Interrupt Request Settings
To change the IRQ settings on the PC2000, see the bank of switches on the A/D converter. The IRQ may
be changed via the last 3 switches. The following matrix defines the different IRQ settings by switch positions
7, 8, and 9. In the default setting, the IRQ is set to 7. Other combinations for IRQ settings are below. After
you have changed the switches, reinstall the card and change the software settings to match the hardware
settings. (See pages 6-8 for instructions.) The gray block indicates the position of the switch.
