7. Binary to Hex Conversion
Many of the unit’s configuration procedures require assembling a series of options (represented as bits) into
a complete command (represented as a byte). Convert the resulting binary value to a hexadecimal
representation.
Following are two simple ways to convert binary numbers to hexadecimals.
7.1.1 Conversion Table
Hexadecimal digits have values ranging from 0 to F, which are represented as 09, A (for 10), B (for 11), etc.
To convert a binary value (for example, 0100 1100) to a hexadecimal representation, the upper and lower
four bits are treated separately, resulting in a two-digit hexadecimal number (in this case, 4C). Use the following
table to convert values from binary to hexadecimal.
Decimal
0
Binary
0000
Hex
0
1 0001 1
2 0010 2
3 0011 3
4 0100 4
5 0101 5
6 0110 6
7 0111 7
8 1000 8
9 1001 9
10 1010 A
11 1011 B
12 1100 C
13 1101 D
14 1110 E
15 1111 F
7.1.2 Scientific Calculator
Another simple way to convert binary to hexadecimals is to use a scientific calculator, such as the one
available on Windows’ operating systems. For example:
1. On the Windows’ Start menu, click Programs/Accessories/Calculator.
2. On the View menu, select Scientific. The scientific calculator displays.
3. Click Bin (Binary), and type the number to convert.
