Connecting an LVDS flat panel display
Switch 3 selects the drivers for the supported LVDS flat panel resolutions. Table 9–
2 shows the switch settings for the supported panels. Position 1 must remain On.
Position 2 enables or disables the LVDS support. If you are not using an LVDS flat
panel leave this switch in the On position (disabled) to free up system resources.
Also, if LVDS is enabled and you are using a CRT, the software will not be able to
change the resolution of the CRT.

Connecting the LVDS flat panel to the XE
–900 SBC
Octagon has a custom cable for LVDS, with a connector and 20 flying leads
(Octagon #6772.) Table 9–3 shows the pinout for the flat panel connector. Construct
a custom cable that routes the signals to the appropriate pins for your LVDS flat
panel. To connect a flat panel:
1. Ensure that the Video switch, Switch 2 position 3 is set to On, and that CRT
Analog Output (in the Custom Configuration menu) is disabled.
2. Ensure that the LVDS switches, Switch 3 positions 2 through 6, are properly
set for your resolution.
3. Connect your custom cable from the flat panel to the flat panel connector. Refer
to Figure 9–2.
