3. Make sure you are using a valid DMA channel.
Run the Hardware Diagnostic Test again. When it prompts you for values, enter the
valid base I/O address and interrupt request line as determined in Steps 1 and 2, and
enter the current DMA channel. If the test fails again, one of the following situations
is occurring:
• The DMA channel that you entered when prompted does not match the jumper
setting of the STD-GPIB. Check the jumper setting again.
• Another module or built-in device in your system is using the same DMA
channel. Change the DMA channel of the STD-GPIB and repeat this step using
the new setting.
• The STD-GPIB is installed in an 8-bit only backplane, and DMA is enabled. If
the STD-GPIB is installed in an 8-bit only backplane, DMA must be disabled.
Always select <N> for the DMA channel.
• The module is defective or cannot operate in your system. Complete the
Technical Support Form in Appendix C, Customer Communication, and contact
National Instruments.
Run the Software Diagnostic Test
To verify and test the hardware and software installation, run the Software Diagnostic
Test that came with your NI-488.2 software. The Software Diagnostic Test is a Windows
application that requires no user interaction.
Follow these steps to run the Software Diagnostic Test:
1. Disconnect any GPIB cables.
2. Double-click on the Software Diagnostic Test icon in the NI-488.2 GPIB Software
group in the Program Manager.
If the Software Diagnostic Test completes with no errors, you have installed the NI-488.2
software correctly. If it returns an error message, refer to the next section for
troubleshooting instructions.
