ni -pnp

 excludes that I/O port from future testing.  If you know that you do not have

any National Instruments Plug and Play modules in your system, you can configure

ni -pnp

 so that it does not attempt to detect any Plug and Play modules.  

ni-pnp

prompts you to choose between entering the fail-safe mode or disabling the detection of
Plug and Play modules.

To verify and test the hardware installation, run the Hardware Diagnostic Test that came
with your NI-488.2 software.  The test verifies that your hardware is functioning properly
and that the configuration of your STD-GPIB does not conflict with anything else in your
system.

To run the test, double-click on the  Hardware Diagnostic Test icon in the NI-488.2
GPIB Software group in the Program Manager .

If the Hardware Diagnostic Test completes with no errors, your hardware is functioning
properly.  If it returns an error message, refer to the next section for troubleshooting
instructions.

First verify that the switch and jumper settings on the hardware match the values you
entered in the Hardware Diagnostic Test.

The STD-GPIB normally uses demand-mode DMA.  If your system cannot use demand-
mode DMA, the Hardware Diagnostic Test prints a message telling you to use single-
cycle DMA.  You can select single-cycle DMA by configuring the software using the
GPIB software configuration utility.  Refer to the Configure the Software  section of
Chapter 3, Software Installation and Configuration,  for information.
