USB Interface Board - (Universal Serial Bus Circuit)

NOTE: This item comes fully assembled. No assembly is required.

This USB Interface Board allows for up to 5 input and 8 output channels, all of which are digital. There are also 2 analog inputs and 2 analog outputs with 8-bit resolution.

Expansion is possible by connecting up to a maximum of 4 usb cards to the PC's usb connectors.

A DLL (Dynamic Link Library) is responsible for all of the communication routines. It is possible to write custom applications under Windows 98SE (Second Edition), 2000, ME (Millennium Edition) and XP with C++, Visual Basic, Delphi or any other Windows 32-bit application development too that permits function calls to Dynamic Link Library (DLL) files.

The board featured test buttons to switch between Logic 0 and 1.
