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
