Quick Installation Guide

1. Getting Started

1.1 Safety Precautions

Warning!

Always completely disconnect the power cord from your
chassis whenever you work with the hardware. Do not
make connections while the power is on. Sensitive
electronic components can be damaged by sudden power
surges. 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. As a safety precaution,
use a grounding wrist strap at all times. Place all electronic
components in a static-dissipative surface or static-shielded
bag when they are not in the chassis.

Always note that improper disassembling action could cause damage to the

motherboard. We suggest not removing the heat sink without correct
instructions in any circumstance. If you really have to do this, please contact
us for further support.

2.2 Jumper and Connector List

You can configure your board to match the needs of your application by setting jumpers. A
jumper is the simplest kind of electric 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 two pins.

The jumper settings are schematically depicted in this manual as follows:

A pair of needle-nose pliers may be helpful when working with jumpers.
Connectors on the board are linked to external devices such as hard disk drives, a
keyboard, or floppy drives. In addition, the board has a number of jumpers that allow you to
configure your system to suit your application.
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.

The following tables list the function of each of the board’s jumpers and connectors.

2.4 Operation Mode explained

Delay mode Condition = Auto on

1) Ignition=OFF. Nothing happens. EPM-1712 is waiting for ignition signals.

2) Ignition=ON. EPM-1712 waits for 10 seconds then turns on the 5VSB rail. After another
second EPM-1712 sends an “ON” signal to the motherboard via the 2 wires connected to
the motherboard’s ON/OFF pins. The motherboard will turn ON and your system should
start booting. The Ignition state will be kept for 60 more seconds so that the motherboard
will start in normal condition.

3) Ignition=ON. Your computer will keep ON.

4) Ignition=OFF. EPM-1712 waits for “Delay-off” in seconds (see jumper chart, Page 9) and
then it turns the motherboard OFF. Your computer should smoothly turn off (shutdown
procedure). After shutdown, 5VSB will still be provided for another “HARDOFF” seconds. In
the event where the shutdown process is longer than “HARDOFF” (Operating System is
stalled, etc), power will be shut down hard, turning off all power rails. During the HARDOFF
procedure, the battery levels will be constantly monitored to prevent deep discharge
situations.

Low Battery Protection:

1) When the battery Voltage is under 10.6V, Low Battery LED will light continually.

2) The battery recovers 10.6V; the Low Battery LED won’t light.

3) After keeping the battery above 10.6V for 180 seconds, EPM-1712 can be automatically
turned on again.

4) If the system is at ON situation, it will automatically shut down if low battery voltage
(10.6V) lasts over 30 seconds.

Start-Protection is active during the first 60s of PC operation

If Ignition is turned ON and then OFF right away, EPM-1712 will keep Ignition signal in ON
position for 60 seconds, allowing your operating system to fully run. Then system will shut
down according to “Off-delay” settings.

ALARM-Out LED Status:

ALARM LED for EPM-1712 Status, please use LED to connect JPC1 pin1 and pin2.
