Interrupt Selection
The GPIB-PCII/IIA interface board can use any of six interrupt lines available
on the PC, or no interrupts at all. The interrupt line is selected using the jumper
sets labeled IRQ2 through IRQ7 (see Figure C-1). The GPIB-PCII/IIA is set at
the factory to use line 7. To select another interrupt line, place the supplied
jumper across the two pins adjacent to the label designating that interrupt line.
Figure C-5 shows the selection of interrupt line 7.
