Introduction
The PCI-7396 is a 48/96-bit parallel digital input/output (DIO) card
designed for industrial applications. The plug and play feature of PCI-
Bus architecture make it easy for users to install their systems quickly.
The PCI-7396 emulates two/four 8255 Programmable Peripheral
Interface (PPI) chips. Each PPI offers 3 8-bit DIO ports which can be
accessed simultaneously. The total 6/12 ports can be programmed as
input or output independently.
The PCI-7396 supports external trigger to latch the digital input data.
The function of “Change of State” (COS) interrupt is provided. It
means when anyone of these digital inputs changes its state, an
interrupt will be generated for user to handle this external event.

2.2 Unpacking
Your PCI-7396 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, exact the system module and
place it only on a grounded anti-static surface component sideup.
Note:DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN
DAMAGED.
You are now ready to install your PCI-7396.

2.4 Hardware Installation Outline
Hardware 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.
2.5 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.

2.7 Jumpers’ Description
The PCI-7396 is a ‘plug and play’ add-on card using PCI bus. It is
un-necessary for user to setup its base address and IRQ level to fit the
hardware of your computer system. However, to fit users’ versatile
operation, there are still a few jumpers to set the power-on-states of
all I/O ports.
2.7.1 Power-on-state
For all I/O ports of the PCI-7396, the power-on-states could be pulled
high, pulled low, or floating. It is depended on the jumper settings.
Table 2.1 lists the reference numbers of jumpers and their
corresponding port names.
Jumper Port Name Jumper Port Name
JA1 P1A JA3 P3A
JB1 P1B JB3 P3B
JC1 P1C JC3 P3C
JA2 P2A JA4 P4A
JB2 P2B JB4P4B
JC2 P2C JC4 P4C
Table 2.1 Jumpers and port names list
All the jumpers are identical physically. The power-on-state of each
port can be set independently. To pull all signals low is the default
settings. The following diagram use JA1 as an example to show the
possible settings.
Port A of PPI1 is pulled low.(default setting)
Port A of PPI1 is pulled high.
When the jumper cap is removed, the power-on-state is floating.

DIN-100S is a direct connector for the add-on card that is equipped
with SCSI-100 connector. It is suitable for the simple applications that
do not need isolated connection in front of the digital inputs or outputs
of PCI-7396.
2.8.2 Connect with DIN-96DI
DIN-96DI digital input termination board features high-voltage opto-
isolation on all inputs to prevent floating potential and ground loop
problems from damaging your PC system. It is composed of one TB-
96 base board, one TB-96DI daughter board, and one DIN socket for
easy maintenance, wiring, and installation. It provides 96 channels
that are accessed through a SCSI-100 connector.(see Appendix A1)
2.8.3 Connect with DIN-96DO
DIN-96DO digital output termination board features high-voltage opto-
isolation on all outputs to prevent floating potential and ground loop
problems from damaging your PC system. It is composed of one TB-
96 base board, one TB-96DO daughter board, and one DIN socket for
easy maintenance, wiring, and installation. It provides 96 channels
that are accessed through a SCSI-100 connector. (see Appendix A2)
