Enhanced Ide Connectors (Cn1); Lcd Interface Connection (Cn2) - Advantech PCA-6145B Manual

2.1 Enhanced IDE connectors (CN1)

You can attach two IDE (Integrated Device Electronics) drives to the
PCA-6145B/PCA-6145L's internal controller. The PCA-6145B/PCA-
6145L CPU card has an EIDE connector, CN1.
Wire number 1 on the cable is red or blue, the other wires are gray. Con-
nect one end to connector CN1 on the CPU card. Make sure that the red
(or blue) wire corresponds to pin 1 on the connector (on the right side).
See Chapter 1 for help finding the connector.
Unlike floppy drives, IDE hard drives can connect in either position on
the cable. If you install two drives, you will need to set one as the master
and one as the slave. You do this by setting the jumpers on the drives. If
you use just one drive, you should set it as the master. See the documenta-
tion that came with your drive for more information.
Connect the first hard drive to the other end of the cable. Wire 1 on the
cable should also connect to pin 1 on the hard drive connector, which is
labeled on the drive circuit board. Check the documentation that came
with the drive for more information.
Connect the second drive as described above on CN1.

2.2 LCD interface connection (CN2)

LCD display connector (CN2)
CN2 consists of a 44-pin, dual-in-line header. Power supplies (+12V)
present on CN2 depend on the supply connected to the board.
The PCA-6145B/PCA-6145L provides a bias control signal on CN2
which can be used to control the LCD bias voltage. It is recommended
that the LCD bias voltage (+5V) and panel video signals are stable. Under
normal operation, the control signal (ENAVEE) is active high. When the
PCA-6145B/PCA-6145L's power is applied, the control signal is low
until just after the relevant flat panel signal is present.
Configuration of the VGA interface is done completely via the software
utility. You don't have to set any jumpers. Refer to Chapter 4 for software
setup details.
