GPIB-USB-HS found in NI MAX, but no instruments found?

[neets]

am using Windows 7 on a PC, just installed NI-488.2 for brand new GPIB-USB-HS. I have the GPIB-USB-HS connected to an Agilent E4419B power meter.

 in NI MAX, i can see the GPIB-USB-HS just fine.

However, when i scan for instruments it says "no instruments found." it doesn't find the power meter at all. even though i have it connected to the Agilent power meter...it is definitely connected. The address of the power meter is 18 as it has always been.

the GPIB USB HS has amber "ready" sign. it never lights up the "active" LED.

I have set the remote interface settings in the power meter to GPIB, etc..i don't think it's anything with the power meter as i just used this with a different GPIB-USB-HS the other day (used labview) and had no problems at all.

Hi Neets,

I actually just had a customer with a very similar issue this week, and we were able to get everything back up and running by enabling the VISA passport editor so that the Agilent hardware can be configured in MAX. It sounds like your hardware is getting picked up, but I think it just hasn't been configured properly. This could be why it is not appearing as expected in MAX. Here are two Knowledge Bases that discuss using NI GPIB communication with Agilent hardware and how to set up a GPIB-USB converter:

The first KB discusses enabling the VISA passport editor, which will allow you to configure Agilent hardware and recognize it in MAX. The second KB goes through renaming the aliases for your instruments. Hopefully these will get you back on track.

Tulip support is for Agilent GPIB controllers - not instruments.

Also, your links do not work.

Sorry about that. Here are the links again:

Though the first link may not be useful since you are indeed using an instrument instead of a controller, the second link may be useful to make sure that you have configured everything with your GPIB-USB-HS correctly.
