Installation Verification and Troubleshooting

This chapter describes how to verify the hardware and software installation and how to

troubleshoot problems.

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 board does not conflict with anything else in your system.

Follow these steps to run the Hardware Diagnostic Test:

1. Disconnect any GPIB cables.

2. 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. Proceed to the section Run the Software Diagnostic Test, later in this chapter, to

verify the software installation. If the Hardware Diagnostic Test returns an error message,

refer to the next section for troubleshooting instructions.

First verify that all GPIB cables are disconnected and make sure that the switch and jumper

settings on the hardware match the values you entered for the Hardware Diagnostic Test.

The GPIB board normally uses demand-mode DMA. If your computer 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 Appendix B, Changing Software Configuration

Settings, for more information.
