OTHER INTERFACES
6-4 PP 41x/03x
6.2 Keyboard and Mouse Ports
The PP 41x/03x provides PS/2™ type keyboard and mouse interfaces via the front panel Console
connector. This connector also provides a USB interface, which may be used to connect a USB
keyboard or mouse. A splitter cable, part number CB 26D/125-00, is required to access these
interfaces.
6.3 Graphics (VGA) Controller
The PP 41x/03x board contains a Silicon Motion SM722 graphics controller. This device includes 8
Mbytes of graphics RAM and supports many different modes of operation including VGA and
SVGA, with resolutions up to 1280 x 1024 and color depths up to 24 bits (16 million colors). It also
provides both 2D and 3D acceleration. The analog CRT interface from the SM722 is routed to the
front panel Console connector. A splitter cable, part number CB 26D/125-00, is required to access
this interface. The digital flat panel interface of the SM722 is not used on this board.
See also Section 6.1.1 for information about how to switch the PC BIOS console device between
VGA screen and keyboard, and a serial port.
6.4 Real-Time Clock
A conventional PC Real-Time Clock is included on the PP 41x/03x board. This clock is Year 2000
compliant and can be powered by an on-board Lithium battery when main power to the board is
removed. See Section 2.6 for more details of how to fit or replace the battery. The Clock device
also provides 242 bytes of CMOS RAM, in which the PC BIOS keeps much of its setup screen data
and other information.
6.5 Universal Serial Bus (USB)
Four USB interfaces are provided on the PP 41x/03x board. One of these is routed to the front
panel Console connector; the other three are connected to the CompactPCI J5 connector. All four
USB channels support both USB 1.1 and USB 2.0 and can operate at 1.5Mbits/s, 12Mbits/s or
480Mbits/s.
6.6 Power On Self Test LED/Speaker
The Power On Self Test (POST) LED is connected to the PC Speaker port. A connection for this
port is also made available via the CompactPCI J5 connector. This connection is driven by an
open-collector device and can drive a speaker of 32 Ohm or 64 Ohm impedance.
6.7 Audio
The signals for an AC’97 Audio CODEC interface are provided on the CompactPCI J5 connector.
The AD PP5/002-0x Transition Module contains an AC’97 CODEC device and provides
microphone, line input, line output and headphone interfaces. In-board 3.5mm jack sockets on the
Transition Module provide access to these interfaces.
