Switches and Jumpers

The configuration of all 4 DaqBoard models is similar except for jumper locations. (Refer to the diagram
that matches your model.) The internal configuration of each DaqBoard model consists of setting the
following switches and jumpers for the desired mode of operation:

SW1 - Base Address

JP1 - External Analog Expansion Power

JP2 - DAC Voltage Reference Header

JP7 - Calibration (refer to

Calibration

).

JP8 - Interrupt & DMA
