(8) Select Range

Set up the ADC input range per channel. (0 to 5, ±5, 0 to 10V, ±10V)

(9) Voltage Level Conversion

Change the data to voltage level.

(10) Select Resolution

Set up AD Data width (bit).

The AD converter of board can support three resolution (12, 14, 16bit).

(11) CH0 ~ CH15

In case of PCI-AIO01, it use only CH0 ~ CH7.

7.3 DAC Test

(1) „DAC Reset‟ Button

Reset the DAC function.

(2) „DAC Init‟ Button

Initialize the DAC setup.

(3) Select Channel

Write the DAC channel. The PCI-AIO01 channel number is from 0 to 1.

(4) „DAC Out‟ Button

The range is from 0 to 4095 (Refer to API function DAC_GetData() at chapter 8)

Ex) In case of 0 ~ 10V range setup

If output voltage is 5V, the setup value is (5V/ 10V) * 4096 = 2048.

In case of -10 ~ + 10V range setup

If output voltage is 5V, the setup value is (10+5V/20V) * 4096 = 3072.

If output voltage is -5V, the setup value is (10-5V/20V) * 4096 = 1024.

(5) „Select Range‟ Button

Set up the DAC output range per channel. (+5V, +10V, +10.8V, ±5, ±10V, ±10.8V)

(6) DAC Auto Out

All current DAC value automatically output.
