Introduction

The 7248/7296 series products are general purpose digital I/O cards. This
series includes four cards:

• PCI-7224: 24-CH DIO card

• PCI-7248: 48-CH DIO card

• PCI-7296: 96-CH DIO card

• cPCI-7248: 3U CompactPCI 48-CH DIO card

• cPCI-7249R: 3U CompactPCI 48-CH DIO card with Rear I/O

The 7248 series products are multi-function digital I/O boards used for
industrial PC with PCI bus or CompactPCI bus. The cards are Plug and Play
therefore it is not necessary to set any jumper for configuration of I/O address
or interrupt resources.

PCI-7248 and PCI-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
specifications for PCI-7224 and cPCI-7248’s are not specified, they are the
same as that of PCI-7248.

The PCI-7248 emulates two industry standard 8255 Programmable
Peripheral Interface (PPI) chips operated under mode zero configuration. The
PCI-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 PC Low. Each
connector corresponds to one PPI chip with 24 DIO points. PCI­7224/7248/7296 are equipped with one, two, and four 50-pin male ribbon
connectors respectively. The cPCI-7248 is equipped with one 100-pin SCSI­type connector.

2.2 Unpacking

Your card contains sensitive electronic components that can be easily
damaged by static electricity.

The card should be placed on a grounded anti-static mat. The operator
should wear an anti-static wristband, grounded at the same poi nt as the anti­static mat.

Inspect the card module carton for obvious damage. Shipping and handling
may cause damage to your module. Ensure there is no shipping and
handling damage on the module before processing.

After opening the card module carton, remove the system module and place
only on a grounded anti-static surface with components side up.

Again inspect the module for damages. Press down on all the socketed IC's
to make sure they are properly seated. Only do this with the module placed
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 7248/96 series product.
