Graphics Subsystem

th
The structure of the graphics subsystem has changed compared to the predecessor of the Intel 4
TM
generation Core processor. The main graphics interfaces like DisplayPort and DVI are part of the
processor. Only a few sideband signals (DDC/Auxiliary channel, hot plug detection) as well as the VGA
interface is remained at the PCH QM87.
The SC2-PRESTO offers two Mini DisplayPort (mDP) interfaces in the front panel. Adapters to convert
Mini DisplayPort to any other popular interface standard are available.

A 3 DisplayPort is fed to the on-board connector P-DP3. EKF expansion boards like PCS-BALLET
rd
feature the possibility to gain access to the 3 DisplayPort interface.
As an alternate, the SC2-PRESTO can be equipped with an ordinary HD D-Sub 15-lead connector (VGA
style). This connector is suitable for analog signals only. Nevertheless also flat-panel displays can be
attached to the D-Sub connector but with minor reduced image quality.
Independent from the video connector actually in use, Mini DisplayPort, DVI or VGA, the VESA DDC
standard is supported. This allows to read out important parameters, e.g. the maximum allowable
resolution, from the attached monitor. DDC power, +3.3V on DisplayPort connectors, is delivered via
electronic switches to protect the board from an external short-circuit condition (1.5A) and to prevent
back current flows. On the VGA interface a resettable fuse (0.5A) is used supply the +5V DDC power.
Graphics drivers can be downloaded from the Intel web site.

LAN Subsystem

The Ethernet LAN subsystem is composed of four Gigabit Ethernet ports: One Intel i217LM Physical
Layer Transceiver (PHY) using the PCH QM87 internal MAC and three Intel i210IT Gigabit Ethernet
Controllers. These devices provide also legacy 10Base-T and 100Base-TX connectivity. Two of the
Ethernet ports are fed to two RJ45 jacks located in the front panel, the others are attached to the
®
CompactPCI Serial interface on P6. Each port includes the following features:
< One PCI Express lane per Ethernet port (250MB/s)
< 1000Base-Tx (Gigabit Ethernet), 100Base-TX (Fast Ethernet) and 10Base-T (Classic Ethernet)
capability.
< Half- or full-duplex operation.
< IEEE 802.3u, 802.3ab Auto-Negotiation for the fastest available connection.
< Jumperless configuration (complete software-configurable).
Two bicoloured LEDs integrated into the dedicated RJ-45 connector in the front panel are used to
signal the LAN link, the LAN connection speed and activity status. A further bicoloured LED in front
panel labelled EB displays the state of the backplane network ports.
Each device is connected by a single PCI Express lane to the PCH. Their MAC addresses (unique
hardware number) are stored in dedicated FLASH/EEPROM components. The Intel Ethernet software
and drivers for the i217LM and i210IT are available from Intel's World Wide Web site for download.
When managing the board by Intel Active Management Technology (iAMT), the dedicated network
port to do so is accessible by the RJ45 connector GbE1 (the upper port within the front panel).
