Flat panel display connector (CN5)
CN5 consists of a 44-pin, dual-in-line header.
The power supply (+12 V) for CN5 is dependant on the supply
connected to the board. Therefore make sure that CN9 is connected to
a +12 V power supply.
The PCA-6753F provides a bias control signal on CN5 which 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
(+5 V or +3.3 V) and panel video signals are stable. Under normal
operation the control signal (ENAVEE) is active high. When the
PCA-6753F board's power is applied, the control signal is low until
just after the relevant flat panel signals are present.
2.10 VGA display connector (CN6)
The PCA-6753F provides a VGA controller for a high resolution
VGA interface. The PCA-6753F CN6 is a DB-15 connector for VGA
monitor input. Pin assignments for the CRT display are detailed in
Appendix A.
2.11 Ethernet connector (CN7)
The PCA-6753F is equipped with a high performance 32-bit PCI-bus
Fast Ethernet interface which is fully compliant with IEEE 802.3u
10/100Base-T specifications. It is supported by all major network
operating systems.
The medium type can be configured via the rset8139.EXE program
included on the utility disk. (See Chapter 5 for detailed information.)
2.12.1 Network boot
The network boot feature is built into the BIOS. It can be enabled or
disabled in the chipset setup of the CMOS configuration. Refer to
"BIOS Setting" in Chapter 4 for more information.
