Base I/O Address and Interrupt Selection
To change base I/O address or interrupt selection, refer to the NI-DAQ
Configuration Utility Help file. You can configure the PC-DIO-24PnP
to use base addresses in the range of 100 to 3E0 hex. Each board
occupies 32 bytes of address space and must be located on a 32-byte
boundary. Therefore, valid addresses include 100, 120, 140…, 3E0 hex.
The PC-DIO-24PnP can use interrupt channel 3, 4, 5, 7, or 9.
Note: To configure the non-Plug and Play PC-DIO-24 board, refer to
