1. Introduction
The PCI-1002LU/HU and PEX-1002LU/HU cards are the new generation product that ICP DAS
provides to meet RoHS compliance requirement and is designed as completely compatible with the
PCI-1002L/H. Users can replace the PCI-1002L/H by the PCI-1002LU/HU and PEX-1002LU/HU directly
without software/driver modification.
The PCI-1002L/H supports 5 V PCI bus and PCI-1002LU/HU supports 3.3 V/5 V PCI bus, while the
PEX-1002L/H supports PCI Express bus. The PCI-1002 series is a family of AD board and features
low-gain 110 kS/s or high-gain 44 kS/s analog input. It provides 12-bit 32 single-ended analog input
channels or 16 differential analog input channels, 16 digital input channel and 16 digital output
channel.
The PCI-1002LU/HU and PEX-1002L/U provide pull-high/low jumpers allow user to predefine the DI
status instead of floating when the DI channels are unconnected or broken. The PEX-1002L/H adds a
Card ID switch for users to recognize the board by the ID via software when using two or more
PEX-1002L/H cards in one computer.
PCI-1002LU/HU (Universal PCI version) and PEX-1002L/H (PCI Express) is fully compatible with the
PCI-1002L/H (PCI version). PCI-1002LU/HU and PEX-1002L/H (new version) sell now; PCI-1002L/H
(old version) will be phase out.
These cards support various OS such as Linux, DOS, 32/64-bit Windows 10/8/7/2008/2003/XP. DLL
and Active X control together with various language sample program base on Turbo C++, Borland
c++, Microsoft C++, Visual C++, Borland Delphi, Borland C++ Builder, Visual Basic, C#.NET, Visual
Basic.NET and LabVIEW are provided in order to help users to quickly and easily develop their own
applications.

2.7 AD Input Signal Connection
The PCI-1002 series card can measure either single-ended or differential-type analog input signals.
The user must decide which mode is most suitable for measurement purposes. Please refer to the
Section 2.2 “JP1: AD Input Type Selection”to see how to configure the JP1 jumper based on your
analog input type.
In general, there are four different analog signal connection methods, as shown in Figure 2-3 to
Figure 2-7. The connection shown in Figure 2-3 is suitable for grounded analog input signals. The
connection shown in Figure 2-4 is used to measure more channels than that shown in Figure 2-3,
but is only suitable for large analog input signals. The connection shown in Figure 2-5 is suitable for
thermocouple connections and the connection shown in Figure 2-6 is suitable for floating analog
input signals.
Note: In Figure 2-5, the maximum common mode voltage between the analog input source and the
AGND is 70 V
p-p
, so the user must ensure that the input signals is within this specification. If the
common mode voltage is above 70 V
p-p
, the input multiplexer will be permanently damaged!
The simplest way to select your input signal connection configuration is listed b elow.
1. Grounding source input signal see Figure 2-3
2. Thermocouple input signal see Figure 2-5
3. Floating source input signal see Figure 2-6
4. If Vin > 0.1 V, gain<=10 and more channels are needed see Figure 2-4
5. Current source input signal see Figure 2-7
If you are unsure of the characteristics of your input signal, follow these test steps:
Step1: Try and record the measurement results when using Figure 2-3.
Step2: Try and record the measurement results when using Figure 2-6.
Step3: Try and record the measurement results when using Figure 2-4.
Step4: Compare the three results and select the best one.

