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.

Run the Hardware Diagnostic Test

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.

Using Single-Cycle DMA

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.
