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 HS-6252 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
PROTECTION

General Description
The HS-6252 is a 133MHz FSB VIA VT8601 chipset-based board
designed for PCI-ISA Bus with VIA C3 800MHz Embedded CPU.
These features combine and make the HS-6252 an ideal all-in-one
industrial single board computer. Additional features include an
enhanced I/O with CRT, Dual LAN, and 4 COM ports interface.
Its onboard ATA/33/66/100 to IDE drive interface architecture allows
the HS-6252 to support data transfers of 33, 66 or 100MB/sec. to each
IDE drive connection. Designed with the VIA VT8601 core logic
chipset, the board supports VIA C3 800MHz Embedded CPU. The VIA
VT8601 integrated Trident 3D supporting AGP Bus.
For suitable installation into any size system with 8/16/32-bit ISA and/or
PCI slots operation, the board’s advanced PCI-ISA bus add-on feature
allows user to easily obtain both ISA's 16-bit and PCI's 32-bit full set
signals from a half-size PCI-ISA slot. System memory is also sufficient
with the two DIMM sockets that can support up to 1GB.

2
Additional onboard connectors include an advanced USB and IrDA
ports providing faster data transmission, a DOS-compatible
DiskOnChipsocket with a maximum capacity of 288MB, and two
external RJ-45 connectors for 10/100 Based Ethernet use.
To ensure the reliability in an unmanned or standalone system, the
Watchdog Timer (WDT) onboard HS-6252 is designed with pure
hardware that does not need the arithmetical functions of a real-time
clock chip. If any program causes unexpected halts to the system, the
onboard Watchdog Timer (WDT) will automatically reset the CPU or
generate an interrupt to resolve such condition.

Unpacking
2.1 Opening the Delivery Package
The HS-6252 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 that might have occurred during

3.5 Configuring the CPU
TheHS-6252 embedded with a VIA C3 800MHz CPU. User don’t need
to adjust the frequently and check speed of VIA C3 800MH CPU
3.6 System Memory
The HS-6252 provides two DIMM sockets at locations DM1 and DM2.
The maximum capacity of the onboard memory is 1GB.
3.7 DiskOnChipAddress Setting
The DiskOnChipfunction allows the system to boot or operate
without a FDD or a HDD. DiskOnChipmodules may be formatted as
drive C or A. With DiskOnChip, user may also execute DOS
commands such as FORMAT, SYS, COPY, XCOPY, DISCOPY and
DISKCOMP etc.
The U6 location onboard the HS-6252 is the DiskOnChipmodule
socket. Jumper JP4(1-4) assigns the starting memory address of the
installed module. If you have another memory device that has a similar
memory capacity with that of the DOC in your system, please set both
at different memory address mapping to avoid the mapping area
conflicts. Failing to do so will not make the HS-6252 and the additional
memory device function properly.

3.7.1 Installing DiskOnChipModules
When installing a DiskOnChipmodule onto your board, please take
note of the following:
1. Orient yourself properly with the location of the DiskOnChip
socket. Try to locate the pin 1 location on your socket. Pin
numbers are usually printed on either the component side or the
solder side of your board.
2. Locate the Pin 1 location on your DiskOnChipmodule. More
often than not, Pin 1 can be found on the lower right corner of
the chip. Please refer to the diagram for the exact location.

11
3. Once you have figured out where the pin 1 locations are on both
chip and socket, align the module’s pins on an upright angle
against the socket. Using both thumbs, gently press the module
into the socket until all the pins are secured to their
designations.

4. The installation is now complete and your module is now ready
for use.
NOTE: If you encounter difficulty installing your DiskOnChip

module,
please consult a qualified technician or engineer to perform the
installation.
3.7.2 Removing DiskOnChipModules
When removing a DiskOnChipmodule from its socket, please take
note of the following:
1. Loosen the contact of the module from its socket using a
screwdriver.
2. Insert the screwdriver’s flat head into a gap on either end of the
socket. Do not insert the screwdriver head on either side where
the pins are located. Doing so might damage the pins in the
process.
3. Slowly lift the screwdriver handle upwards. This will disengage
the module from its socket.
NOTE: If you encounter difficulty removing your DiskOnChip
 module,
please consult a qualified technician or engineer to remove it for
you.
