16 PCA-6143P User's Manual

IDE hard drive connections

You can attach two IDE (Integrated Device Electronics) hard disk

drives to the PCA-6143P's internal controller. The card comes

with a 40-pin flat-cable piggyback cable. This cable has three

identical 40-pin flat-cable connectors.

Wire number 1 on the cable is red or blue, the other wires are

gray. Connect one end to connector CN1 on the CPU card. Make

sure that the red wire corresponds to pin one 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 using jumpers

on the drives. If you use just one drive, you should set it as the

master. See the documentation that came with your drive for more

information.

Connect the first hard drive to the other end of the cable. Wire

one on the cable should also connect to pin one on the hard drive

connector. You may have difficulty determining the pin number.

Look for a number printed on the drive circuit board. Check the

documentation that came with the drive for more information.

Connect a second drive as described above.

If you need to make your own cable, you can find the pin assign-

ments for the card’s connector in Appendix D.

Parallel Port

You would normally use the parallel port to connect the card to a

printer. The PCA-6143P includes an on-board parallel port,

accessed through a 26-pin flat-cable connector, CN3. The CPU

card comes with an adapter cable which lets you use a traditional

DB-25 connector. The cable has a 26-pin connector on one end
