Hello,
To determine if your device is comatible with 488.2, you will need consult your instrument's documentation.
The correct way to find an instrument is to right-click on your GPIB card in Measurement and Automation Explorer (MAX) and select Scan for Instruments. If you are still timing out from here, make sure the instrument is turned on. You might also try using a different instrument to determine if the problem is with your GPIB Card.
Let me know if this does not work.
