E. Binary to Hexadecimal Conversions
Many of the unit’s 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.
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.
