Introduction 1
72XX Series
User’s Manual
1 Introduction
The 7248/7296 series products are general purpose digital I/O
cards. This series includes the following cards:
PCI-7224: 24-CH PCI DIO card
PCI-7248: 48-CH PCI DIO card
PCI-7296: 96-CH PCI DIO card
cPCI-7248: 3U CompactPCI 48-CH DIO card
cPCI-7249R: 3U CompactPCI 48-CH DIO card with Rear
I/O
PCIe-7248: 48-CH PCI Express DIO Card
PCIe-7296: 96-CH PCI Express DIO Card
The 7248 series products are multi-function digital I/O boards
used for industrial PCs with PCI, PCI Express, or CompactPCI
buses. The cards are Plug and Play therefore it is not necessary to
set any jumper for configuration of I/O address or interrupt
resources.
The PCI/PCIe-7248 and PCI/PCIe-7296 are 48-channel and 96-
channel DIO cards respectively. PCI-7224 is a reduced version of
PCI-7248, where all functions are exactly the same as PCI-7248
with the exception that there are only 24 channels. The cPCI-7248
is the 3U CompactPCI version of the PCI-7248. The software is
fully compatible with the PCI-7248. In this manual, if the specifica-
tions for PCI-7224, PCIe-7248/7296, and cPCI-7248 are not spec-
ified, they are the same as that of PCI-7248.
The PCI/PCIe-7248 emulates two industry standard 8255 Pro-
grammable Peripheral Interface (PPI) chips operated under mode
zero configuration. The PCI/PCIe-7296 emulates four PPI chips.
These two cards are compatible not only on hardware connectors
but also on software programming.
The cPCI-7248 is the CompactPCI version of PCI-7248. All the
functions are exactly the same as PCI-7248. The cPCI-7249 is an
extended version of cPCI-7248, with an additional latch register
and rear I/O capability.
Every PPI connector has 3 ports: PA, PB, and PC. The PC can
also be subdivided into 2 nibble-wide (4-bit) ports - PC Upper and

User’s Manual
PC Low. Each connector corresponds to one PPI chip with 24 DIO
points. PCI-7224/7248/7296 are equipped with one, two, and four
50-pin male ribbon connectors respectively. The cPCI-7248 is
equipped with one 100-pin SCSI-type connector.
1.1 Features

Programmable interrupt source
Dual interrupt system
1.1.3 Miscellaneous
Provide 12V and 5V power supply on OPTO-22 connectors
On board reset-able fuses to protect power supply for exter-
nal devices
1.2 Applications

1.4 Software Support
ADLINK provides versatile software drivers and packages for dif-
ferent approaches to building systems. We not only provide pro-
gramming libraries such as DLL for many Windows systems, but
also provide drivers for many software packages such as Lab-
VIEW®, HP VEETM, MATLABTM, and many more.
All the software options are included in the ADLINK CD. The non-
free software drivers are protected by serial licensed codes. With-
out the software serial number, the user can still install them and
run the demo version for two hours for demonstration purpose.
Please contact your dealer to purchase the formal license serial
code.
1.4.1 Programming Library
