VM140 - A prototype card of a usb interface

Description

Port in / out card with optoisolation.
The I / O card contains 33 digital and analog input and output ports. The connection to the computer is opto-insulated, which protects the PC against damage.
All communication procedures have been developed in the form of Dynamic Link Library (DLL) libraries. The system works under Windows (98SE, 2000, Me, XP) and allows you to use Delphi, Visual Basic, C ++ Builder and other applications.
