sensing an external switch closure from a PC program


NormanHutchison

Hi team,

I'm looking to design a system to run on a PC and take some action when an operator presses a foot-switch (one contact closure). I've looked at an Ethernet to digital I/O adaptor (RS 789-8135), but that seems like overkill. Can anyone suggest a solution ? (I'm hoping to use Powershell on the PC for processing)
