Chapter 4 Installation Verification and Troubleshooting

Correcting Hardware Settings

Follow these steps to troubleshoot Hardware Diagnostic Test error messages.

1. Make sure you are using a valid base I/O address.

Run the Hardware Diagnostic Test again. When it prompts you for values, enter

your base I/O address, but enter <N> for both the interrupt request line and the DMA

channel. If the test fails again, one of the following situations is occurring:

• The base address that you entered when prompted does not match the switch

settings of the STD-GPIB. Check the switch settings again.

• Another module or built-in device in your system is using the same address

space. Change the base I/O address of your STD-GPIB and repeat this step

using the new setting.

• The module is defective or cannot operate in your system. Complete the

Technical Support Form in Appendix C, Customer Communication, and contact

National Instruments.

2. Make sure you are using a valid interrupt request line.

Run the Hardware Diagnostic Test again. When it prompts you for values, enter the

valid base I/O address as determined in Step 1, the interrupt request line, and <N>

for the DMA channel. If the test fails, one of the following situations is occurring:

• The interrupt request line that you entered when prompted does not match the

jumper setting of the STD-GPIB. Check the jumper setting again. If you are

using a computer not manufactured by either Ziatech or WinSystems, refer to

Appendix B, Interrupt Routing, for proper interrupt jumper settings.

• Another module or built-in device in your system is using the same interrupt

request line. Change the interrupt request line of the STD-GPIB and repeat this

step using the new setting.

• The module is defective or cannot operate in your system. Complete the

Technical Support Form in Appendix C, Customer Communication, and contact
