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.
