Introduction
The PCI-7230 provides 32 isolated digital I/O, 16 Isolated inputs
and 16 isolated outputs. The isolated I/O channels are isolated to
2,500 Vrms (excluding cables), both channel-to-channel and
channel-to-computer. It protects your computer against damage
caused by accidental contact with high external voltage and
elimates troublesome ground loops.
The PCI-7230 uses SAIC PCI controller to interface the board to
the PCI bus. The ASIC fully implement the PCI local bus
specification Rev 2.0. 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.

Installation
This chapter describes the configurations of the PCI-7230 and
teach users to install the PCI-7230. At first, the contents in the
package and unpacking information that you should care about
are described. The PCI-7230 is plug-and-play; it is very easy to
install into any PC system with PCI slots.
2.1 What You Have
In addition to this User's Manual, the package includes the
following items:
•PCI-7230 Isolated Digital I/O Card
•DOS software library and utility
If any of these items is missing or damaged, contact the dealer
from whom you purchased the product. Save the shipping
materials and carton in case you want to ship or store the
product in the future.

6 • Installation
2.2 Unpacking
Your PCI-7230 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-7230.

2.4 PCI-7230 Installation Outline
2.4.1 Hardware configuration
PCI-7230 has plug and play component, the card can requests
memory usage (I/O port locations) of the PCI-7230 is assigned
by system BIOS. The address assignment is done on a board-
by-board basis for all PCI-7230s in the system.
2.4.2 PCI slot selection
Your computer will probably have both PCI and ISA slots. Do not
force the PCI-7230 into a PC/AT slot.

8 • Installation
2.4.3 Installation Procedures
1. Turn off your computer
2. 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 slot are short than ISA
or EISA slots and are usually white or ivory.
Caution !! Don‘t put PCI-7230 card into ISA or EISA slot.
5. Before handling the PCI-7230, 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.
2.4.4 Running the 7230UTIL.EXE
A testing program is included in this utility, you can check if your
PCI-7230 can work properly. Refer Section 5.2 for further
detailed information.

Register Structure & Connection
3.1 I/O Registers Format
The PCI-7230 requires 2 consecutive addresses (32-bit) in the
PC I/O address space. Table 3.1 shows the I/O address of each
register with respect to the base address.
Address Write Read
Base (0 - 3 ) Isolated DO Isolated DI
Table 3.1. I/O Address Map of PCI-7230

3.5 Isolated Digital Output Channels
The connection of isolated-digital output is shown as following
diagram. An external voltage source (5~40VDC) is necessary to
power the internal isolated circuits, and it is connected with pin-
