Switches and Jumpers
To ensure that the desired mode of operation is obtained, the ISA-type DaqBoards must be configured.
This is accomplished via on-board jumpers and a DIP-switch. Although the configuration of all four
DaqBoard-ISA models is similar, jumper locations differ, as can be seen in the following figures.

Location of DaqBoard Jumpers
The following DIP-switch and jumpers must be properly set to ensure the desired mode of operation:
• SW1 - Base Address
• JP1 - External Analog Expansion Power
• JP2 - DAC Voltage Reference Header
• JP7 –Reserved for factory use.
• JP8 - Interrupt & DMA
Base Address (SW1)
The computer must know the DaqBoard’s base address. Check the base address setting (3-digit hex) on
SW1, the Base Address switch. 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.
