12 Introduction to the PanelView Plus CE Terminal
Input/Output
An INTEL 82801BA I/O CONTROLLER HUB (ICH2) provides an
interface between the CPU/Memory/Graphics logic, the PCI bus and
the I/O devices.
The main features integrated into the ICH2 are:
• 10/100BaseT Ethernet
• Dual UHCI USB host controllers support 2 downstream ports
each
• Two IDE Interfaces.
• PCI Bridge
• LPC Interface to the LPC47N267 Super I/O Controller (SIO) and
the Firmware Hub
• RTC embedded
• AC97 Interface
LAN Interface
10/100Mb Ethernet functionality is integrated within the ICH2. The
PHY is an Intel 82562ET that is wired to an RJ-45 connector. A green
LED indicates a good connection. A yellow LED indicates that the
transmitter is active.
USB Ports
The ICH2 has 2 USB host controllers, which support both full 12MHz,
and sub-channel 1.5MHz speeds. The 2 external USB ports come from
the primary host controller. The secondary host controller is wired to
the display interface connector and the PCI connector for future
usage. They are unsupported in the current product. All USB ports
support 500mA per port on the Vcc.
The USB port is capable of supporting a variety of peripheral devices,
for example keyboards, printers, bar code readers, and storage
devices. The platform supports:
• USB HID Class - Keyboard, mouse, bar code reader
• USB Printer Class - PCL compatible printers
• USB Storage Class - Flash drives
IDE
The primary IDE channel of the ICH2 supports the internal Compact
Flash card. The secondary channel is unused.
