SIGNAL/RTS APPLICATION NOTES

2 Application Note 6

Base Address, IRQ, and DMA Assignments

The following table shows the base address, IRQ, and DMA assignments for the SIGNAL

analog I/O and DSP boards and other common system components. If an IRQ or DMA entry

is omitted in the table, then that board does not have IRQ or DMA hardware. Note that

commercial programs for detecting address, IRQ, and DMA assignments are not reliable. The

best way to resolve a conflict is to manually construct a similar table for your system,

including all the system components. Note that post-1995 hard disk/CD-ROM drives may

conflict with DT-2821 analog I/O boards.
