12.4 Flat Panel LVDS Interface (JILI)
Connector
The interface for the LCD Panel is available through the X10
connector
(40
pins)
on
the
bottom
connector

the
JILI
LVDS Interface). The implementation of this subsystem complies
with the JILI Specification of Kontron Embedded Modules GmbH.
The coolMONSTER/PM already supports the JILI3 implementation. A
variety of cables for different display types are available from
Kontron. Please refer to the 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
JILIM???.PDF. The three question marks represent the document's
revision number. You can download the document from the Kontron
Web site, or contact your local Kontron technical support to
receive it.

12.5 Display Power Considerations
When using a LCD Panel, additional voltages may be required to
drive the display's logic and to supply the backlight converter
and the display's contrast voltage.
The display logic may require +5V for standard or +3.3V for low-
power LCDs. Contrast voltages for passive displays are normally
very
different
and
can
range
converters usually are +5V or +12V types. When using a Kontron
JILI cable, you do not need to determine such configurations.
Display logic voltage and contrast voltage come pre-configured
on the JILI cable. On occasion, backlight voltage has to be
adjusted on the cable.
Even though the coolMONSTER/PM is also available as 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 of the coolMONSTER/PM and the +3.3V
logic voltage of low-voltage panels are powered by separate
voltage regulators. The one for the LCD is mounted on the JILI
adapter cable.

12.6 Connecting a LCD Panel
To determine whether your panel display is supported, check the
Kontron Web site for panel lists. We regularly update the list
of panels that have been tested with our boards.
Many panel adapters for a wide spread variety of displays are
available through Kontron. If you use one of those adapters
supplied by Kontron, configuration is easy:
1. Check whether you have the correct adapter and cable for the
panel you plan to use. Inspect the cable for damages.
2. Disconnect the power from your system.
3. Connect the panel adapter to the LCD Panel connector (JILI)
on the coolMONSTER/PM.
4. Connect the other end of the cable to your display.
5. Connect the backlight converter.
6. Supply power to your system.
7. If no image appears on your display, connect a CRT monitor to
the CRT connector.
8. If necessary program the EEPROM on the JILI cable with the
matching configuration data.
9. If you still do not see improvement, consider contacting the
dealer for technical support.
12.7 Configuration
You can set the general configuration for the graphic controller
in the BIOS setup utility. Refer to the Advanced Chipset Control
submenu and the Display Control submenu in the Appendix B: BIOS
Operation chapter for more configuration information.
You can download drivers for the graphics controller from the
Kontron Web site. For further information, read the read-me or
help files or contact technical support.
