The old PCI-GPIB and PCI-GPIB-300K products from Measurement Computing were marked PCI-488.2 on the silk screen. These boards are now obsolete, but the manufacturer Measurement Computing offers new alternatives, the "PCI-488" board. A USB version called the USB-488 is also available.
The new PCI-488 and USB-488 support the same 488.2 and 488.1 functions as the original PCI-GPIB and PCI-GPIB-300K. Therefore, one should not have to make significant changes to the code - in most cases you will not need any changes to function calls.
However, software written for the old PCI-GPIB and PCM-GPIB will not work with the new PCI-488 and USB-488 without a change of headers and a recompile.
You can test the compatibility of your application with the new libraries without purchasing the new board. You just need to download the libraries from MCC's site and follow the instructions below to see if your application will compile.
You can download GPIB-488 Version 2.0 (the driver and libraries for the PCI-488/USB-488) here :
ftp://ftp.measurementcomputing.com/downloads/GPIB/USB-488%20&%20PCI-488/gpibsetup.exe
Instructions for Migrating Visual Basic Applications to the GPIB-488 2.0 library
--------------------------------------------------------------------------------
After you have installed GPIB-488 Library 2.0, you should find the programming samples and BAS modules you require in the folder:
C:\Documents and Settings\All Users\Documents\GPIB-488\Language Interfaces\VisualBasic\
To migrate your existing VB6 application to the new board, you just need to remove the existing BAS file for the Measurement Computing PCI-GPIB board from the project, and add the two new BAS files provided "GLOBAL.BAS" and "Vbib-32.BAS." If all goes well, your application will still compile and work. However, some 488.1 commands are not supported in the new libraries. If you are affected by this issue it will be apparent on compilation as the functions will not be recognised.
