Figure C-5. Default Interrupt Jumper Setting for GPIB-PCII Mode
If you do not want to use interrupts, you must logically disconnect the GPIB-
PCII/IIA from the IRQ lines by selecting
NONE
for the interrupt line when you
run the software configuration program, as explained in Step 3. Configure the
Software, later in this appendix. The board can remain in the backplane and no
jumpers have to be moved or changed.
Shared Interrupts in GPIB-PCIIA Mode
Multiple GPIB-PCII/IIA boards can share the same interrupt level if they are all
configured for GPIB-PCIIA mode.
If you use the GPIB-PCII/IIA in GPIB-PCIIA mode and you want to change the
interrupt line, you must set switches I0, I1, and I2 in switch block U2 to the line
setting in addition to setting the interrupt jumpers.
