CE Marking
European standards are being harmonised across borders. If products comply with the same standards in all
European countries, product exporting and importing is made simple - paving our way to a common market. If you buy
a product with a 'CE' mark on it (shown below), on the box, in the manual, or on the guarantee - it complies with the
currently enforced directive(s).
Introduction to EMC
EMC (Electromagnetic Compatibility) is the term used to describe certain issues with RF (Radio Frequency) energy.
Electrical items should be designed so they do not interfere with each other through RF emissions. E.g. If you turn on
your microwave, your television shouldn't display interference if both items are CE marked to the EMC directive.
If emitted RF energy is not kept low, it can interfere with other electrical circuitry - E.g. Cars Automatic Braking
Systems have been known to activate by themselves while in a strong RF field. As this has obvious repercussions
ALL electrical products likely to cause RF related problems have to be 'CE' marked from 1st January 1996 onwards.
If a product conforms to the EMC directive, not only should its RF emissions be very low, but its immunity to RF energy
(and other types) should be high. The apparatus has to resist many 'real world' phenomena such as static shocks and
mains voltage transients.
Viglen’s Environment laboratory
To gain a 'CE' mark, the Viglen computer range has had to undergo many difficult tests to ensure it is
Electromagnetically Compatible. These are carried out in the in-house 'Environment lab' at Viglen Headquarters. We
have made every effort to guarantee that each computer leaving our factory complies fully with the correct standards.
To ensure the computer system maintains compliance throughout its functional life, it is essential you follow these
guidelines.
Install the system according to Viglen’s instructions
If you open up your Viglen:
Keep internal cabling in place as supplied.
Ensure the lid is tightly secured afterwards
Do not remove drive bay shields unless installing a 'CE' marked peripheral in its place
The clips or ‘bumps' around the lips of the case increase conductivity - do not remove or damage.
Do not remove the ferrite ring from the L.E.D cables.
Only use your Viglen computer with 'CE' marked peripherals
This system has been tested in accordance with European standards for use in residential and light industrial areas-
this specifies a 10 meter testing radius for emissions and immunity. If you do experience any adverse affects which
you think might be related to your computer, try moving it at least 10 meters away from the affected item. If you still
experience problems, contact Viglen’s Technical Support department who will put you straight through to an EMC
engineer - s/he will do everything possible to help. If modifications are made to your Viglen computer system, it might
breach EMC regulations. Viglen take no responsibility (with regards to EMC characteristics) of equipment which has
been tampered with or modified.

Universal Serial Bus (USB)
The motherboard has four USB ports and a further five can be added via internal
headers; one USB peripheral can be connected to each port. For more than nine USB
devices, an external hub can be connected to either port. The motherboard fully
supports the universal host controller interface (UHCI) and uses UHCI-compatible
software drivers.
USB features include:
Self-identifying peripherals that can be plugged in while the computer is running.
Automatic mapping of function to driver and configuration.
Supports isochronous and asynchronous transfer types over the same set of wires.
Supports up to 127 physical devices.
Guaranteed bandwidth and low latencies appropriate for telephony, audio, and other
applications.
Error-handling and fault-recovery mechanisms built into the protocol.
NOTE: Computer systems that have an unshielded cable attached to a USB port may
not meet FCC Class B requirements, even if no device or a low-speed (sub-channel)
USB device is attached to the cable. Use shielded cable that meets the requirements for
high-speed (fully rated) devices.
IDE Support
The motherboard has one independent bus-mastering PCI IDE interfaces. These
interfaces support PIO Mode 3, PIO Mode 4, ATAPI devices (e.g., CD-ROM), Ultra
DMA/66 & Ultra DMA/100 synchronous-DMA mode transfers. The BIOS supports logical
block addressing (LBA) and extended cylinder head sector (ECHS) translation modes.
The BIOS automatically detects the IDE device transfer rate and translation mode.
Programmed I/O operations usually require a substantial amount of processor
bandwidth. However, in multitasking operating systems, the bandwidth freed by bus
mastering IDE can be devoted to other tasks while disk transfers are occurring.
LS-120 Support
LS-120 MB Diskette technology enables you to store 120MB of data on a single, 3.5”
removable diskette. LS-120 technology is backward (both read and write) compatible
with 1.44MB and 720KB DOS-formatted diskette and is supported by Windows 95 and
Windows NT operating system.
The Vig627M board allows connection of an LS-120 compatible drive and a standard
3½” floppy drive. The LS-120 drive can be configured as a boot device before a floppy
drive, if selected in the BIOS setup utility.
NOTE: If you connect an LS-120 drive to an IDE connector and configure it as the “A”
drive and configure a standard 3.5” floppy as “B” drive, the standard floppy must be
connected to the floppy drive cable’s “A” connector (the connector at the end of the
cable).
The BIOS setup utility can be configured to boot firstly from either the LS120 or standard
3½”floppy drive.

