2. Installation 

This is a Mini-ITX form factor (6.7" x 6.7", 17.0 x 17.0 cm) motherboard. Before you 

install the motherboard, study the con

fi

 guration of your chassis to ensure that the 

motherboard 

fi

 ts into it.

Make sure to unplug the power cord before installing or removing the  

motherboard. Failure to do so may cause physical injuries to you and  

damages to motherboard components.

2.1  Screw Holes

Place screws into the holes indicated by circles to secure the motherboard to the 

chassis.  

Do not over-tighten the screws!  Doing so may damage the motherboard.

2.2  Pre-installation Precautions

Take note of the following precautions before you install motherboard components 

or change any motherboard settings.

1.   Unplug the power cord from the wall socket before touching any component.

2.   To avoid damaging the motherboard components due to static electricity, 

NEVER place your motherboard directly on the carpet or the like. Also 

remember to use a grounded wrist strap or touch a safety grounded object 

before you handle components. 

3.   Hold components by the edges and do not touch the ICs. 

4.   Whenever you uninstall any component, place it on a grounded antistatic pad or  

in the bag that comes with the component. 

      Before you install or remove any component, ensure that the power is 

      switched off or the power cord is detached from the power supply.     

      Failure to do so may cause severe damage to the motherboard, peripherals, 

      and/or components.

2.3 Installation of Memory Modules (SO-DIMM)

AD2700-ITX / AD2500-ITX 

motherboard provides two 2

04

-pin DDR3 (Double Data 

Rate 3) SO-DIMM slots.

1. It is not allowed to install a DDR or DDR2 memory module into DDR3

    slot; otherwise, this motherboard and SO-DIMM may be damaged.

2. Please install the memory module from DDR3_A2 slot for the 

fi

 rst 

    priority.

Installing a SO-DIMM

Please make sure to disconnect power supply before adding or    

removing SO-DIMMs or the system components.  

Step 1.  Unlock a SO-DIMM slot by pressing the retaining clips outward. 

Step 2.  Align a SO-DIMM on the slot such that the notch on the SO-DIMM 

matches the break on the slot. 

The SO-DIMM only 

fi

 ts in one correct orientation. It will cause perma-

nent damage to the motherboard and the SO-DIMM if you force the SO-

DIMM into the slot at incorrect orientation. 

Step 3.  Firmly insert the SO-DIMM into the slot until the retaining clips at both 

ends fully snap back in place and the SO-DIMM is properly seated.

2.4 Expansion Slot (PCI Slot)

There is 1 PCI slot on this motherboard.     

PCI slot:

  The PCI slot is used to install expansion card that has the 32-bit PCI   

 interface.

Installing an expansion card

Step 1. 

Before installing the expansion card, please make sure that the power  

supply is switched off or the power cord is unplugged. Please read the  

documentation of the expansion card and make necessary hardware 

settings for the card before you start the installation.

Step 2. 

Remove the system unit cover (if your motherboard is already installed 

in a chassis).

Step 3. 

Remove the bracket facing the slot that you intend to use. Keep the 

screws for later use. 

Step 4. 

Align the card connector with the slot and press 

fi

 rmly until the card is  

completely seated on the slot. 

Step 5. 

Fasten the card to the chassis with screws. 

Step 6.  

Replace the system cover.

2. If you have installed onboard VGA driver from our support CD to your system        

    already, you can freely enjoy the bene

fi

 ts of dual monitor function after your        

    system boots. If you haven’t installed onboard VGA driver yet, please install        

    onboard VGA driver from our support CD to your system and restart your  

    computer.

2.5 Dual Monitor Feature

This motherboard supports dual monitor feature. With the internal VGA output sup-

port (DVI-D, D-Sub and HDMI), you can easily enjoy the bene

fi

 ts of dual monitor 

feature without installing any add-on VGA card to this motherboard. This mother-

board also provides independent display controllers for DVI-D, D-Sub and HDMI to 

support dual VGA output so that DVI-D, D-sub and HDMI can drive same or different 

display contents.

To enable dual monitor feature, please follow the below steps:

1. Connect DVI-D monitor cable to DVI-D port on the I/O panel, connect D-Sub       

    monitor cable to D-Sub port on the I/O panel, or connect HDMI monitor  

    cable to HDMI port on the I/O panel.

D-Sub, DVI-D and HDMI monitors cannot be enabled at the same time. 

You can only choose the combination: DVI-D + HDMI, DVI-D + D-Sub, 

or HDMI + D-Sub.

HDCP Function 

HDCP function is supported on this motherboard. To use HDCP  

function with this motherboard, you need to adopt the monitor  

that supports HDCP function as well. Therefore, you can enjoy  

the superior display quality with high-de

fi

 nition HDCP 

encryption contents. Please refer to below instruction for more  

details about HDCP function.

  What 

is 

HDCP?

HDCP stands for High-Bandwidth Digital Content Protection, 

  a 

speci

fi

 cation developed by Intel

®

 for protecting digital 

entertainment content that uses the DVI interface. HDCP is a

copy protection scheme to eliminate the possibility of 

intercepting digital data midstream between the video source, 

or transmitter - such as a computer, DVD player or set-top box - 

and the digital display, or receiver - such as a monitor, television 

or projector. In other words, HDCP speci

fi

 cation is designed to 

protect the integrity of content as it is being transmitted.

Products compatible with the HDCP scheme such as DVD 

players, satellite and cable HDTV set-top-boxes, as well as few 

entertainment PCs requires a secure connection to a compliant 

display. Due to the increase in manufacturers employing HDCP  

in their equipment, it is highly recommended that the HDTV or  

LCD monitor you purchase is compatible.

 port. 

3 CIR sensors in different angles

1. 

Only one of the front USB port can support CIR function. When 

the CIR function is enabled, the other port will remain USB    

 function.

2. 

Multi-Angle CIR Receiver is used for front USB only. Please do 

not use the rear USB bracket to connect it on the rear panel.  

Multi-Angle CIR Receiver can receive the multi-direction infrared 

signals (top, down and front), which is compatible with most of 

the chassis on the market.

3. 

The Multi-Angle CIR Receiver does not support Hot-Plug 

function. Please install it before you boot the system.

2.7 Jumpers Setup 

The illustration shows how jumpers are 

setup. When the jumper cap is placed on 

pins, the jumper is “Short”. If no jumper cap 

is placed on pins, the jumper is “Open”. The 

illustration shows a 3-pin jumper whose 

pin1 and  pin2 are “Short” when jumper cap 

is placed on these 2 pins.

jumper)      

(see p.2 or 3  No. 13)

Note: CLRCMOS1 allows you to clear the data in CMOS. The data in CMOS in-

cludes system setup information such as system password, date, time, and 

system setup parameters. To clear and reset the system parameters to de-

fault setup, please turn off the computer and unplug the power cord from the 

power supply. After waiting for 15 seconds, use a jumper cap to short 2 pins 

on CLRCMOS1 for 5 seconds.

2.8 Onboard Headers and Connectors

Onboard headers and connectors are NOT jumpers. Do NOT place 

jumper caps over these headers and connectors. Placing jumper caps 

over the headers and connectors will cause permanent damage of the 

motherboard!

These two Serial ATA2 (SATA2) 

(SATAII_1: see p.2 or 3, No. 16) 

connectors support SATA data  

(SATAII_2: see p.2 or 3, No. 8)

cables for internal storage   

devices. The current SATA2   

interface allows up to 3.0 Gb/s  

data transfer rate.
