System Features

USB 2.0 Connectors

The Compaq Evo D510 e-pc features 6 USB 2.0 connectors (4 rear and 2 front).
USB 2.0 extends the speed of the connection from 12 Mbps on USB 1.1 to 480 Mbps
on USB 2.0, providing an attachment point for next-generation peripherals for use with higher
performance PCs and user applications. USB 2.0 is both forwards and backwards compatible
with USB 1.1 and uses the same cables and connectors as USB 1.1.
Externally, a USB 2.0 system looks no different from a USB 1.1 system except for the
identifying logos:
USB 1.1 Logo
USB 2.0 Logo
USB 1.1's data rate of 12 Mbps is sufficient for many PC peripherals. These peripherals will
continue to operate with no change in USB 2.0 systems. The higher bandwidth of USB 2.0
permits the use of PC peripherals with wider functionality. The higher bandwidth supports the
most demanding PC user applications, where multiple high-speed peripherals are running
simultaneously. When using a USB hub it is important to make sure that you use a USB 2.0
compliant hub.
USB-to-serial and USB-to-printer adapters are available as optional accessories with the
Evo D510 e-pc. USB-to-serial adapters allow you to connect serial devices through your USB
port, similarly USB-to-printer adapters allow you to connect parallel devices through your
USB port. USB-to-serial adapters require a special driver which can be downloaded from the
