Introduction; Primary (Cn1) And Secondary (Cn2) Ide Connectors - Advantech PCA-6277V-00A1 Manual

2.1

Introduction

You can access most of the connectors from the top of the board
while it is installed in the chassis. If you have a number of cards
installed or have a packed chasis, you may need to partially remove
the card to make all the connections.
Note:
2.2 Primary (CN1) and Secondary (CN2) IDE
Connectors
You can attach up to four IDE (Integrated Drive Electronics) drives to
the PCA-6277's built-in controller. The primary (CN1) and secondary
(CN2) connectors can each accommodate two drives.
Wire number 1 on the cable is red or blue and the other wires are gray.
Connect one end to connector CN1 or CN2 on the CPU card. Make
sure that the red/blue wire corresponds to pin 1 on the connector (in
the upper right hand corner). 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 to a single connector, you will need
to set one as the master and the other as the slave. You do this by
setting the jumpers on the drives. If you use just one drive per
connector, you should set each drive as the master. See the documen-
tation that came with your drive for more information.
If your chassis has only one empty expansion slot
to accommodate the CPU card, you can replace the
standard dual-slot bracket with the single-slot
bracket included in your PCA-6277 package, in
which case you will have to access the connectors
(CN31~34) on the extension I/O board from inside
the chassis.
