Here is a document showing USB and parallel port interface timings

The installation contains one file, an installer (msi) file plus a setup.exe. Once installed consult the quick start guide. If you install an update don’t forget to reset the hardware configuration.

There is also a test build on the downloads page - it’s my latest “work in progress” - it includes an automation interface so you can drive it from an external program and a custom hardware interface to use it with modified hardware.

The program is protected by a product key / activation process.
