and 16 isolated outputs. The isolated I/O channels are isolated to 5,000 Vrms
(excluding cables).
The PCI-7233 provides 32 isolated digital input channels with COS
(change-of-state detection). The high speed version PCI-7233H provides
32-CH isolated digital input .The isolation voltage of PCI-7233H is high up to
2,500 Vrms (excluding cables).
The PCI-7234 provides 32 isolated digital output (Darlington transistor)
channels. The isolation voltage is high up to 5,000 Vrms (excluding cables),
both channel-to-channel and channel-to-computer.
The PCI-7230/7233/7234 use ASIC PCI controller to interface the board to the
PCI bus. The ASIC fully implement the PCI local bus specification Rev 2.1. All
bus relative configurations, such as base memory address and interrupt

2.2 Unpacking
Your PCI-7230, cPCI-7230, PCI-7233, PCI-7233H or PCI-7234 card contains
sensitive electronic components that can be easily damaged by static
electricity.
The card should be done on a grounded anti-static mat. The operator should
be wearing an anti-static wristband, grounded at the same point as the
anti-static mat. Inspect the card module carton for obvious damage. Shipping
and handling may cause damage to your module. Be sure there are no
shipping and handing damages on the module before processing.
After opening the card module carton, extract the system module and place it
only on a grounded anti-static surface component side up.
Again inspect the module for damage. Press down on all the socketed IC's to
make sure that they are properly seated. Do this only with the module place on
a firm flat surface.
Note: DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN
DAMAGED.
You are now ready to install your PCI Card.

2.3 Hardware Installation Outline
PCI configuration
The PCI cards (or CompactPCI cards) are equipped with plug and play PCI
controller, it can request base addresses and interrupt according to PCI
standard. The system BIOS will install the system resource based on the PCI
cards’ configuration registers and system parameters (which are set by system
BIOS). Interrupt assignment and memory usage (I/O port locations) of the PCI
cards can be assigned by system BIOS only. These system resource
assignments are done on a board-by-board basis. It is not suggested to assign
the system resource by any other methods.
PCI slot selection
The PCI card can be inserted to any PCI slot without any configuration for
system resource.
Installation Procedures
1. Turn off your computer.
2. Turn off all accessories (printer, modem, monitor, etc.) connected to
your computer.
3. Remove the cover from your computer.
4. Setup jumpers on the PCI or CompactPCI card.
5. Select a 32-bit PCI slot. PCI slot are short than ISA or EISA slots, and
are usually white or ivory.
6. Before handling the PCI cards, discharge any static buildup on your
body by touching the metal case of the computer. Hold the edge and
do not touch the components.
7. Position the board into the PCI slot you selected.
8. Secure the card in place at the rear panel of the system.
2.4 Device Installation for Windows Systems
Once Windows 95/98/2000 has started, the Plug and Play function of Windows
system will find the new NuDAQ/NuIPC cards. If this is the first time to install
NuDAQ/NuIPC cards in your Windows system, you will be informed to input
the device information source. Please refer to the “Software Installation
Guide” for the steps of installing the device.

Registers Format
The detailed descriptions of the registers format are specified in this chapter.
This information is quite useful for the programmers who wish to handle the
card by low-level programming. However, we suggest user have to understand
more about the PCI interface then start any low-level programming. In addition,
the contents of this chapter can help users understand how to use software
driver to manipulate this card.
3.1 PCI PnP Registers
This PCI card functions as a 32-bit PCI target device to any master on the PCI
bus. There are three types of registers: PCI Configuration Registers (PCR),
Local Configuration Registers (LCR) and PCI-6308 registers.
The PCR, which is compliant to the PCI-bus specifications, is initialized and
controlled by the plug & play (PnP) PCI BIOS. User‘s can study the PCI BIOS
specification to understand the operation of the PCR. Please contact with
PCISIG to acquire the specifications of the PCI interface.
The PCI bus controller PCI-9050 is provided by PLX technology Inc.
(www.plxtech.com). For more detailed information of LCR, please visit PLX
technology’s web site to download relative information. It is not necessary for
users to understand the details of the LCR if you use the software library. The
PCI PnP BIOS assigns the base address of the LCR. The assigned address is
located at offset 14h of PCR.
The PCI-6308 registers are shown in the next section. The base address,
which is also assigned by the PCI PnP BIOS, is located at offset 18h of PCR.
Therefore, users can read the 18h of PCR to know the base address by using
the BIOS function call.
Please do not try to modify the base address and interrupt which assigned by
the PCI PnP BIOS, it may cause resource confliction in your system.

4.2 Isolated Digital Output Circuits
The connection of isolated digital output is shown as following diagram. The
PCI-7230 need external 10~30V DC power from the VDD pin to provide the
power source of the digital output circuit. The cPCI-7230 and PCI-7234 is
equipped with internal DC-DC converter.
On PCI-7230, an external voltage source, minimum 10V, maximum 35 VDC, is
necessary to power the internal isolated circuits. It is connected with pin-19 of
CN2, When the isolated digital output goes to high, the sink current will be from
VDD.
On PCI-7234 and cPCI-7230, the VDD pin is used as “fly-wheel” diode, which
can protect the driver if the loading is inductance loading such as relay, motor
or solenoid.
You can use the following wiring diagram. The VDD must connect to the
external power to form a fly-wheel current loop.

4.3 Change of State Detection
4.3.1 What is COS?
The COS (Change of State) means when the input state (logic level) is
changed from low to high or from high to low. The COS detection circuit is used
to detect the edge of level change. In the PCI-7233 card, the COS detection
circuit is applied to all the 32 channels input channels. When anyone channel
is changed, the COS detection circuit generate an interrupt request signal.
4.3.2 Structure of COS detection & Dual Interrupt System
The dual interrupt system is used in PCI-7233. Dual interrupt means the
hardware can generate two interrupt request signals in the same time and the
software can service these two request with ISR. Note that the dual interrupt
do not mean the card occupy two IRQ levels. The two interrupt request signals
(INT1 and INT2) are comes from COS detection output signal #1 and #2. The
INT1 is inserted when any channel of 0 ~ 15 is changed. The INT2 is inserted
when any channel of 16 ~ 31 is changed. Fig3.6.1 show the interrupt system.

4.3.3 COS Detection
The following timing is an example of the COS detection. Every DI signal’s
edge change can be detected. All the DI channels edge will be ‘OR’ together
to generate the INT1 or INT2 IRQ signals.
If INT1 or INT2 irq Signals generate, the signal will be latch its state. The user
cam use the “_7233_CLR_IRQ” function to clear, INT1 or INT2 IRQ signal
state.

5.2 Programming Guide
5.2.1 Naming Convention
The functions of the NuDAQ PCI cards or NuIPC CompactPCI cards’ software
driver are using full-names to represent the functions' real meaning. The
naming convention rules are:
In DOS Environment :
_{hardware_model}_{action_name}. e.g.
_7230_Initial()
.
All functions in PCI-7230 driver are with 7230 as {hardware_model}. But they
can be used by PCI-7230 and cPCI-7230. All functions in PCI-7233 driver are
with 7233 as {hardware_model}. But they can be used by PCI-7233 and
PCI-7233H.
In order to recognize the difference between DOS library and Windows 95
library, a capital "W" is put on the head of each function name of the Windows
95 DLL driver. e.g.
W_7234_Initial()
.
5.2.2 Data Types
We defined some data type in Pci_723X.h (DOS) and Acl_pci.h (Windows 95).
These data types are used by NuDAQ Cards’ library. We suggest you to use
these data types in your application programs. The following table shows the
data type names and their range.
