Appendix E: Binary to Hexadecimal Conversions
Many unit configuration procedures require you to assemble a series of options (represented as
bits) into a complete command (represented as a byte).
The resulting binary value must be converted to a hexadecimal representation.
Use this chapter to learn to convert binary values to hexadecimals or to look up hexadecimal
values in the tables of configuration options. The tables include:

Command Mode (serial string sign-on message)

AES Keys
Converting Binary to Hexadecimal
Following are two simple ways to convert binary
numbers to hexadecimal notation.
Conversion Table
Hexadecimal digits have values ranging from 0 to F,
which are represented as 0-9, A (for 10), B (for 11),
etc. To convert a binary value (for example, 0100
1100) to a hexadecimal representation, treat the
upper and lower four bits separately to produce a two-
digit hexadecimal number (in this case, 4C). Use the
following table to convert values from binary to
hexadecimal.
Scientific Calculator
Another simple way to convert binary to hexadecimal
is to use a scientific calculator, such as the one
available on the Windows operating systems. For
example:
1. On the Windows Start menu, click All Programs -
> Accessories -> Calculator .
2. On the View menu, select Scientific . The
scientific calculator appears.
3. Click Bin (Binary), and type the number you want
to convert.
