The CIFX WinAC Driver offers transparent access to Hilscher CIFX devices. The driver functionality is located in the CIFXWinACDriver.RTDLL (CCX Software) which is called from the WinLC scan cycle via the WinAC ODK calling interface (SFB). Hardware access to the Hilscher hardware (Optional Third-Party Device) is based on the Hilscher CIFX RTX Driver for IntervalZero RTX (CIFXRTXDrv.rtdll). Necessary hardware configuration, firmware and configuration file settings are downloaded by the Hilscher CIFX Driver for Windows and stored in the Windows "Registry" and "Program File" directory. This information is used by the CIFX RTX Driver to get the Hilscher hardware into operation.
