2.1 Jumpers
The PCA-6774 has a number of jumpers that allow you to configure your
system to suit your application. The table below lists the functions of the
various jumpers.
2.2 Connectors
On-board connectors link the PCA-6774to external devices such as hard
disk drives, a keyboard, or floppy drives. The table below lists the func-
tion of each of the board’s connectors

2.5 Setting Jumpers
You may configure your card to match the needs of your application by
setting jumpers. A jumper is a metal bridge used to close an electric cir-
cuit. 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.

2.6 Clear CMOS (J1)
This jumper is used to erase CMOS data and reset system BIOS informa-
tion.
The procedure for clearing CMOS is:
1. Turn off the system.
2. Short pin 2 and pin 3.
3. Return jumper to pins 1 and 2.
4. Turn on the system. The BIOS is now reset to its default setting
Warning! To avoid damaging the computer, always turn
off the power supply before setting “Clear
CMOS.” Before turning on the power supply,
set the jumper back to “3.0 V Battery On.”

2.8 Watchdog timer configuration
An on-board watchdog timer reduces the chance of disruptions which
EMP (electro-magnetic pulse) interference can cause. This is an invalu-
able protective device for standalone or unmanned applications. Setup
involves one jumper and running the control software (refer to Appendix
A).
2.8.1 Watchdog timer output option (J2)
When the watchdog timer activates (CPU processing has come to a halt),
it can reset the system or generate an interrupt on IRQ11. This can be set
via setting J2 as shown below:

17 Chapter 2 Installation
2.9 Installing DIMMs
The procedure for installing DIMMs is described below. Please follow
these steps carefully. The number of pins are different on either side of
the breaks, so the module can only fit in one way. DIMM modules have
different pin contacts on each side, and therefore have a higher pin den-
sity.
1. Make sure that the two handles of the DIMM socket are in the
“open” position. i.e. The handles remain leaning outward.
2. Slowly slide the DIMM module along the plastic guides on both
ends of the socket.
3. Press the DIMM module right down into the socket, until you hear
a click. This is when the two handles have automatically locked the
memory module into the correct position of the socket.
To remove the memory module, just push both handles outward, and the
module will be ejected from the socket.
