National Instruments 321042A-01 Manual De Usuario

The five STD bus interrupts are INTRQ* (P44), INTRQ1* (P37), INTRQ2* (P50),
INTRQ3* (E67), and INTRQ4* (P6).  All five interrupts are supported in an
STD32 backplane and all but INTRQ3* are supported in an STD-80 backplane.
These interrupts are all active-low signals.

The interrupt routing for the STD-GPIB is shown in Table B-2.

If you want to use a frontplane interrupt, refer to Table B-1, then Table B-2, to
determine the correct jumper settings for the interrupt level you want to use.  For
example, if you want to configure the STD-GPIB to use IRQ10, and you find out
that IRQ10 is connected to the frontplane interrupt connector pin 6 of your
computer, then you would refer to Table B-1 for the associated signal, FP6.
Table B-2 shows that for interrupt source FP6, you should install the jumper as you
would for a WinSystems IRQ12 or Ziatech IRQ11.

If you want to use a backplane interrupt, refer to Table B-2 for the correct jumper
settings.  For example, if you are configuring the STD-GPIB to use IRQ9 on the
INTRQ* line in your computer, you should install the jumper as you would for a
WinSystems IRQ7 or Ziatech IRQ9.
