GPIB device found but no reognized

[ACar89]

Hello

On a remote system, I have HP 3458A and Lake Shore 331 Temperature control connected on GPIB. I have installed a NI PCI-6259 on the remote system, as well as NI VISA 4.2 and Real-time 11. Also, I have installed the instrument drivers of the two devices on my local computer.

Using VISAIC, I am able to see both devices however, I am only able to use the HP 3458A. The GPIB address of the LS 331 is incomplete; it is visa://[IP]/GPIB0::INTFC while the HP 3458A is visa://[IP]/GPIB0::22:INSTR

Any ideas?

Thanks in advance

You mentioned the LS is a GPIB device. Try installing NI 488.2 and see if it shows up.

Hello

I have installed NI 488.2 version 2.5 on the system. I just forgot to mention it.

Thanks though,

Have you tried to run a *idn command to the LS device? You also may try to run an example program in LabVIEW to see if you can communicate.

It sounds like your seeing the controller and the DMM.

do you have the 331 set to use the GPIB? that must be done from the front panel.

I had tried running the *idn to the device and I am not sure what the 331 set is. However, it turned out that the GPIB cable going to the device I was trying to communicate with was damage (not exactly sure how) and it started communicating when I attempted to use a different GPIB cable.

All is good. Thank you for your time.
