Firmware Version Information

General
Flashing the CPX firmware currently requires Windows and Microsoft .Net framework in order to run the application necessary. Microsoft .Net can be obtained here: https://www.microsoft.com/net/download
There are two versions of the adapter: CPX V1 and CPX V2. CPX V1 will not have any version designations on the label. V2 will either have "Version 2" on the label or "V2" on the back. The only change between V1 and V2 adapters was the ability for the V2 adapter to sense the voltage from the wheel and determine when it is connected or turned on. The helps facilitate pedal range initialization on the wheel.

CPX Panel Application

Current Version: 1.2
The CPX Panel application is used for troubleshooting (through support) and for flashing new firmware to your CPX adapter. The application was written by me and is safe. If your browser, anti-virus or Windows complain about the application, please allow it to run. As part of the firmware update process, the application will connect to my website in order to obtain the newest firmware versions. Thus, you must have an internet connection and allow the application access in order to obtain the firmware and flash your adapter.
