Is there anyway to capture IEEE 488.1 commands sent over a GPIB card on a 286?

[Nasty Nate]

We have a legacy system in our lab that runs on a older 286 PC. The operating system is MS-DOS. The software that communicates to the instruments was obviously written a long time ago, and apparently the drivers for the GPIB card are 'built in' to the software (I'm not even 100% sure that the card is an NI card). I am trying to write the replacement software for this system since. My question is, is there any program (or hardware) out there that will run on a 286 and allow me to capture the commands sent on the GPIB bus? NI Spy would be perfect, but I doubt it runs on a 286.

Thanks

What about a GPIB analyzer that you can plug into a separate pc. NI sells pci and pcmcia versions. Info on these can be found at https://www.ni.com/en-us/shop/category/gpib-serial-and-ethernet.html?productId=118313.

I too would recommend an external analyzer as Dennis suggests. You should be able to rent a GPIB analyzer from a test equipment rental company if you don't want to buy one.

If the old DOS GPIB software is operating with NI GPIB driver, there may be a traffic monitor software IBMON that is included in the NI-488 MS-DOS software installed on the target 286 PC.  The monitor software is a TSR program that hooks up the GPIB DOS calls and shows their logs.  If not using NI GPIB software/hardware, you should use external GPIB bus analyzer as other guys are saying.

To check if your software is running with NI GPIB, check the CONFIG.SYS file of the PC.  If it includes DEVICE=C:\GPIB.COM line, possibly the GPIB is from NI.
