensure the cable lasts longer
and doesn’t get damaged.
All measures are expressed in metric units. You will need metric tools for nuts and bolts.
Rexing GT Steering Wheel requires a powered USB hub for connection to PC.

2. ATTACHING THE WHEEL TO THE BASE OR QUICK RELEASE
Illustration 2: attaching the steering wheel hub to bases or
quick releases that have threads
Use M5 x 10 mm bolts for bases or quick
releases that have threads, for example:
Simucube, Fanatec Podium Hub, NRG or
similar. We recommend to use the supplied
washers.
Necessary tools: 8 mm wrench key
Illustration 3: attaching the steering wheel hub to formula
type bases or quick releases
Use M5 x 16 mm bolts and M5 nuts for bases
or quick releases such as Q1R and most
formula-type quick releases (Lifeline, Go-
Race, Sparco etc.). We recommend to use the
supplied washers both for bolt and for the
nut.
Necessary tools: two 8 mm wrench keys or
one 8 mm wrench key and one 8 mm socket
wrench key.
For quick releases that have 6 holes, it is enough to use only 3 holes.
For Fanatec Podium Hub it is enough to use 3 holes, either on 50,8 or on 70 mm diameter.
The best way to secure the screws is to start them with your fingers, and then tighten them with a
wrench key.
Tip: To avoid damaging the surface and components under and near the hub, we recommend
covering it with some masking tape while inserting and securing the bolts.

3. INSTALLATION TO PC
Rexing GT Steering Wheel requires a powered USB hub for connection to PC. Plug the supplied
coiled USB cable into the wheel on the one end and a powered hub on the other end. The
powered USB hub should be plugged directly into your PC back USB connector.
4. SOFTWARE INSTALLATION
All buttons and encoders are functional as soon as the steering wheel is connected to the PC. To
enable LCD and LED functionality, please follow these instructions:
4.1. Pushbuttons LEDs and RGB LEDs
Use Simdash software to configure your pushbutton and RGB LEDs. Simdash offers a wide variety
of choices to adapt your LEDs to any vehicle or simulation. In order to do this, first install and open
the Simdash app (https://www.symprojects.com/downloads).
Once the wheel is connected to your PC, a green light will appear in the Rexing.eu section within
the "Connected devices" menu. The "Configure" button in the Rexing.eu section opens the
Configuration Screen with the following options in General settings:
General settings:
oImport Settings - opens profiles you previously saved
oExport Settings - enables you to save the current settings as a profile
oClear all Settings - deletes the settings in the current profile
oSpeed Limiter Lights - enables the setup (color and speed of alternating) of the Speed
Limiter Lights
oQuick Config - opens the Shift Lights Wizard (you will be notified that the Quick
Config function will delete the configuration of all the LEDs. It is OK to click Yes here if
you wish to (re)configure your LEDs).

Quick Config allows the configuration of the 11 RPM LEDs by changing their color and other
settings:
oIn order to change an LED's color, just click on a single LED and choose the color.
oIf the "Symmetric" box is not checked, the RPM LEDs will light on from left to right. If it is
checked, the LEDs will light on from left and right, and continue towards the center.
oIn the From/To section you can insert your vehicle's RPM light range in percentage or RPM
value.
Tip: a good start would be to set the RPM to percentage with values from 80% to 97%, and
further adjust it to your wishes.
oIn Shift Point section you can configure the LED settings and set your vehicle's shift point
RPM.

The "Next" button saves your settings from this window and opens a new window, offering to:
oDisable Speed Limiter lights (no Pit Limiter function on the LEDs)
oConfigure LEDs for pit limiter individually (choose the color and blinking speed or no
blinking option for each LED)
oConfigure Alternating Pattern (choose two colors and speed of alternating). The two chosen
colors apply to all 11 RPM LEDs.
The "Create Configuration" button saves the current configuration.
Lights
In the "Lights" section, click on any single RGB LED configure its function or change its color.
Each LED can be configured to any telemetry data, with the possibility to set more conditions to
each LED and to prioritize among them in a desired way. The condition which is higher on the
condition list has the priority over the one(s) below. A condition can also be copied using the
"Copy" image, and then Pasted onto another LED by clicking on Paste button. The light bulb
icon is the test icon, applying the set condition directly to the LED on the steering wheel.
RPM LEDs brightness is adjusted using the brightness potentiometer on the steering wheel.

