Select the DMA channel line required by placing the pair
of jumpers across the appropriate pins. If in doubt leave in the
jumpers in the factory set condition, DMA 1.
D/A Output Range Selection.
_________________________
Both DAC0 and DAC1 may be independently set for a
variety of output voltage ranges. Five jumpers for each DAC are
used to configure the output range. The DAC1 jumpers are
labelled DAC1 and are found at the extreme top left hand side
of the AD1200 card. The DAC0 jumpers are labelled DAC0 and
are found at the top left hand side of the Ad1200 card, between
the DAC1 and ADC converter jumpers. One pair of jumpers
labelled BP and UNI determine whether the output range is
bipolar or unipolar, the other 3 jumpers labelled ABC determine
the voltage span.
Remember: Calibration should be performed when output ranges
are changed, to ensure the AD1200 remains in specification and
measurements are traceable back to recognised standards.
