I have succesfully build the K8096 kit and the stearing of the motor works good with Windows XP & Visual Basic 2011 Express. The issue I face is that I want to detect ,with switches, that the end of the bed has been reached. I saw that input 0 and 1 react without any programming by the PC, it looks like this is in firmware of the board. It runs now by using input 2 and 3.
Could you let me know how I can let VB react on input 1 and 2 instead of the board itself?
The board has a demo mode, in that mode the inputs have an action assigned to them. The action for each input in the demo mode is described in the manual.
You can send the demo off command to leave the demo mode and than you will have control over each input and you can program an action to it yourself.
Use the motordemo program for windows (download from the velleman website) to see the demo toggle in action.
