2.2.4 Physical ID of DIP Switch
DID1: Set physical ID number. When the PC is installed more than one PCI8002A , you can use the DIP switch to set a
physical ID number for each board, which makes it very convenient for users to distinguish and visit each board in the
progress of the hardware configuration and software programming. The following four-bit numbers are expressed by
the binary system: When DIP switch points to "ON", that means "1", and when it points to the other side, that means
"0." As they are shown in the following diagrams: "ID3" is the high bit."ID0" is the low bit, and the black part in the
diagram represents the location of the switch. (Test softwares of the company often use the logic ID management
equipments and at this moment the physical ID DIP switch is invalid. If you want to use more than one device that are
the same type in the same system at the same time, please use the physical ID as much as possible. As for the
differences between logic ID and physical ID, please refer to the function explanations of "CreateDevice" and
"CreateDeviceEx" of The Prototype Explanation of Device Object Management Function in PCI8002AS software
specification).

3.10 Methods of Realizing the Multi-card Synchronization
Three methods can realize the synchronization for the PCI8002A, the first method is using the cascade master-slave
card, the second one is using the common external trigger, and the last one is using the common external clock.
When using master-slave cascade card programs, the master card generally uses the internal clock source model, while
the slave card uses the external clock source mode. After the master card and the slave card are initialized according to
the corresponding clock source mode. At first, start all the slave cards, as the main card has not been activated and there
is no output clock signal, so the slave card enters the wait state until the main card was activated. At this moment, the
multi-card synchronization has been realized. When you need to sample more than channels of a card, you could
consider using the multi-card cascaded model to expand the number of channels.

When using the common external trigger, please make sure all parameters of different PCI8002A are the same. At first,
configure hardware parameters, and use analog or digital signal triggering (ATR or DTR), then connect the signal that
will be sampled by PCI8002A, input triggering signal from ART pin or DTR pin, then click “Start” button, at this time,
PCI8002A does not sample any signal but waits for external trigger signal. When each module is waiting for external
trigger signal, use the common external trigger signal to startup modules, at last, we can realize synchronization data
acquisition in this way. See the following figure:

Chapter 4 The Instruction Trigger Function
4.1 Internal Trigger Mode
When A/D is in the initialization, if the hardware parameter ADPara.TriggerMode = PCI8002A_TRIGMODE_SOFT,
we can achieve the internal trigger acquisition. In this function, when calling the StartDeviceProAD function, it will
generate A/D start pulse, A/D immediately access to the conversion process and not wait for the conditions of any other
external hardware. It also can be interpreted as the software trigger.
As for the specific process, please see the figure below, the cycle of the A/D work pulse is decided by the sampling
frequency.

Convert Pulse

pulse after the A/D

Figure 5.1 Internal Trigger Mode
4.2 External Trigger Mode
When A/D is in the initialization, if the hardware parameter ADPara.TriggerMode = PCI8002A_TRIGMODE_DELAY
or ADPara.TriggerMode-PCI8002A_TRIGMODE_MIDL, we can achieve the external trigger acquisition. In this
function, when calling the StartDeviceProAD function, A/D will not immediately access to the conversion process but
wait for the external trigger source signals accord with the condition, then start converting the data. It also can be
interpreted as the hardware trigger. Trigger source includes the DTR (Digital Trigger Source) and ATR (Analog Trigger
Source)
The trigger modes include the edge trigger and level trigger.
4.3 Analog Trigger Function
When ADPara.TriggerDir = PCI8002A_TRIGDIR_NEGATIVE, it is falling edge trigger. The A/D will begin to work
whenever a falling edge occurs on analog trigger signal. The A/D stops when finish a specified length of data sampled
and wait for the next trigger signal.
When ADPara.TriggerDir = PCI8002A_TRIGDIR_POSITIVE, it is rising edge trigger. The A/D will begin to work
whenever a rising edge occurs on analog trigger signal. The A/D stops when finish a specified length of data sampled

and wait for the next trigger signal.
When ADPara.TriggerDir = PCI8002A_TRIGDIR_NEGAT_POSIT, it is either rising or falling edge trigger mode. The
A/D will begin to work whenever a rising edge or falling edge occurs on analog trigger signal. The A/D stops when
finish a specified length of data sampled and wait for the next trigger signal.

Chapter 5 Methods of Using Internal and External Clock Function
5.1 Internal Clock Function
Internal Clock Function refers to the use of on-board clock oscillator and the clock signals which are produced by the
user-specified frequency to trigger the A/D conversion regularly. To use the clock function, the hardware parameters
ADPara.ClockSource = PCI8002A _CLOCKSRC_IN should be installed in the software. The frequency of the clock in
the software depends on the hardware parameters ADPara.Frequency. For example, if Frequency = 100000, that means
A/D work frequency is 100000Hz (that is, 100 KHz, 10uS/point).
5.2 External Clock Function
External Clock Function refers to the use of the outside clock signals to trigger the A/D conversion regularly. The clock
signals are provide by the INCLK pin of J1.
The external clock can be provided by another PCI8002A’s clock output
as well as other device such as clock frequency generators. To use the external clock function, set the hardware
parameters ADPara.ClockSource = PCI8002A_CLOCKSRC_OUT. The A/D sample rate depends on the external clock
frequency.
5.3 A/D Data Bit High Bit Control
Analog input’s data bit is D0~D11, D12 bit is over range flag, D15 bit is trigger flag, D13 and D14 are used to show the
digital input/output status.

Products Rapid Installation and Self-check
Rapid Installation
Product-driven procedure is the operating system adaptive installation mode. After inserting the disc, you can select the
appropriate board type on the pop-up interface, click the button【driver installation】; or select CD-ROM drive in
Resource Explorer, locate the product catalog and enter into the APP folder, and implement Setup.exe file. After the
installation, pop-up CD-ROM, shut off your computer, insert the PCI card. If it is a USB product, it can be directly
inserted into the device. When the system prompts that it finds a new hardware, you do not specify a drive path, the
operating system can automatically look up it from the system directory, and then you can complete the installation.
Self-check
At this moment, there should be installation information of the installed device in the Device Manager (when the
device does not work, you can check this item.). Open "Start -> Programs -> ART Demonstration Monitoring and
Control System -> Corresponding Board -> Advanced Testing Presentation System", the program is a standard testing
procedure. Based on the specification of Pin definition, connect the signal acquisition data and test whether AD is
normal or not. Connect the input pins to the corresponding output pins and use the testing procedure to test whether the
switch is normal or not.
Delete Wrong Installation
When you select the wrong drive, or viruses lead to driver error, you can carry out the following operations: In
Resource Explorer, open CD-ROM drive, run Others-> SUPPORT-> PCI.bat procedures, and delete the hardware
information that relevant to our boards, and then carry out the process of section I all over again, we can complete the
new installation.
