Introduction
This manual describes the contents of PCI-723X family products. Include:
PCI-7230: Isolated 16-CH DI and 16-CH DI Card
PCI-7233: Isolated 32-CH DI Card with COS detection
PCI-7233H: Isolated High-speed 32-CH DI Card with COS
PCI-7234: Isolated 32-CH DO Card
cPCI-7230: Isolated 16-CH DI and 16-CH DI Module for 3U
CompactPCI
These products are with high isolation voltage and 32 DI or DO channels.
The high isolation voltage protects your computer against damage
caused by accidental contact with high external voltage and eliminates
troublesome ground loops.
The PCI-7230/cPCI-7230 provides 32 isolated digital I/O, 16 Isolated
inputs 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 assignment, are automatically controlled by BIOS software.
It does not need any user interaction and pre-study for the configurations.
This removes the burden of searching for a conflict-free configuration,
which can be very time-consuming and difficult with some other bus
standards.

8••Installation
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.

2.4 PCI card Installation Outline
2.4.1 Hardware configuration
PCI card has plug and play PCI controller on board. The memory usage
(I/O port locations) of the PCI card is assigned by system BIOS. The
address assignment is done on a board-by-board basis for all PCI cards in
the system.
2.4.2 PCI slot selection
Your computer will probably have both PCI and ISA slots. Do not force the
PCI card into a PC/AT slot. The NuDAQ PCI card can be used in any PCI
slot.
Installation Procedures
1. Read through this manual, and setup the jumper according to your
application
2. Turn off your computer, Turn off all accessories (printer, modem,
monitor, etc.) connected to computer.
3. Remove the cover from your computer.
4. Select a 32-bit PCI expansion slot. PCI slots are short than ISA or
EISA slots and are usually white or ivory.
5. Before handling the PCI-7230/7233/7234, discharge any static
buildup on your body by touching the metal case of the computer.
Hold the edge and do not touch the components.
6. Position the board into the PCI slot you selected.
7. Secure the card in place at the rear panel of the system unit using
screw removed from the slot.

Register & Operation
Theorem
In this chapter, the register format and primitive digital I/O operations of 723X
series products will be specified. The operation theorem of the digital I/O, interrupt
are introduced. Before programming or applying the 723X cards to your
applications, please go through this chapter to understand the features of the
functions.
3.1 I/O Port Base Address
The PCI-723X products function as a 32-bit PCI target device to any
master on the PCI bus. There are three types of registers on the PCI-
723X: PCI Configuration Registers (PCR), Local Configuration Registers
(LCR) and PCI-723X registers.
The PCR, which conform the PCI-bus specifications R2.1, is initialized and
controlled by the system plug & play PCI BIOS. Please refer to the PCI
BIOS specification to understand how to get information from the PCR.
The LCR is specified by the PCI bus controller (PCI-9050). It is not
necessary for users to understand the details of the LCR if you use the
software library. The base address of the LCR is assigned by the PCI PnP
BIOS. The assigned address is located at offset 14h of PCR. Please refer
to the PCI-9050’s data sheet for the detail operation of the LCR and also
the register format of the PCR. For detail information about PCI-9050, you
can download its datasheet from http:\\www.plxtech.com.
The registers of 723X series are shown in the Section 3.2. The base
address of the 723X registers are also assigned by the PCI PnP BIOS.
The assigned base address is stored at offset 18h of PCR. Therefore,
users can read the PCR to get the base address by using the BIOS
function call. Note that the PCI-723X registers are all 32 bits. The users
