Graphics Interface
The onboard graphics controller supports CRT monitors and a variety of LCD panels with single or dual clock,
color depths of 18/24 bit and resolutions up to UXGA (1600x1200).
9.1
CRT Connector
The CRT monitor interface is available through the X12001 connector (6 pins). To have the signals available
on a standard DSUB-15 CRT monitor connector, an adapter cable is required. A 15-pin DSUB cable is avail-
able from Kontron (KAB-VGA-2, Part Number 96053-0000-00-0).

Layout".
9.2
LCD Panel Connector
The interface for the LCD Panel is available through the X12000 connector (40 pins) on the top side of the
board. This connector represents the JILI interface (JUMPtec Intelligent LVDS Interface). The implemen-
tation of this subsystem complies with the JILI Specification of Kontron Embedded Modules GmbH. A variety
of cables for different display types are available from Kontron. Please refer to the actual cable list on the
Kontron Web site for part numbers and cable names. A detailed description of the JILI interface standard
also is available in a separate document JILI-M???.PDF. The three question marks represent the documents
revision number. You can download this document from the Kontron Web site, or contact your local Kontron
technical support to receive it.

"Connector Layout".

Display Power Considerations
When using a LCD Panel, additional voltages may be required to drive the displays logic and supply the
backlight converter. The display logic may require +5V or +3.3V Backlight converters usually are +5V or +12V
types. When using a Kontron JILI cable, you do not need to determine such configurations. Display logic
voltage come preconfigured on the JILI cable. On occasion, backlight voltage has to be adjusted on the
cable.
Even though the MOPSlcdLX is a +5V only board, you need to supply the +12V for the backlight converter
additionally when using such a converter type. The onboard +3.3V circuitry and the +3.3V logic voltage of
low-voltage panels are powered by separate voltage regulators.