Real-Time Clock, CMOS SRAM, and Battery
The real-time clock is compatible with DS1287 and MC146818 components. The clock
provides a time-of-day clock and a multi-century calendar with alarm features and
century rollover. The real-time clock supports 256 bytes of battery-backed CMOS SRAM
in two banks that are reserved for BIOS use.
The time, date, and CMOS values can be specified in the Setup program. The CMOS
values can be returned to their defaults by using the Setup program.
An external coin-cell (CR 2032) battery powers the real-time clock and CMOS memory.
When the computer is not plugged into a wall socket, the battery has an estimated life of
three years. When the computer is plugged in, the 3.3-V standby current from the power
supply extends the life of the battery. The clock is accurate to 13 minutes/year at 25 ºC
with 3.3 V applied.
I/O Interface Controller
The motherboard uses the I/O controller which features:
Serial ports:
oInternal send/receive 16-byte FIFO buffer.
oFour internal 8-bit DMA options for the UART with SIR support (USI).
Multimode bidirectional parallel port:
oStandard mode, IBM and Centronics compatible.
oEnhanced parallel port (EPP) mode with BIOS and driver support.
oHigh-speed extended capabilities port (ECP) mode.
Floppy disk controller:
oN82077 compatible.
oSingle diskette drive interface.
o16-byte FIFO.

Serial Ports
The serial port is a 16550A high speed communications port that sends/ receives 16
bytes FIFOs. You can attach a serial mouse or other serial devices directly to the
connector.
Parallel Port
The connector for the multimode bidirectional parallel port is a 25-pin D-Sub connector
located on the back panel. In the Setup program, the parallel port can be configured for
the following:
Compatible (standard mode).
Bidirectional (PS/2 compatible).
Extended Parallel Port (EPP).
Enhanced Capabilities Port (ECP).
Floppy Controller
The I/O controller is software compatible with the N82077 floppy drive controllers and
supports both PC-AT and PS/2 modes. In the Setup program, the floppy interface can
be configured for the following floppy drive capacities and sizes:
360 KB, 5.25-inch
1.2 MB, 5.25-inch
720 KB, 3.5-inch
1.44MB, 3.5 inch
1.2 MB, 3.5-inch (driver required)
2.88 MB, 3.5-inch
PS/2 Keyboard and Mouse Interface
PS/2 keyboard and mouse connectors are located on the back panel. The +5 V lines to
these connectors are protected with a PolySwitch circuit that, like a self-healing fuse, re-
establishes the connection after an over-current condition is removed.
The keyboard controller supports the hot-key sequence <Ctrl><Alt><Del> for a software
reset. This key sequence resets the computer’s software by jumping to the beginning of
the BIOS code and running the Power-On Self Test (POST).
Audio Subsystem
These audio connectors are used for audio devices. You can differentiate the colour of
the audio jacks for different audio sound effects.
Line-In (Blue) - Line In is used for external CD player, tape player or other audio
devices.
Line-Out (Green) - Line Out, is a connector for speakers or headphones.
Mic (Pink) - Mic, is a connector for microphones.

Management Extension Component
System BIOS
The system BIOS, from Phoenix Technology, provides ISA and PCI compatibility. The
BIOS is contained in a flash memory device on the system board. The BIOS provides
the power-on self test (POST), the system Set-up program, a PCI and IDE auto-
configuration utility, and BIOS recovery code.
PCI Auto Configuration
The PCI auto-configuration utility works in conjunction with the Set-up program to
support using PCI add-in boards in the system. When you turn on the system power
after installing a PCI board, the BIOS automatically configures interrupts, DMA channels,
I/O space, and so on. Since PCI add-in boards use the same interrupt resources as ISA
add-in boards, you must specify the interrupts used by ISA boards in the set-up program.
The PCI auto-configuration program complies with version 2.1 of the PCI BIOS
specification.
IDE Auto Configuration
If you install an IDE drive in the system, the IDE auto-configuration utility automatically
detects and configures the drive for operation in the system. This utility eliminates the
need to enter the Set-up program after you install an IDE drive.
Expansion Slots
The system has one PCI bus add-in card connector and one PCI Express x16 connector
and one PCI Express x1 connector.
