3. Board Address Setup
If mounting works in one system that a lot of I/O ports are required, several AIO series boards are
classified according to each board address.
Distribution of each board sets it up through 4 pin DIP switch (SW1). A system is designed of
maximum four boards at the same time so as usable.
SW1 Setup
2 1 ON
OFF
1 2 Board No.
OFF OFF 0

An analog output goes out through D-sub 15 pin connector like Figure 4-1. The eight analog channel
outputs are making it with bases of channel0 ~ channel 7 by AGND. Always AGND and DAC channel
shall be connected outside with pairs.

A common analog GROUND(AGND) works input basis for the SE connection. At this time, the input

ADC CH1/3/5/7
[Figure 5-2. Analog DI (Differential Input) Connection]
An analog DI connection is a difference between two input channel pairs. At this time, the input pairs
connect according (CH0 <-> CH1), (CH2 <-> CH3), (CH4 <-> CH5), (CH6 <-> CH7). So, in case of DI
connection have total 4 input channels.

6. Installation
After unpacking, inspect the board carton to make sure there are no damages on the board.
6.1 Package Content
Product Contents
1. PCI-AIO02 Board
2. CD (Driver/Manual/API/Sample Source etc.)
6.2 Installation Sequence
To install your PCI-AIO01 board in your PC, follow the steps described in the document “How to
install PCI DAQ Board” provided by DAQ System. If the document is missing, you can get it from
www.daqsystem.com. The PCI-AIO02 board is completely Plug & Play. There are no switches or
jumpers to set. Therefore you can install it easily.
- Your OS requirement : Windows 2000 SP4 or Windows XP SP1 above
The PCI-AIO02 connects to PCI Card Port. After that you can show the below picture of “Found
New Hardware Wizard” window.

PCI-AIO02 Users Manual (Rev 0.8)
-13- http://www.daqsystem.com
If new hardware is found, Wizard will ask you to install the corresponding driver. For installation
of the driver, select the item “Install from a list or specific location (Advanced)” and click “Next”
as in the figure.
The driver folder includes a file of “pci_aio02.inf”and “pci_aio02.sys”that it is necessary for
driver installation.
A warning message appears during installation here, press “Continue Anyway”button.
You can show below message window. Process progress as follows.

PCI-AIO02 Users Manual (Rev 0.8)
-14- http://www.daqsystem.com
If the installation is completely finished, you can show below message window.

PCI-AIO02 Users Manual (Rev 0.8)
-15- http://www.daqsystem.com
If the installation is completely finished, you confirm it in the following ways. Do the following
steps to show up the “Device Manager” window. [My Computer -> properties -> Hardware ->
Device Manager -> Multifunction Adaptors -> PCI-AIO02]
If you can see the “PCI-AIO02” at Multifunction Adaptors, the driver installation is to have
been over. (Check the red circle)
Notice : After installation, you should re-boot the system for the proper operation.

7. Sample Program
DAQ system provides a sample program to make the user be familiar with the board operation and
to make the program development easier. You can find the sample program in the CDROM
accompanying with the board. One of the execution file is “PCI_AIO.exe”.
Sample program is provided in source form in order to show the usage of API (Application
Programming Interface) of the board and may be modified for customer’s own usage.
[Figure 7-1. When Sample program “PCI_AIO.exe” is executed]]
To run the sample application program, you need to use API, it is a form of client DLL. To compile
the sample source to make its executable file, you have to use Import Library files and header files.
You can find them in the CDROM. To run the .exe file, the API DLL file (PCI_AIO.DLL) must be in the
same directory with the .exe file or Windows system folder. Another method is to add the directory of
API DLL file to PATH environmental variable.

Reset the ADC function.
(2) „ADC Init‟ Button
Initialize the ADC function.
(3) ADC Differential Input
When the box toggles, get the Differential input.
(4) Select Channel
Write the ADC channels. The PCI-AIO01 channel numbers are from 0 to 7.

(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.

7.4 Select Channel Graph
(1) Average Numbers
It designate the data number that a moving average is applied to 0 ~ 255.
It is not applied to AD data collection by ADC_GetData() function.
(2) Offset
It is an offset to display graph.
As an offset value is added to data collection, it is used if data aren’t marked to a graph.
(3) Divide
It is a division value to display graph.
It marks let the data reduction in case of the data aren’t marked if the collected data is too large.
(4) „Set‟ Button
Set the Average Number, Offset, Divide value.
