Changing the Interrupt Request Settings for the ADC500
To change the IRQ settings on the ADC500 board, see the bank of 4 dip switches labeled SW2. 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 1-4 for instructions.)
The gray block indicates the position of the switch.
