VGA interface connections (SBC-599 only)
The SBC-599 PCI SVGA interface can drive conventional CRT displays and is capable of driving a wide range of flat panel displays, including electroluminescent (EL), gas plasma, passive LCD and active LCD displays. The board has two connectors to support these displays, one for standard CRT VGA monitors and one for flat panel displays.
CRT connector (CN16)
CN16 is a standard 15-pin D-SUB connector commonly used for VGA.
Pin assignments for CRT connector CN16 are detailed in Appendix B.
Flat panel connector (CN11)
CN11 consists of a 44-pin, dual-in-line header.
The SBC-599 provides a bias control signal on CN11 that can be used to control the LCD bias voltage. It is recommended that the LCD bias voltage not be applied to the panel until the logic supply voltage (+5V or +3.3V) and panel video signals are stable. Under normal operation, the control signal (ENAVEE) is active high. When the SBC-599 power is applied, the control signal is low until just after the relevant flat panel signals are present.
LCD power select (J12)
The SBC-599 PCI SVGA interface supports 5V and 3.3V LCD displays. By changing the setting of J12, you can select the panel video signal level to be 5V or 3.3V.
