Connecting a flat panel display
Due to the varied selection of available flat panels, the XE–800 SBC is factory
configured and programmed for a VGA/SVGA/XVGA CRT monitor. If you are using
a flat panel, you must reprogram the video BIOS with the appropriate flat panel
driver. To reprogram your video BIOS refer to
Programming the video BIOS
in this
chapter. Note that 3V flat panels are supported through the connector, while 5V
panels require an alternate power source.
The Utility zip file (page 113) contains text files for each of the supported flat
panels. These text files include wiring diagrams specific to individual flat panels.
Refer to the specific text file associated with your flat panel to build an interface
cable, and to determine the correct settings for the flat panel jumpers. Flat panel
displays are connected using a 40-pin connector at J1.
Table 10–2 shows the pinout for the connector for flat panels.
Flat panels requiring bias voltage
Some flat panels require a bias voltage. To determine if your flat panel requires
bias voltage, refer to the text file in the Utility zip file which is specific to your flat
panel or refer to your flat panel information. If your flat panel requires a bias
voltage, refer to the manufacturer’s documentation for procedures on supplying the
proper bias voltage.
WARNING!
Since improper voltage levels can severely damage the flat panel,
make sure the bias voltage is correct before the flat panel is
connected to the XE–800 SBC.
Connecting the flat panel to the XE–800 SBC
Text files are located in the Utility zip file. These text files include wiring diagrams
specific to individual flat panels. Refer to the specific text file associated with your
flat panel to build your cable. The maximum recommended cable length is 18
inches. Table 10–2 shows the pinout for the flat panel connector.
1. Ensure that the Video jumper (W1[5–6]) is installed.
2. Refer to the text file associated with your flat panel to determine the supply
voltage for your panel, and whether a bias voltage is required.
3. Connect a cable from the flat panel to the flat panel connector. Refer to Figure
10–2.
Warning
Improper wiring or connection from the flat panel to the XE–800 SBC
can damage the XE–800 SBC and the flat panel. Verify the flat panel
cable connections before connecting the cable to the XE–800 SBC and
applying power to the system.
Note
See Appendix A – Connectors for mating information.
