Re : compatible drivers for 488.2 and 488A

[ornito]

I would like to adress different experiments with a single computer, using Visual Basic. Some old ones use Keithley KUSB-488A, others the more recent NI GPIB-USB-HS (488.2).

While drivers are available for both, the setup of the 488A driver won't let you install this driver, unless you first uninstall the 488.2 one.

Is there a way to use both GPIB interfaces on a single computer, using Visual Basic ?

Hi Ornito,

By looking for information, I saw on a previous support request that the only way to install these drivers is to install them on two different systems ...

What happens if you install 488A and then 488.2 ? Is there any error or warning message ?

Best regards,

Hi,

488.2 driver detects 488A and replaces it, unfortunately.
