Introduction 1
1 Introduction
The 6743X series products are 64-CH high-density isolated digital
input and/or output cards. The 6743X series products include the
following cards and are available in different form factors.
The following items are PCI bus products:
PCI-67432: Isolated 32-CH DI and 32-CH DO card
PCI-67433: Isolated 64-CH DI card
PCI-67434: Isolated 64-CH DO card
The following items are 3U CompactPCI products:
PXI-67432 : Isolated 32-CH DI and 32-CH DO card
PXI-67433 : Isolated 64-CH DI card
PXI-67434 : Isolated 64-CH DO card with common ground
configuration
PXI-67434P: Isolated 64-CH DO card with common power
configuration
The above I/O cards are isolated up-to 5000 Vdc (excluding
cables) for channel-to-computer isolation. It protects your com-
puter against damage caused by accidental contact with high
external voltage and eliminates troublesome ground loops.
The 6743X series products use PCI-9050 PCI controller to inter-
face the board to the PCI bus. The PCI-9050 fully implements the
PCI local bus specification Rev 2.1. All bus relative configurations,
such as base memory and interrupt assignment, are automatically
controlled by BIOS software.

1.4 Supporting Software
JYTEK provides versatile software drivers and packages for users’
different approach to building a system. We not only provide pro-
gramming libraries such as DLL for many Windows systems, but
also provide drivers for many other software package.
All software options are included in the JYTEK website.

6 Introduction
1.4.1 Programming Library
For customers who are writing their own programs, we provide
function libraries for many different operating systems, including:
DOS Library: Borland C/C++ and Microsoft C++, the func-
tions descriptions are included in this user’s guide.
Windows 95 DLL: For VB, VC++, Delphi, BC5, the func-
tions descriptions are included in this user’s guide.
PCIS-DASK: Includes device drivers and DLL for Windows
2000/XP/Vista. DLL is binary compatible across Windows
2000/XP/Vista. This means all applications developed with
PCIS-DASK are compatible across Windows 2000/XP/
Vista. The developing environment can be VB, VC++, Del-
phi, BC5, or any Windows programming language that
allows calls to a DLL. The user’s guide and function refer-
ence manual of PCIS-DASK are in the CD. Please refer to

2 Getting Started
This chapter describes how to install and setup the 6743X Series
cards. The contents in the package and unpacking information
that you should be aware of are outlined first.
2.1 What You Have
In addition to the User’s Manual, the package should include the
following items:
6743X Board
If any of these items are missing or damaged, contact JYTEK 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.

8 Getting Started
2.2 Unpacking
The PCI-67432/33/34 card contains electro-static sensitive com-
ponents that can be easily be damaged by static electricity.
Therefore, the card should be handled 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 is no
shipping and handling damage on the modules carton before con-
tinuing.
After opening the card module carton, extract the system module
and place it only on a grounded anti-static surface with 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 ATTEMPT TO INSTALL A DAMAGED BOARD IN
THE COMPUTER.
You are now ready to install your card.

10 Getting Started
2.4 Hardware Installation Outline
PCI Configuration
The PCI cards (or PXI cards) are equipped with plug and play PCI
controllers that can request base addresses and interrupts accord-
ing to the PCI standard. The system BIOS will assign the system
resources based on the PCI cards’ configuration registers and
system parameters (which are set by the system BIOS). Interrupt
assignment and memory usage (I/O port locations) can only be
assigned by the system BIOS. These system resource assign-
ments 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 into any PCI slot without any config-
uration of the system resources. The PXI card can also be
inserted into any PXI I/O slot.
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 PXI card.
5. Select a 32-bit PCI slot. PCI slot are shorter 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 compo-
nents.
7. Position the board into the PCI slot you selected.
8. Secure the card in place at the rear panel of the system.

Getting Started 11
For PXI-6743X Products
1. Read through this manual, and setup the jumper accord-
ing to your application needs.
2. Turn off your computer and all accessories (printer,
modem, monitor, etc.) connected to the computer.
3. Remove the cover from the slot of your PXI computer.
4. Select a 32-bit PXI expansion slot on the back plane for
PXI-6743X card.
5. Before handling the PXI-6743X card, discharge any
static buildup from your body by touching the metal cas-
ing of the computer. Hold the edge and do not touch the
components.
6. Position the board into the PXI slot you selected.
7. Secure the card on the back plane by using screws
removed from the slot.

12 Getting Started
2.5 Device Installation for Windows Systems
Once Windows 2000/XP/Vista has started, the Plug and Play func-
tions of the Windows system will find and locate the new NuDAQ/
NuIPC card. If this is the first time a NuDAQ/NuIPC card is
installed in your Windows system, you will be prompted to input
the device information source. Please refer to the JYTEK website
for installation procedures of the device drivers.
