Is there some kind of .NET SDK for this product?
At the moment there is no .NET SDK available.
You can use a normal Windows DLL in the .NET application too.
Here's the link to download a Visual Basic 2008 Express example project for the PCS10 / K8047: http://www.box.net/shared/t5se5yp5s6
The needed files (latest version) K8047D.DLL, FASTTime32.dll and K8047E.EXE are located in the folder: \K8047DemoVB_2008_64-bit\bin\x86\Debug\
This demo can be run also in a 64-bit operating system.
The K8047D.DLL is standard Windows DLL, you cannot reference it.
