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).

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.
