Note: If you are installing the PC/104-GPIB in an 8-bit stack, the only interrupt
lines available to you are 3, 4, 5, 6, 7, or none.
Follow these steps to reconfigure the interrupt request line:
1. Find W1 and W3, the jumpers that set the interrupt request line.
The jumpers are located on the lower edge of your PC/104-GPIB.
Refer to the parts locator diagram, Figure 2-7.
2. Change the jumper settings to configure the PC/104-GPIB to the
interrupt request line Windows 95 assigns or, if you are installing
the PC/104-GPIB in an 8-bit stack, to the line in the range IRQ3 to
IRQ7 you chose on the Resources page of the PC/104-GPIB
Properties dialog box.
To use lines 10, 11, 12, or 15, use the jumper block shown in
Figure 2-9. To use interrupt lines 3, 4, 5, 7, or 9, use the jumper
block shown in Figure 2-10.
3. Record your new settings on the Hardware and Software
Configuration Form in Appendix D, Customer Communication .
