Connector X3; Graphics; Lcd; Tv-Out - Congatec XTX conga-XLX User Manual

4.3 Connector X3

The following subsystems can be found on connector X3. The implementation of all the
subsystems comply with ETX
and IRQ resources. The necessary resources are allocated by the BIOS during the
POST routine and are configured to be compatible to common PC/AT settings. You can
use the BIOS setup to configure some of the parameters that relate to the specific
subsystems. Check the BIOS Setup Description section for more information about how
to configure a particular subsystem.
4.3.1

Graphics

The conga-XLX graphics are driven by the graphics processor, which is incorporated
into the AMD Geode™ LX800 chip found on the conga-XLX. This graphic processor
offers strong improvements over the original GX core used on Geode™ chipsets in the
past.
4.3.2

LCD

The user interface for flat panels is called EPI (Embedded Panel Interface based on
VESA EDID™ 1.3) and is implemented for both LVDS (National Semi. DS90C363
transmitter) and Digital (AMD Geode™ CS5536 companion device) flat panels. Auto
detection and backlight control are also supported.
4.3.3

TV-Out

Optional TV-Out support is implemented via the Focus FS453 found on the conga-XLX.
4.3.4

Serial Ports (1 and 2)

The conga-XLX offers two serial interfaces (TTL) that are provided by the I/O controller,
which is a Winbond W83627HG super I/O located on the conga-XLX.
4.3.5

Serial Infrared Interface

Serial port 2 can be configured as a serial infrared interface. The Infrared (IrDA)
function provides point-to-point (or multi-point to multi-point) wireless communication,
which can operate under various transmission protocols including IrDA SIR. This feature
is also implemented by the onboard Winbond W83627HG super I/O.
4.3.6

Parallel Port/Floppy Interface

The parallel port/floppy interface can be configured as either a conventional LPT parallel
port or a floppy-disk drive port. This is software implemented and can be configured in
the BIOS setup program. See section 8.5.5 of this document for information about
configuring the parallel port/floppy interface.
Note
When using the onboard floppy interface the floppy drive must be connected via a
