3-7
To use your DDA-08/16 with DriverLINX or any application program
that requires a configuration file, you must indicate the board number,
board type, base address, interrupt level, and analog output range in a
configuration file.
Table 3-1 lists the items that are configurable for DDA-08/16 boards, the
available options, and the default settings in the configuration file. Be sure
to make note of the configuration of all switches and jumpers on the
board. You will use this information to enter the correct configuration
parameters using DriverLINX. Also locate any information or notes about
the interrupt and DMA channels used by the other hardware devices in
your computer system.

The default base address for board 0 is 300h. If you are using multiple DDA-08/16 boards, the
default base address for board 1 is 308h, the default base address for board 2 is 310h, and the
