Please be honest with yourself and ensure that you have understood the previous
sections. If you’re not confident about how binary = HEX = decimal and relates to
ASCII, then you may want to check out the internet for more information on digital

The first thing this writer suggests when learning the following automation protocol –
is to realize that this is a machine talking to another machine – not a human talking to
another human. The automation protocol is written for maximum efficiency, clarity,
and robustness of communication between two machines - all while allowing for
future expansion without requiring us to re-write the protocol every time new
features/products come out (thus commands that work in the new version of software
should work in just about every other previous version/product – which has the exact
same functional control).

The second thing this writer suggests is learning and understanding the HEX notation
– and how to convert decimal numbers and basic ASCII characters (0-9 and A-Z
capitals) into HEX notation. The serial interface works in bytes, and understands
numbers – so the closer you can get to understanding this type of communication –
the easier this will be for you.