Buttons' LEDs
In the "Buttons' LEDs" section, click on any single button LED to configure its function. The buttons
LEDs have fixed color. Configuration is done in the same way as for RPM LEDs. The "Buttons' Leds"
section also enables to adjust the brightness of pushbutton LEDs.
EXAMPLE LEDs SETUP
This is an example of a button LED which is always on, but starts blinking when speed limiter is on.
In "Buttons' LEDs" section click on a single LED to configure it. Click on "New", and choose
the "LED always ON" condition, with Blinking set to None. The next condition you set will
come above this condition and will have priority.
Click on "New" again and choose, for example, the condition "Speed limit is ON". Set
Blinking to Normal. This way the LED which is normally on will start blinking when the speed
limiter is on.
Remember to click OK both on the LED configuration screen and on Rexing configuration
screen in order to save your settings.

Games like Assetto corsa, ACC and iRacing don't need any additional configuration or plugins to
work with SimDash.
Some games, like rFactor 2 and F1 2021, will require an additional step in LED configuration:
SimDash will configure the plugin for these games if you go to "Simulations" tab on the main
screen in SimDash (next to "Main"). Then navigate to the simulation you want to use, click
Configure and follow the simple steps after that.
4.2. LCD installation
Firstly, the LCD drivers must be installed. Download them here:
https://www.dropbox.com/s/e7y49pvwk8imbyf/USBD480_installer_win10.exe
The LCD requires an additional app to show data from the game. Choose between:
Simhub https://www.simhubdash.com/download-2/
Z1 https://www.z1simwheel.com/dashboard/index.cfm
SimMonitor from Simdash https://www.symprojects.com/downloads
Joel Real Timing https://joel-real-timing.com/index_en.html
or other USBD480 compatible apps.
Once you choose and install one of these apps, follow their instructions to set them up to output
data to USBD480 display.

Here is a short example of setting up the integrated USBD480 LCD to work with Simhub software:
download Simhub from the link in the section above
open the app and choose "Dash studio" from the menu on the left
choose "USBD480" from the top tabs
check the "Enable display" box
now explore the options and settings to your liking
Tip: In case of screen "flickering", the FPS should be reduced from 60 FPS (default) to a lower value
until the flickering stops (values between 45 and 20 should work).
For Simhub go to "Dash Studio" > USBD480 tab > and set "Display refresh rate limit (FPS)"
For Z1 go to "Z1 Dashboard Settings" > General tab > "FPS target"

4.2.1. Games that output data using UDP (e.g. F1 2020, F1 2021)
UDP data can be received by only one application at same time. This means you would be able to
use eiter LCD via Simhub or LEDs via SimDash, but not both at the same time. To get around this
limitation, SimHub offers you to "forward" the UDP data to another port and/or computer.
To enable UDP forwarding simply go into the game settings in Simhub to choose the port and
enable it for the games you may want :
Make sure to use another udp
port for forwarding (for instance
simhub receives on 20777 and
forward data to 20778). You
must then configure the other
app to receive data on this port.
In Simdash go to "Simulators" tab, find your
game and click on "Configure". If this is the
game that sends data via UDP, you'll see the
option to change port number. Now modify
the port number to the one you added for
port forwarding in Simhub (in this example
20778).

5. USING TOGGLE SWITCH AND 8-POSITION "EXTRA SWITCH"
Toggle switch is connected to the 8-position "Extra switch". It provides 8 different, selectable,
configurable positions. If the 8-position switch is turned to position 1, nothing will happen until
toggle switch is pulled. When you pull the toggle switch, it will be read as button press for switch
position 1. Position 2 will have different button press, etc.
This is convenient for mappings that have several different states, like TC, ABS, driving aids and
similar.
To map it in games:
turn the "extra switch" to position you want to use
select the game function you want it to be assigned to
once the game asks for button press - pull the toggle switch
