1 Introduction
This chapter introduces the PCES-8581-4S/13S PCI Express
®
-
to-PCI Extension System, presents a general overview and basic
applications, its package contents, specifications, and features.
1.1 Overview
Harnessing the bandwidth potential of PCI Express
®
, the PCES-
8581-4S and the PCES-8581-13S smart extension systems
enable computers with a PCI Express
®
slot to remotely manage
and control up to 13 PCI devices, using the high-speed PCI
Express
®
interface. These extension systems operate in 32-bit/33
MHz configuration and come with complete end-to-end hardware
and software transparency for the host system. Hardware devices
installed in the extension system behave and work as if they are
directly installed on the host system, requiring no additional drivers
or software installation.
The host system may be separated from the extension system at
up to seven meters using high-quality shielded twisted copper
cables. The robust and reliable PCI Express
®
-to-PCI extension
systems are suited for portable test and measurement applica-
tions with high-density I/O requirement and are ideal in hazardous
industrial control and automation environments.
1.1.1 Controlling PCI with PCI Express
®
Based on PCI Express
®
technology, PCES-8581-4S and PCES-
8581-13S provide bus expansion capability through the high-
speed differential signal interface. The PCES-8581-4S and PCES-
8581-13S use a signal equalizer and a PCI Express
®
-to-PCI
bridge to architecture a PCI Express
®
to PCI extension system.
With our PCES-8581-4S and PCES-8581-13S, user can use an
available PCI Express
®
slot to control an external PCI chassis.
Because the PCI Express
®
Bridge is a transparent bridge, there is
