2.5

IR Connector (JIR1)

This connector supports the optional wireless infrared transmitting and receiving
module. This module mounts on the system case. You must configure the setting
through BIOS setup.
2.6

IDE Connector (IDE1)

The PCA-6742 provides 1 IDE channels which you can attach up to two Enhanced
Integrated Device Electronics hard disk drives or CDROM to the board's internal con-
troller. Its IDE controller uses a PCI interface. This advanced IDE controller supports
faster data transfer up to UDMA 100.
Wire number 1 on the cable is red or blue, and the other wires are gray. Connect one
end to connector CN1 on the CPU card. Make sure that the red (or blue) wire corre-
sponds to pin 1 on the connector. See Figure 2-1, where pin 1 is indicated with a tri-
angle and a solid square.
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 documentation 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 should be labeled on the
drive circuit board. Check the documentation that came with the drive for more infor-
mation. If you are using a second drive, connect it to the remaining connector on the
same cable.
2.7

Compact Flash card Socket (CF1)

The board provides a CompactFlash card type I/II socket. The CompactFlash card
shares a secondary IDE channel.
2.8

Parallel Port Connector (LPT1)

The parallel port is designated as LPT1, and is normally used to connect the CPU
card to a printer. The PCA-6742 includes an onboard parallel port, accessed through
a 26-pin flat-cable connector. The 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 and
a DB-25 connector on the other, mounted on a retaining bracket. The bracket installs
at the end of an empty slot in your chassis, giving you access to the connector.
To install the bracket, find an empty slot in your chassis. Unscrew the plate that cov-
ers the end of the slot. Screw in the bracket in place of the plate. Next, attach the flat-
cable connector to LPT1 on the CPU card. Wire 1 of the cable is red or blue, and the
other wires are gray. Make sure that wire 1 corresponds to pin 1 of LPT1. Pin 1 is on
the right side of LPT1.
2.9 USB Ports (USB12 & USB34)
The PCA-6742 provides up to four ports of USB (Universal Serial Bus) interface,
which gives complete Plug & Play and hot swapping for up to 127 external devices.
