PC/104-GPIB for Windows 95

Single-Cycle DMA Required

This error occurs if the Diagnostic utility detects that it is unable to 
perform demand-mode DMA for the PC/104-GPIB and that the GPIB 
software has not been configured to use single-cycle DMA. If you 
encounter this error, you should use the Device Manager to configure 
the GPIB software to use single-cycle DMA for all DMA transfers, and 
then run the Diagnostic utility again.

To configure the GPIB software to use single-cycle DMA for the 
PC/104-GPIB, complete the following steps:

1.

Double-click on the System icon under Start»Settings»Control 
Panel. 

2.

In the System Properties dialog box that appears, select the Device 
Manager tab.

3.

Click on the View devices by type button at the top of the Device 
Manager page.

4.

Double-click on the National Instruments GPIB Interfaces icon.

5.

Double-click on the interface to be configured. 

6.

Select the GPIB Settings tab.

7.

Click on the Advanced button and make sure that the Demand 
Mode DMA item is unchecked. 

GPIB Software Problem Encountered

This error occurs if the Diagnostic utility detects that it is unable to 
communicate correctly with the GPIB hardware using the installed 
GPIB software. If you encounter this error, shut down your system, 
restart it, and run the Diagnostic utility again. If the problem persists, 
try reinstalling the GPIB software for Windows 95.

Unknown Problem Encountered

This error occurs if an unknown problem is encountered while trying to 
execute the Diagnostic utility. If you encounter this problem, shut down 
your system, restart it, and run the Diagnostic utility again. If the 
problem persists, try reinstalling the GPIB software for Windows 95.
