About this Manual

This is the hardware manual for the emPC-CXR rugged embedded PC.

Conventions

If numbers are specified in this manual, they will be either decimal or hexadecimal. We use C-notation
to identify hexadecimal numbers (the 0x prefix).

If we refer to low active signal names, they

will suffixed by a “#” character.

Some parts of the contains notices you have to observe to ensure your personal safety, or to prevent
damage to property. These are visually marked with the following alert symbols:

DANGER

Indicates that death or severe personal injury

will

result if proper precautions are not

taken.

WARNING

Indicates that death or severe personal injury

may

result if proper precautions are not

taken.

CAUTION

Indicates that

minor

personal injury can result if proper precautions are not taken.

NOTICE

Indicates that damage to equipment can result if proper precautions are not taken.

Indicates information that we think you should have read to save your time by avoiding
common problems. Important suggestions that should be followed will also be marked
with this sign.

Acronyms and Abbreviations

EMC

Electromagnetic capability.

ESD

Electrostatic discharge.

GND

System  ground  potential.  Inside  the  product  this  is  connected  to  the  metal  housing,
which  might  be  connected  to  protective  earth  by  the  installation.  There  exist  some
isolated  reference  grounds  for  communication  interfaces  or  IO.  These  reference
signals are referred to as GND-x, where x indicates function.
