If you are having trouble with your GPIB interface, use the Windows 
Device Manager to troubleshoot your problems. To do so, complete the 
following steps:

1.

Select Start»Settings»Control Panel.

2.

Double-click on the System icon.

3.

Select the Device Manager tab and click on the View devices by type 
button.

4.

Check to see if the interface listing in the Device Manager appears with 
an exclamation point or X by it. If it does, click on the interface listing 
and then click on the Properties button to display the General 
property tab for the interface.

5.

In the Device Status section, look for the status description and status 
code number. Use the status code descriptions and numbers in 
Table D-1 to troubleshoot your problem.

Windows had a problem reading 
information from the GPIB interface. 
This problem can occur if you are using 
an older revision of the AT-GPIB/TNT+ 
or AT-GPIB/TNT (PnP) interface.

Contact National Instruments to upgrade 
your GPIB interface.

The GPIB interface is disabled.

To enable the GPIB interface, check the 
appropriate configuration checkbox in the 
Device Usage section of the General tab.

The GPIB interface is not present, or the 
Device Manager is unaware that the 
GPIB interface is present.

Select the interface in the Device Manager, 
and click on the Remove button. Next, click 
on the Refresh button. At this point, the 
system rescans the installed hardware, and 
the GPIB interface should show up without 
any problems. If the problem persists, contact 
National Instruments.

Windows was unable to assign the GPIB 
interface any resources.

Free up system resources by disabling other 
unnecessary hardware so that enough 
resources are available for the GPIB 
interface.