6.2.1 Section1
Although there are 128 I/O ports used by the on-board PCI interface controller, only one register is
used in real applications!! Users should keep the other registers from being modified! The PCI
interrupt control register (4Ch) controls the interrupt sent to your system. The register is set to
“disable interrupt” after power-on or a hardware reset signal. Thus, no interrupt will be generated
before this register is activated even if user enables the add-on interrupt! In order to enable the
PCI-interrupt, always write 43h to this register. Write 03h to this register if you want to disable the
PCI interrupt.
Here’s the format of the PCI interrupt control register:
Bit 31 - Bit 7
Bit 6
Bit 5 -Bit 3
Bit 2
Bit 1 - Bit 0
Not used
Interrupt Enable
Not used
Interrupt Flag
Interrupt Select
Bit 6: Write a ‘1’ to enable the PCI-interrupt and a ‘0’ to disable PCI interrupt.
Bit 2: This bit is readable but can’t be written. A ‘1’ indicates that Add-on has generated interrupt,
‘0’ means that add-on hasn’t generated interrupt.
Bit 1-0: Always write 1 to these two bits.
Notes:
1. Because PCI-1002 series supports “Plug&Play”, the interrupt number will be automatically assigned by your
system. Use the standard PCI mechanism or the software in our library to find out the interrupt number.
2. If your system supports “Shared IRQ”, several peripherals will share the same IRQ at the same time. You
must use Bit-2 to find out if this IRQ was generated from your PCI-1002 series.
3. For more information about the PCI interrupt control, refers to the PLX-9050 user reference manual.

6.2.2 Section2
This section is used by the add-on control logic. 64 bytes of I/O locations are used. Detailed
descriptions are shown below.
6.2.2.1 The 8254 Registers
The 8254, programmable timer/counter is used to generate periodic AD trigger signals, periodic
interrupt signals and the machine- independent timer for PCI-1002. Addresses 00h, 04h, 08h and
0Ch are used to control the 8254.
Timer 0 is used as Pacer 0. Timer 1 is used as Pacer 1. Timer 2 is used as a machine-independent
timer, P1002_Dealy(). For more details about the programming information, please refer to Intel’s
“Microsystem Components Handbook”.
6.2.2.2 The DI/DO Registers
Address 20h is used for DI / DO ports. Writing to this port will write data to DO register. Reading
from this port will read the data from DI.
6.2.2.3 The AD Buffer
Address 30h is used for AD buffer. Only read operations are available at this address. Reading from
this port will read the data from AD buffer. The format of AD buffer is:
Bit 15 - Bit 12 Bit 11 - Bit 0
Analog Input Channel AD Data
Bit 15-12: The channel number of analog input. Only the lower 4 bits of the channel number are
shown in this register.
Bit 11-0: The AD data.

indicates analog input is differential.
Bit 0 : AD ready signal. ‘0’ indicates not ready, AD is under conversion. ‘1’ indicates ready, AD is
completely converted and is idle now.
6.2.2.5 The AD Software Trigger Register
Writing to this port (1Ch) will generate an AD trigger pulse signal.
Note: Although a very fast trigger can be performed (more than the speed of AD controller, 110 K) via this method, a
reasonable delay time should be left between the two triggers.

6.2.2.6 Clear Interrupt
Reading from 1Ch will clear the add-on interrupt.
6.2.2.7 The Analog Input Selection Register
Address 10h is used by the analog input channel selection register and address 14h is used by the
analog gain control selection register. Write 0-31 to port 10h to select the channel number (for
differential input, write 0-15). Write 0-3 to port 14h to select the gain control.
Figure 6-2: Analog input control.
Notes:
1. For Single-ended Inputs, channels 0-31 are available. For Differential Inputs, channels 0-15
are available. Input numbers which are more than the available channel will be discarded.
Thus, for single-ended inputs, only the last 5 bits are taken as the channel number. And for
differential inputs, only the last 4 bits are taken as the channel number.
2. Only the last two digits are taken as the gain control code. The gain control code and the
corresponding gain is:
For PCI-1002L/LU and PEX-1002L:
[Bit1, Bit0]
[0 0]
[0 1]

6.2.2.8 The General Control Register
A general control register (18h) is used to control the add-on interrupt signal source and the AD
trigger method. The format of this register is:
Bit 4 - Bit2
Bit 1 – Bit 0
Interrupt source selection register
AD trigger method selection register
Interrupt Source Selecti on Re gister
There are four interrupts selectable for PCI-1002 series card (refer to Section 1.2.5 “Interrupt

