2Introduction
2.1 pITX Embedded Line Family
Each pITX is a member of the 2.5" SBC family of KONTRON Technology A/S based on the Pico-ITXTM specifi-
cation (only mechanical outer dimensions) from the Small Form Factor Special Interest Group (SFF-SIG).
pITX embedded line modules are characterized by the same front-line pinouts and interfaces for reset logic
and simple power supply, 2 x USB, Gigabit LAN, S-ATA, Audio, GPIOs, DVI and LVDS interface. These embed-
ded line family features allow to use of the same chassis over the whole product line and maximize design
reuse.
The pITX embedded line modules allow the use of standard laptop memories.
These homogeneous features facilitate easy upgrades within the pITX embedded line product family. Con-
nection of LCD panels is simplified when using the onboard standard JILI30 interface.

asennettu. Vaihda paristo ainoastaan lalteval-
mistajan suosittelemaan tyyppiln. Hävitä käytetty
paristo valmistajan ohjeiden mukaisesti.
3.6 Environmental Specifications
Temperature
Operating (with original KONTRON heat-spreader plate and heat-sink):
³Ambient temperature: 0 to +60°C 1)
Non operating:
³Ambient temperature: -10 to +85°C
Note: 1) It is the customer's responsibility to provide sufficient airflow around each of the components to keep them within the
allowed temperature range.

KTD-S0031-E Page 10 Specifications
KTA55/pITX User's Guide
Humidity
³Operating: 10% to 90% (non condensing)
³Non operating: 5% to 95% (non condensing)
3.7 MTBF
The following MTBF (Mean Time Between Failure) values were calculated using a combination of manufac-
turer’s test data, if the data was available, and a Bellcore calculation for the remaining parts. The Bellcore
calculation used is 'method 1 case 1'. In that particular method the components are assumed to be
operating at a 50% stress level in a 40°C ambient environment and the system is assumed to have not been
burned in. Manufacturer’s data has been used wherever possible. The manufacturer’s data, when used, is
specified at 50°C, so in that sense the following results are slightly conservative. The MTBF values shown
below are for a 40°C in an office or telecommunications environment. Higher temperatures and other envi-
ronmental stresses (extreme altitude, vibration, salt water exposure, etc.) cause lower MTBF values.
³System MTBF (hours): 252839
Note: Fans usually shipped with KONTRON Technology A/S products have 50.000-hour typical operating life. The above esti-
mation assumes no fan but a passive heat sinking arrangement. Estimated RTC battery life (as opposed to battery failures)
is not included in the MTBF calculation. The RTC battery lifetime has to be considered separately. Battery life depends on
both temperature and operating conditions. When the KONTRON unit has external power; the only battery drain is from
leakage paths.

KTD-S0031-E Page 11 Getting Started
KTA55/pITX User's Guide
4Getting Started
Getting started with the KTA55/pITX is simple. Take the following steps:
Plug a suitable DDR3-SDRAM memory module into the RAM socket.
Connect a DVI monitor to the DVI connector.
Plug a keyboard and/or mouse to the USB connector(s).
Attach a harddisk to the S-ATA connector.
Make sure all your connections have been made correctly. Connect the power supply to the
KTA55/pITX power supply connector.
Turn on the board by shortening the power button pins with a push button on power front
panel header (J2401) or use the autostart jumper (J2403).
Enter the BIOS by pressing the Del key during boot-up. Make all changes in the BIOS Setup.
See the BIOS Setup chapter of this manual for details.
5System Memory
The KTA55/pITX uses only 204 pin Small Outline Dual Inline Memory Modules (SODIMMs). One socket is
available for +1.5V unbuffered DDR3-800 or DDR3-1066 SDRAM of up to 4 GB.
The total amount of memory available on the SDRAM module is used for main memory and graphic memory
on KTA55/pITX. Unified Memory Architecture (UMA) manages the sharing of the system memory between
graphic controller and processor. Therefore the full memory size is not available for software applications.
Attention: KONTRON Technology A/S cannot guarantee the correct functionality of the KTA55/pITX when a module faster then
DDR3-1066 is used.

6Graphics Interface
The graphics accelerator supports a DVI interface up to 165 MHz combined with a DisplayPort/LVDS con-
troller with dual clock, color depths of 18/24 bit and resolutions up to 1920x1200 pixel.
6.1 DVI-I Connector
The DVI interface is available through the standard 29 pin DVI-I connector J1100.

To determine whether your flat panel is supported check the Display Cable Guide on the KONTRON web site.
If you use one of those adapters supplied by KONTRON configuration is easy:
Check whether you have the correct adapter and cable for the panel you plan to use. Inspect
the cable for damages. Disconnect the power from your system.
Check jumper J1203 for correct panel voltage (Pos. 1-2 = +3.3V 2-3 = +5V).
Connect an external power supply for the correct backlight voltage (exception: +5V).
Connect the cable to the flat panel connector J1202 on the KTA55/pITX and connect the other
end to your display.
Connect a DVI monitor to the DVI-I connector. Hint: the default boot display setting in the
BIOS Setup is DVI.
Supply power to your system. Enter the BIOS Setup and choose the option 'LVDS' at menu
'Advanced/Display Configuration/Digital Display Port 0' and in addition set the desired display
resolution at 'LVDS Flat Panel Type'.
If you still do not see improvement consider contacting the dealer for technical support.

6.7 Backlight Connector
An external voltage source must be used to supply the backlight with i.e. +12V DC (+5V DC is always avail-
able). The external voltage can be sourced to the backlight connector through the power connector J2901.
This connector can also be used to power the board with +5V DC instead of the round power jacket (see
chapter 'Power Supply').
Note: The backlight voltage that is sourced through connector J2901 can be chosen freely.
6.7.1 External Voltage
Parameter Min. Typ. Max. Units
Input voltage +12.0 +30.0 V
Continuous input current 1.0 A
6.7.2 Backlight Voltage Jumper
Check the jumper J1201 for the correct backlight voltage (Pos. 1-2 = +5V 2-3 = external voltage).
