Safety Instructions
Integrated circuits on computer boards are sensitive to static electricity. To
avoid damaging chips from electrostatic discharge, observe the following
precautions:
 Do not remove boards or integrated circuits from their anti-static packaging
until you are ready to install them.
 Before handling a board or integrated circuit, touch an unpainted portion of
the system unit chassis for a few seconds. This helps to discharge any static
electricity on your body.
 Wear a wrist-grounding strap, available from most electronic component
stores, when handling boards and components. Fasten the ALLIGATOR clip
of the strap to the end of the shielded wire lead from a grounded object.
Please wear and connect the strap before handle the product to ensure
harmlessly discharge any static electricity through the strap.
 Please use an anti-static pad when putting down any components or parts or
tools outside the computer. You may also use an anti-static bag instead of
the pad. Please inquire from your local supplier for additional assistance in
finding the necessary anti-static gadgets.
NOTE: DO NOT TOUCH THE BOARD OR ANY OTHER SENSITIVE
COMPONENTS WITHOUT ALL NECESSARY ANTI-STATIC
PROTECTIONS.

General Description
The 3308270 is an Intel® 915GV GMCH chipset-based board
designed. The 3308270 is an ideal all-in-one PICMG Bus SBC.
Additional features include an enhanced I/O with CF, CRT/LVDS, dual
GB LAN, audio, SATA, COM, and USB2.0 interfaces.
Designed with the Intel® 915GV GMCH, the board supports Intel®
Pentium® 4 processor 2.8~3.4GHz.
Its onboard ATA/33/66/100 to IDE drive interface architecture allows
the 3308270 to support data transfers of 33, 66 or 100MB/sec. to one
IDE drive connection. The Intel® ICH6 serial ATA controller with two
ports supporting transfer rates up to 150MB/sec.
Onboard Intel® 915GV GMCH chipset for CRT display supporting up
to 1600 x 1200 x 32-bit at 60MHz. It also supports 24-bit single
channel/48-bit dual channel LVDS interface.
System memory is also sufficient with the two DDRII sockets that can
support up to 2GB.
Additional onboard connectors include an advanced USB2.0 port
providing faster data transmission. And two external RJ-45 connectors
for 10/100/1000 Based Ethernet uses.

To ensure the reliability in an unmanned or standalone system, the
watchdog timer (WDT) onboard 3308270 is designed with software
that does not need the arithmetical functions of a real-time clock chip. If
any program causes unexpected halts to the system, the onboard WDT
will automatically reset the CPU or generate an interrupt to resolve
such condition.

Unpacking
2.1 Opening the Delivery Package
The 3308270 is packed in an anti-static bag. The board has
components that are easily damaged by static electricity. Do not
remove the anti-static wrapping until proper precautions have been
taken. Safety Instructions in front of this manual describe anti-static
precautions and procedures.
2.2 Inspection
After unpacking the board, place it on a raised surface and carefully
inspect the board for any damage t hat might have occurred during
shipment. Ground the board and exercise extreme care to prevent
damage to the board from static electricity.
Integrated circuits will sometimes come out of their sockets during
shipment. Examine all integrated circuits, particularly the BIOS,
processor, memory modules, ROM- Disk, and keyboard controller chip
to ensure that they are rmly seated. The 3308270 delivery package
contains the following items:
3308270 Board x 1
