HPIB was the fore runner to GPIB. HP developed the protocol for instrumentation communication, which became an IEEE standard and GPIB was the generic version. GPIB stands for general purpose interface bus. It is used typically to hook more than one instrument/printer/PC together for control and data transfer. My 4th year thesis dealt with Pc communication to an HP data aquisition box over this bus/protocol configuration. I believe I used a general intruments GPIB card for the PC. Does that help? Mike
