Load Cronus PRO and go to Tools > Options > Device
Set the Output Protocol to AUTOMATIC. (IMPORTANT - If not set to AUTOMATIC then the controller will disconnect every 10 minutes).
These are also the recommended default Speed Up Settings for Logitech and Supported Wheels. Rumble Over Bluetooth is disabled as it's not being used.
Note: Make sure 'Inframe In' is disabled as there have been reports that it causes wheels to randomly disconnect if it is enabled.
Select the CMax Plus Tab and make sure the box to the left of 'Enable PS4 partial crossover support (auto reconnect every 10 min)' is NOT checked.
We also recommend you select the 'Mimic Controller Player LEDs' option if you have CronusMAX PLUS v3 device. This is especially useful if you plan on using our GamePacks.
You can now close the Options window and disconnect your CronusMAX PLUS from your PC.
Your CronusMAX PLUS must be in PS4 Wheel Edition Mode. Go to Tools > Cronus Operational Mode and select PS4 Wheel Edition. Or you can click on the Mode in the Status Bar to bring up the Cronus Operational Mode Wizard.
After setting the Operational Mode, the Cronus PRO Status Bar will look like this.
Some USB Hubs prefer the Cross Over controller to be on Port 3, just make sure that when you power cycle the console that the CronusMAX PLUS completely shuts down (No LED) and doesn't sit in standby mode (Spinning Animation LED), otherwise on reboot the authorization won't work correctly. Note: To correctly shut down the console, usb hub and CronusMAX PLUS, power cycles must be done from the console, not the controller.
The DS4 Authentication controller will be disabled. The lightbar will not illuminate, it will not vibrate and none of it's controls will interefere with your experience. It can safely be left sitting idle on a surface as if it was turned off. Never power on the console with the DS4 controller by pressing the PS button. Only power on the console using the console power button.
You should make sure that the DS4 wireless constroller is un-paired/de-synced from the PS4 for optimum performance. You can do this by connecting your DS4 to the PS4 via your CronusMAX with a USB cable and go to Settings > Devices > Bluetooth Devices > then click on the controller you're using (the green lit-up one) > Disconnect.
If the LED on the CronusMAX PLUS does not change from AU to a number then the authorization controller is not authenticating. 99% of the time this means either you didn't set the Output Protocol to AUTOMATIC in Step 1 of the instructions, or the Micro-USB cable to the DS4 controller is faulty or simply not compatible, you should try another one. Another issue that sometimes comes up is that the controller USB port has a loose data pin. It will charge fine, but won't transmit data.
If you find that the controller disconnects at random times, and you are sure everything is setup correctly and Inframe In is disabled in your Speed Up Settings, then the USB cable is obviousley losing its connection between the DS4 authorization controller and the CronusMAX. This can be caused by a poor quality USB cable, the USB socket on the DS4 authorization controller itself is loose, or the USB hub you are using is poor quality. Check all connections and replace any parts if necessary.
