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.
