2.3 Setting jumpers
You may configure your card to match the needs of your application by setting jumpers. A jumper is the simplest kind of electrical switch. It consists of two metal pins and
a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To "close" a jumper, you connect the pins with the clip. To "open” a jumper
you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and 3. In
this case you would connect either pins 1 and 2 or 2 and 3.
The jumper settings are schematically depicted in this manual as follows:
A pair of needle-nose pliers may be helpful when working with jumpers.
If you have any doubts about the best hardware configuration for your application,
contact your local distributor or sales representative before you make any changes.
Generally, you simply need a standard cable to make most connections.

The following sections tell how to make each connection. In most cases, you will simply need to connect a standard cable. All of the connector pin assignments are
shown in Appendix A.
Warning! Always completely disconnect the power cord from your chassis when-
ever you are working on it. Do not make connections while the power is
on. Sensitive electronic components can be damaged by a sudden rush
of power. Only experienced electronics personnel should open the PC
chassis.
Caution! Always ground yourself to remove any static charge before touching the
CPU card. Modern electronic devices are very sensitive to static electric
charges. Use a grounding wrist strap at all times. Place all electronic
components on a static-dissipative surface or in a static-shielded bag
when they are not in the chassis.

2.6 IDE Connector (IDE1)
The board provides 1 IDE channel which you can attach up to two enhanced Integrated Drive Electronics hard disk drives or CDROM to the board's internal controller.
This advanced IDE controller supports faster data transfer up to UDMA 100.
Chapter 2 H/W Installation
2.6.1 Connecting the hard drive
1. Connect one end of the cable to Hard Drive connector. Make sure that the red
(or blue) wire corresponds to pin 1 on the connector, which is labeled on the
board (on the right side).
2. Plug the other end of the cable into the Enhanced IDE hard drive, with pin 1 on
the cable corresponding to pin 1 on the hard drive.
(See your hard drive's documentation for the location of the connector.)
If desired, connect a second drive as described above. Unlike floppy drives, IDE hard
drives can connect to either end of the cable. If you install two drives, you will need to
set one as the master and one as the slave by using jumpers on the drives. If you
install only one drive, set it as the master.

PCA-6743 User Manual 16
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-6743 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 covers the end of the slot. Screw in the bracket in place of the plate. Next, attach the flatcable 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.

B Programming the
Watchdog Timer
This appendix contains information of how to program the Watchdog Timer.
B.1 Introduction
The PCA-6743’s watchdog timer can be used to monitor system software operation
and take corrective action if the software fails to function within the programmed
period. This section describes the operation of the watchdog timer and how to program it.
B.1.1 Watchdog timer overview
The watchdog timer is built in to the W83627-DHG-P super I/O controller. It provides
the following user programmable functions:
Can be enabled and disabled by user’s program
Timer can be set from 1 to 255 seconds or 1 to 255 minutes
Generates an interrupt or reset signal if the software fails to reset the timer
before time-out
B.1.2 Programming the Watchdog Timer
The I/O port address of the watchdog timer is 2E (hex) and 2F (hex). 2E (hex) is the
address port. 2F (hex) is the data port. You must first write an address value into
address port 2E (hex), then write/read data to/from the assigned register through
data port 2F (hex).

PC/104 Module
PCA-6743
The PCA-6743 PC/104 connectors give you the flexibility to attach PC/104 modules.
Installing these modules on the PCA-6743 is quick and simple. The following steps
show how to mount the PC/104 modules:
1. Remove the PCA-6743 from your system, paying particular attention to the
safety instructions already mentioned above.
2. Make any jumper or link changes required to the CPU card now. Once the PC/
104 module is mounted you may have difficulty in accessing these.
3. Normal PC/104 modules have male connectors and mount directly onto the
main card. (Refer to the diagram on the following page.)
4. Mount the PC/104 module onto the CPU card by pressing the module firmly but
carefully onto the mounting connectors.
5. Secure the PC/104 module onto the CPU card using the four mounting spacers
and screws.
