1. Introduction
This manual describes the 786LCD/mITX board made by KONTRON Technology A/S. The boards will also
be denoted 786LCD family if no differentiation is required.
All boards are to be used with the Intel® Celeron® LV and ULV Processors.
Use of this manual implies a basic knowledge of PC-AT hard- and software. This manual is focused on
describing the 786 Board’s special features and is not intended to be a standard PC-AT textbook.
New users are recommended to study the short installation procedure before switching-on the power.
All configuration and setup of the CPU board is either done automatically or by the user in the CMOS setup
menus. Except for the CMOS Clear jumper, no jumper configuration is required.

!
! Warning: When mounting the board to chassis etc. please notice that the board contains
components on both sides of the PCB which can easily be damaged if board is handled
without reasonable care. A dama
g
ed com
p
onent can result in malfunction or no function at all.
2. Installation procedure
2.1 Installing the board
To get the board running, follow these steps. In some cases the board shipped from KONTRON Technology
has SDRAM mounted. In this case Step 2 can be skipped.
1. Turn off the power supply.
2. Insert the SDRAM module (optional). Be careful to push it in the slot before locking the tabs. For a list of
approved SDRAM modules contact your Distributor or FAE.
PC133,168pin SDRAM modules are supported.
3. Insert all external cables for hard disk, keyboard etc. except for flat panel. A CRT monitor must be
connected in order to change CMOS settings to flat panel support. To achieve UDMA-66/100/133
performance on the IDE interface, 80poled UDMA cables must be used. If using the IDE_S2 connector
care should be taken in correct orientation when attaching the female cable. The cables that KONTRON
provide do not have a key. There is possibility of damage to the HDD or PCB if the cable is not orientated
correctly.
4. Connect power supply to the board by the ATXPWR connector.
5. Turn on the power on the ATX power supply.
6. The PWRBTN_IN must be toggled to start the Power supply; this is done by shorting pins 16
(PWRBTN_IN) and pin 18 (GND) on the FRONTPNL connector (see Connector description). A “normally
open” switch can be connected via the FRONTPNL connector.
7. Enter the BIOS setup by pressing the “F2” key during boot up. Refer to the Software Manual (under
preparation) for details on BIOS setup.
Enter Advanced Menu / CPU Configuration / Intel SpeedStep Tech. and set this option to “Maximum
Performance”.
Note: To clear all CMOS settings, including Password protection, move the CMOS_CLR jumper (with or without
power) for approximately 1 minute. Alternatively turn off power and remove the battery for 1 minute, but be
careful to orientate the battery corretly when reinserted.
8. Mounting the board to chassis
When fixing the Motherboard on a chassis it is recommended using screws with integrated washer and
having diameter of ~7mm.
Note: Do not use washers with teeth, as they can damage the PCB mounting hole and may cause short
circuits.
Note: If the Audio Amplifier shall be used to generate up to 3W on the Audio output channels,
then make sure that sufficent airflow is around the Audio Amplifier. The Amplifier has integrated
Thermal Protection and will not be damaged even though the airflow is insufficient for normal
o
p
eration.

VAROITUS
Paristo voi räjähtää, jos se on virheellisesti
asennettu.
Vaihda paristo ainoastaan laltevalmistajan
suosittelemaan
tyyppiln. Hävitä käytetty paristo valmistajan
ohjeiden
mukaisesti.
When an interface/connector has a VCC (or other power) pin, which is directly connected to a power
plane like the VCC plane:
To protect the external power lines of peripheral devices the customer has to take care about:
•That the wires have the right diameter to withstand the maximum available power.
•That the enclosure of the peripheral device fulfils the fire protecting requirements of IEC/EN 60950.

4. Connector Definitions
The following sections provide pin definitions and detailed description of all on-board connectors.
.
The connector definitions follow the following notation:
Column
name Description
Pin Shows the pin-numbers in the connector. The graphical layout of the connector definition
tables is made similar to the physical connectors.
Signal The mnemonic name of the signal at the current pin. The notation “XX#” states that the signal
“XX” is active low.
Type AI : Analog Input.
AO : Analog Output.
I : Input, TTL compatible if nothing else stated.
IO : Input / Output. TTL compatible if nothing else stated.
IOT : Bi-directional tristate IO pin.
IS : Schmitt-trigger input, TTL compatible.
IOC : Input / open-collector Output, TTL compatible.
NC : Pin not connected.
O : Output, TTL compatible.
OC : Output, open-collector or open-drain, TTL compatible.
OT : Output with tri-state capability, TTL compatible.
LVDS: Low Voltage Differential Signal.
PWR : Power supply or ground reference pins.
Ioh: Typical current in mA flowing out of an output pin through a grounded load, while the
output voltage is > 2.4 V DC (if nothing else stated).
Iol: Typical current in mA flowing into an output pin from a VCC connected load, while the
output voltage is < 0.4 V DC (if nothing else stated).
Pull U/D On-board pull-up or pull-down resistors on input pins or open-collector output pins.
Note Special remarks concerning the signal.
The abbreviation TBD is used for specifications which are not available yet or which are not sufficiently
specified by the component vendors.

Control signal description:
Signal Description
P_OK Active high signal from the power supply indicating that the 5V and 3V3 supplies are within
operating limits. It is strongly recommended to use an ATX supply with the 786LCD/mITX
boards, in order to implement the supervision of the 5V and 3V3 supplies. These supplies are
not supervised onboard the 786LCD/mITX boards.
PS_ON# Active low open drain signal from the board to the power supply to turn on the power supply
outputs. Signal must be pulled high by the power supply.
