Congratulations and thank you for purchasing the new

USB 2.0 5-Port PCI Express Card (the Card) from Belkin.

The Card is designed to take advantage of the additional

bandwidth and features provided by the new PCI Express I/

O interconnection standard. Installing it will give you device-

upgrade expansion room for many years to come.

Over the last 10 years, PCI has become the mainstream

PC interface; nearly every computer uses the PCI bus

specification. Computers implemented with a 32-bit PCI

bus running at 33MHz yield a maximum data-transfer rate

of only 133.3Mbps. In the current information age, data

size is growing exponentially, driving the demand for faster

and greater transfer rates. The original PCI interface is no

longer sufficient to support this demand. This has led Intel

to develop and popularize PCI Express technology. Belkin’s

line of connectivity solutions adapted to this new standard

offer the most convenient ways to connect your peripherals

for the performance you need.

Common PCI Express bus forms include x1, x2, x4, x8,

and x16, with each form being characterized by a unique

slot design. A one-path transmission on a one-lane (x1) PCI

Express bus can reach speeds of up to 250MB—nearly

double the standard PCI transmission speed. A 16-lane (x16)

PCI Express bus can reach speeds of up to 16Gbps.
