I have an old instrument (magnetometer) with an old computer used for control and DAQ. The instrument is in very good shape, but the computer is very old (early 90s) and uses a proprietary software to communicate with the instrument via GPIB. I would like to replace the computer with a new one and write my own DAQ program in LabVIEW, but I do not have the manual of the instrument and do not know the GPIB commands.
Is there any way I can connect another computer to the GPIB interface and 'record' the commands used by the DAQ software from the old computer while the program is running?
I read a little bit about NI I/O Trace (formerly NI Spy), but I am not sure if that can work. When I connect two PCs to the instrument, there seems to be some conflict between the two GPIB cards connected to it, I can only 'see' it from one computer.
Thanks!