[Bit 4, Bit 3, Bit 2]
Descriptions
[0, 0, 0]
No interrupt source, disable all interrupts.
[0, 0, 1] Interrupt after AD completes conversion.
[0, 1, 0]
Interrupt after 8254 timer 0 falls.
[0, 1, 1]
Interrupt after external trigger falls.
[1, 0, 0]
Interrupt after 8254 timer 1 falls.
Others No interrupt source, Disable all interrupts.
Note: Bit 2-4 of general control register is set to 0 after hardware reset.
AD Trigger Method Selection Regi ster
Here’s a list of our trigger options (refer to Section 1.2.4 “AD Trigger Methods”):
[Bit 1, Bit 0] Descriptions
[0, 0]
General trigger mode.
8254 timer 0 trigger (internal pacer trigger) or software trigger.
[0, 1]

User Manual, Ver. 3.0, Jun. 2018, PMH-015-30, Page: 51
Notes:
1. In general trigger mode, both 8254 timer 0 and software triggers are treated as AD trigger signals. In this
mode, 8254 timer 0 and software trigger should not work at the same time!! This means users should not
generate the software trigger while 8254 timer 0 is activated.
2. In external clock trigger mode, external trigger input is taken as the AD trigger signal. An event of the external
trigger input fall (falling edge) will generate one AD trigger.
3. The pre-trigger mode is used for pre-trigger method. The mode is incorporated with the 8254 timer 1. First,
setup 8254 timer 1 properly. Then set the trigger mode to pre-trigger. Once pre-trigger mode has been activated,
the 8254 timer 1 will automatical l y turn on and start to perform A D t ri gger s . It wi ll continue until the AD trigger
logic receives a falling external trigger signal. Any change to the trigger mode selection will turn off the
pre-trigger mode.
4. The post-trigger mode is used for post-trigger method. The mode working incorporated with the 8254 timer 1.
First, setup 8254 timer 1 properly. Then set the trigger mode to post-tr i gge r. Once post-trigger mode has been
activated, the 8254 timer 1 will automatically turn off until it receives a falling external trigger signal. Any change
to the trigger mode selection will turn off the post-trigger mode.
5. The AD trigg er is set to 0 aft er eit her pow er -on or hardware reset.

7.3 The AD Timer
The AD trigger is controlled by on-board AD trigger controller. The function diagram of AD trigger is
shown below:
Figure 7-3: AD trigger controller.
AD trigger logic receives the external trigger and then performs the correct AD trigger function. In
order to be recognized by the AD trigger controller, the external trigger signal must be a TTL
compatible signal, with the minimum duration of pulse width to avoid noise. This signal must satisfy
the following specifications:

7.4 AD Conversion
An AD conversion can be initiated in one of three ways: software command, internal programmable
interval timer, or by external trigger to the AD. At the end of the AD conversion, it is possible to
transfer the data in two ways: by polling a status register and reading data when ready, or by
generating a hardware interrupt signal to call service routine. All operating modes are selected by a
control register on the PCI-1002 series.
Before using the AD conversion function, please follow this checklist:
AD data register (BASE+30h) store the AD conversion data.
AD data conversion ready register (BASE +10h)
Check AD conversion ready.
AD gain control register (BASE+14h) Select gain.
AD multiplex control register (BASE+10h) Select analog input channel.
AD mode control register (BASE+18h) Select trigger mode and interrupt source.
AD software trigger control register (BASE+1Ch).
JP1 to select single-ended or differential input.
3 Trigger logic: Software, Pacer or External trigger.
2 Transfer logic: Polling or Interrupt.

