VIsion is short for Vincent's Instrumentation Solution. It's a collection of Visual Basic code libraries that allow you to control various equipment such as Multimeters ,scopes , power supplies over the GPIB bus.

Vision 5 Seamlessly integrates with Visual Basic 5.0 or Later. the whole package is supplied as Sourcecode that is just loaded ito your projects. The GPIB kernel is contained in a single Module. All you do is Add this to your project and you're set. Just Call GPIBinit in your main programs startup routine.

Instrument libraries come in 2 flavors : As modules (.BAS files) or as Class objects   Whatever flavor you want to use.

The Classes can be linked to Graphical user interfaces that are loaded as custom controls ( Source supplied for all of them )

Besides that it also allows you hardware access to things such as printerports and other ports. the GPIBcore has also a set of routines to do 'bit-twiddling' on binary numbers.

The package allows you even to control instruments over a TCP/IP link. that's right you can control GPIB instruments via the internet anywhere in the world. Just give the IP address and you're done.
