About this Manual
This is the hardware manual for the emWEB-15WT
.
It gives all necessary information to users and
programmers of the emWEB-15WT. We have tried to keep it compact, so there are no special
sections for users and programmers. I.e. everything that can be said about the serial port is said in
one place (connector layout, signal levels and programming hints). Users that are not programmers
might therefore only read the first sections (Introduction and Installation) and come back to the
detailed sections when they need more information.
The manual starts with an
Introduction
to the emWEB-15WT. This is some prose that describes the
features and architecture of the emWEB-15WT. You should already know this if you have bought the
board! It then discusses some topics about
Installation
of the product.
The rest of the manual then covers
technical details
about the emWEB-15WT.
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 be
suffixed by a “#” character.
Some parts of the text are important. These are visually marked with the following signs:
Some parts of the manual contain 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.