AD conversion flow:
Before using the AD converter, please select either single-ended or differential input (JP1).
The software driver supports two different modes: polling and interrupt. The user can control the
AD conversion by polling mode very easy. Using the software driver is recommended if using
interrupt.
The multiplexer can select 32 single-ended or 16 differential signals into the gain control module.
The settling time of multiplexer depends on the impedance of the signal source. Because the
software doesn’t control the settling time, please make sure to leave enough settling time if
switching from one channel to the next channel.
The gain control module also needs settling time if gain control code changed. Again, because the
software doesn’t control settling time, please delay enough settling time if the gain control code is
changed.
Remember to delay the extra setting time when gain of channel is changed.
The software driver provides a machine independent timer, P1002_Delay(), for settling time delays.
This subroutine assumes a machine independent timer will be implemented. However, if using call
P1002_Delay(), the counter 0 will be reserved and can’t be used as a user programmable
timer/counter.
The gain control module’s output feeds into the AD converter. The AD converter needs a trigger
signal to start an AD conversion cycle. The PCI-1002 series supports three trigger modes: software,
pacer, and external trigger.

7.4.1 AD Conversion Trigger Modes
The PCI-1002 series supports three trigger modes.
1 : Software Trigger :
Write any value to the AD software trigger control register, BASE+1Ch, and it will initiate an AD
conversion cycle. This mode is very simple but controlling the sampling rate very difficult.
2 : Pacer Trigger Mode :
See section 4.2 for a block diagram for this pacer timer. The sample rate of pacer is very precise.
3 : External Trigger Mode :
When a rising edge of external trigger signal is applied, an AD conversion will be performed. The
external trigger source comes from Pin-19 of CON3.
7.4.2 AD Transfer Modes
PCI-1002 series supports two transfer modes.
1: Polling transfer:
This mode can be used with all trigger modes. You have to disable timer 0 before polling. The
software reads the AD data register from [BASE+30h] when READY bit of Register [BASE +10h] =1.
2: Interrupt transfer:
This mode can be used with either a pacer trigger or external. A hardware interrupt signal is sent to
the PC when an AD conversion is completed.
If using interrupt transfer, it is recommended to use PCI-1002 software driver.

7.4.3 Software Triggers and Polling Techniques
The easiest way to control is by following these steps:
1. Send 00h to AD mode control register (Software Trigger + Polling Transfer)
2. Send channel number to multiplexer control register.
3. Send the gain control code value to gain control register.
4. Send any value to software trigger control register to generate a software trigger signal.
5. Scan the READY bit until READY bit =1
6. Read the 12-bit AD data.
7. Convert this 12-bit binary data to the floating point value.

AD permanently. Each PCI-1002 Series card is already fully calibrated when shipped from the factory,
so it is usually unnecessary to calibrate the board again unless the accuracy is lost.
DEMO7: Find card number.

8.3 Diagnostic Program
8.3.1 Power-on Plug & Play Test
The operation steps for a power-on Plug & Play test are as follows:
Step 1: Power-off PC
Step 2: Install PCI-1002 without any extra external connector
Step 3: Power-on PC and check the PC screen very carefully
Step 4: The PC will perform a self-test first
Step 5: Detect the non-PCI physical devices installed in the system
Step 6: Show the information of these device in screen
Step 7: Detect the PCI Plug & Play devices installed in the system
Show all PCI-device information check here carefully
There will be a PCI device with vendor_ID=1234, device_ID=1002 (PCI-1002 series)
If the Plug & Play ROM-BIOS detects the PCI-1002 series card during the power-on time, the
software driver of DOS, and Windows 95/NT/2000/XP will function well later. If the Plug & Play
ROM-BIOS can’t find the PCI-1002 series, all software drivers will not function. Therefore the user
must make sure that the power-on procedure is correct.
8.3.2 Driver Plug & Play Test
Step 1: Power-off PC.
Step 2: Install PCI-1002 without any extra external connectors.
Step 3: Power-on PC. Run DEMO7.EXE of DOS.
Step 4: The I/O base address of all PCI-1002 installed in the system will be shown in screen.
Step 5: Is the total number of boards correct?
Step 6: Install a 20-pin flat cable into one of these PCI-1002 cards.
Step 7: One card’s DO=DI This is the physical card number. Remember this number.
Step 8: Repeat the previous two steps to find the physical card number for each board.
