Introduction

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

z PCI-7224: 24-CH DIO card
z PCI-7248: 48-CH DIO card
z PCI-7296: 96-CH DIO card
z cPCI-7248: 3U CompactPCI 48-CH DIO card
z 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, all the functions are
exactly the same as PCI-7248 except there are 24 channels only. The cPCI­7248 is the 3U CompactPCI version of the PCI-7248. The software is fully
compatible with the PCI-7248. In this manual, the PCI-7224 and cPCI-7248’s
specifications are the same as the PCI-7248 if not specified.

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 cPCI-7248’s extended
version, which include one more latch register and with rear I/O capability.

Every PPI connector offers 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 is corresponding to one PPI chip with 24 DIO points. PCI­7224/7248/7296 are equipped with 1,2, and 4 50-pin male ribbon connectors
respectively. The cPCI-7248 is equipped with one 100-pin SCSI-type
connector.

2.2 Unpacking

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

The card should be put on a grounded anti-static mat. The operator should
wear 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 module before processing.

After opening the card module carton, extract the system module and place it
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 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 7248/96 series product.
