Base Address (SW1)
The computer must know the DaqBoards base address. Check the base address setting (3-digit hex) on the
Base Address switch (see figure). The factory default is 300 hex (within the standard range for a prototype
card; see table). If the default value does not work, you must select an address within 200 to 3FF (256 to
1023 decimal). In addition, the address must be on a 4-byte boundary, and it must not conflict with
addresses already in use.
External Analog Expansion Power (JP1)
This 4×2 header (JP1) has 3 possible
settings. If analog option cards (DBKs) are
used, the JP1 pins are set to provide
±15 VDC to the cards. If such cards are
not used, the counter/timer CTR0 is
available, and JP1 must be set accordingly.
The default setting is for use of analog
option cards.

If using a DBK32A Auxiliary Power Supply or a DBK33 Triple-Output Power
Supply Card, the JP1 shunt jumpers must be entirely removed. Placing the
jumpers on -OCTOUT and -OCLKIN will damage the 8254 timer chip.
Refer to the Power Management section in chapter 7, DBK Option Cards and Modules, as needed.
