1 Introduction
This manual lists and describes the components of the PCI-723X
family products, which includes:
X PCI-7230: Isolated 16-CH DI and 16-CH DO Card
X PCI-7233: Isolated 32-CH DI Card with COS detection
X PCI-7234: Isolated 32-CH DO Card
X PCI-7234P: Isolated 32-CH DO Card with Source Current
Transistor
X cPCI-7230: Isolated 16-CH DI and 16-CH DO Module for
3U CompactPCI
X LPCI-7230: Isolated 16-CH DI and 16-CH DO Card for low-
profile PCI
X LPCIe-7230: Isolated 16-CH DI and 16-CH DO Card for
low-profile PCI Express
These products have high isolation voltage with either 32 DI or 32
DO channels. The high isolation voltage protects the user’s computer against damage caused by accidental contact with high
external voltage and eliminates troublesome ground loops.
The PCI-7230/cPCI-7230/LPCI-7230/LPCIe-7230 provides 16 isolated inputs and 16 isolated outputs. The PCI-7230/cPCI-7230 isolated I/O channels are isolated to 5000 Vrms, and LPCI/LPCIe7230 isolated I/O channels are isolated to 2500 Vrms (excluding
cables).
The PCI-7233 provides 32 isolated digital input channels with
COS (change-of-state detection).
The PCI-7234/7234P 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-tocomputer. (PCI-7 234 is sink cu rrent D O card , PCI-7234 P is sour ce
current DO card).
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 assignment, are automatically controlled by BIOS software. It does not need any user inter action and
Introduction 1
pre-study for the configurations. This removes the burden of
searching for a conflict-free configuration, which can be very timeconsuming and difficult with some other bus standards.

If any of these items are missing or damaged, please contact the
dealer from whom the product was purchased. Save the shipping
materials and carton for future storage or shipping purposes.
2.2 Unpacking
Your PCI-/cPCI-/LPCI-/LPCIe-723X Series card contains sensitive
electronic components that can be easily damaged by static electricity.
The card should be placed on a grounded anti-static mat. The
operator should wear 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 ca use dama ge to
the module. Ensure that 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 socketed ICs to make sure they are properly seated. Do this only with
the module placed on a firm flat surface.
Note: Do not apply power to the card if it has been damaged.
Installation 21
2.3 Hardware Installation Outline
PCI configuration
The PCI cards (or CompactPCI cards) are equipped with a Plug
and Play PCI controller, it can request base addresses and interrupt in accordance with the PCI standard. The system BIOS will
install the system resource based on the PCI cards’ configuration
registers and system parameters (which are set by syste m 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 recommended that the system resource be assigned by any
other method.
PCI slot selection
The PCI card can be inserted into any PCI slot without any configuration for system resource.
Installation Procedures
1. Turn off the computer.
2. Turn off all accessories (printer, modem, monitor, etc.)
connected to your computer.
3. Remove the computer cover.
4. Select a 32-bit PCI slot. PCI slots are shorter than ISA or
EISA slots, and usually white or ivory in color.
5. 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 compo-
nents.
6. Position the board into the selected PCI slot.
7. Secure the card in place at the rear panel of the system.

3 Register Format
The registers format is described in this chapter. This information
is quite useful for programmers who wish to handle the card by
low-level programming. However, it is recommended that the user
has a deeper understanding of the PCI interface before starting
any low-level programming. This chapter can also assist users in
using the software driver to manipulate this card.
3.1 PCI PnP Registers
This PCI card functions as a 32-b it PCI target device to any m aster on the PCI bus. There are three types of registers: PCI Configuration Registers (PCR), Local Configuration Registers (LCR),
and PCI-723X registers.
The PCR, which is compliant with the PCI-bus specifications, is
initialized and controlled by the Plug and Play PCI BIOS. Users
can study the PCI BIOS specification to understand the operation
of the PCR. Please contact the PCISIG for specifications of the
PCI interface.
The PCI bus controller PCI 9052 is provided by PLX technology
Inc. (www.plxtech.com). For further detail on the LCR, please visit
PLX technology’s website to download the relative information.
Users are not required to understand the details of the LCR if
using the software library. The PCI PnP BIOS assigns the base
address of the LCR to offset 14h of PCR.
The PCI-723X 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
find the base address by using the BIOS function call.
Do not try to modify the base address and interrupt assigned by
the PCI PnP BIOS as it may cause resource conflict within your
system.
Register Format 37
3.2 I/O Registers Format
The PCI-7230/cPCI-7230/LPCI-7230/LPCIe-7230 requires one
32-bit address in the PC I/O address space. Table 3.1 shows the I/
O address of each register with respect to the base address.

4.2 Isolated Digital Output Circuits
On the 7230/7234 series, an external voltage source, minimum
5V, maximum 35 VDC, is necessary to power the internal isolated
circuits. It is connected with the VDD pin, When the isolated digital
output goes to high, the sink current will be from VDD.
On the 7230/7234 series, the VDD pin is used as a “fly-wheel”
diode, which can protect the driver if the loading is inductance
loading such as relay, motor, or solenoid.
The VDD must connect to the external power to form a fly-wheel
current loop.

4.3 Change of State Detection
What is COS?
The COS (Change of State) occurs 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 32 channels input channels. If any channel is changed, the COS detection
circuit generates an interrupt request signal.
Structure of COS detection and Dual Interrupt System
The dual interrupt system is used in PCI-7233. Dual interrupt
occurs when the hardware can generate two interrupt request signals at the same time and the software can service these two
requests with ISR. Note that dual interrupt does not mean the card
occupies two IRQ levels. The two interrupt request signals (INT1
and INT2) come from COS detection output signal #1 and #2. The
INT1 is inserted when any channel from 0 to 15 is changed. The
INT2 is inserted when any channel between 16 to 31 is changed.
The interrupt system is illustrated below.

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 can use the “_7233_CLR_IRQ” function to clear,
INT1, or INT2 IRQ signal state.
