1.1 Introduction

With the SOM-DB4400 and its reference circuits, users may quickly

test their specific SOM-ETX module and easily design their own

solution boards for the SOM-ETX.

Advantech’s new SOM-ETX is a form factor designed to increase

efficiency and effectiveness in embedded systems. This product

facilitates easier system design by eliminating expensive connec-

tors and cumbersome adapter cables. These solutions make it more

simple to customize a system using an off the shelf embedded PC

and reduces the time to market of the product. This standard is a

reference for dimensions and pinouts of SOM-ETX boards. Each SOM-

ETX CPU board provides a different set of features. Please see the

SOM-ETX CPU board manual for details about the product or

contact your supplier to enquire about supported features.

The SOM-ETX boards are interchangeable as long as they provide

the same features (i.e. 2 channel LVDS video output). In order to

maintain this compatibility, ask your supplier or application

engineers for assistance.

To learn about SOM-ETX basic functions, refer to the SOM-ETX

evaluation schematic. This material better explains and clarifies

information about features. Some of the non-standard features,

such as the panel interface, are not usable usless the appropriate

external parts are used.

Parts for EMV/ ESD protection are not included on the SOM-ETX

CPU board.Also note that SOM-ETX signals do not need an

externalPull-upor Pulldown.

If you are creating a backplane for SOM-ETX boards ensure that

you have the appropriate experience with PCI device development.

It is also ideal to be familiar with signal integrity and timing when

laying out your backplane.

1.3 Safety precautions

Warning! Alwayscompletelydisconnect thepower cord from

yourchassis whenever youare working on it. Do

not make connections while the power is on

because sensitive electronic components can be

damagedby the suddenrush ofpower. Only

experiencedelectronicspersonnelshould open

the PC chassis.

Caution! Alwaysground yourself toremove any static

chargebefore touching theCPU 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.
