I have NI 488.2 (driver 19.5) USB-GPIB control card connecting a Keysight 6654A power supply to a PC (win7 64bit).
Under the Keysight IO expert, the power supply is displayed as "Unknown GPIB0::5::INSTR", and cannot communicate to the PC with softweare of any kind. The NI VISA is set to the primary. I have other instruments on the same bench, like N9010, E8257D, E4419B, they are all working correctly.
Could anyone give any advices?
Thank you Tardz. I did exactly what you suggested, and it is still not working. Here is the snapshot of what I have with different softwares.
Fig1. the Keysight IO Suites cannot display the instrument identity (address 5), which is the 6654A power supply
Fig2. The Device Manager shows the NI 488 driver version is indeed of 17.6
Fig3. The Kesight Interactive IO shows the response to the query commads *IDN? and VOLT?, both return nothing, but status byte (STB) 0x30 which I dont understand its meaning.
Fig4. The Kesysight Command Expert shows responses to the query commands, which are error again.
Do you have any idea about that?
Hi,
GPIB-USB is not supported by driver version 19.5. You must use version 17.6 or earlier, this is documented on the NI website. I have a 6642A and I had the same problem, and I solved it using version 17.6. Here is the link for this download. Your 6654A should work fine after this fix.
ni-488-2 driver 17.6
