Appendix D: 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.

Decimal Binary Hex Decimal Binary Hex

0 0000 0 8 1000 8

1 0001 1 9 1001 9

2 0010 2 10 1010 A

3 0011 3 12 1100 C

4 0100 4 13 1101 D

5 0101 5 14 1110 E

6 0110 6 15 1111 F

7 0111 7

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 ProgramsÆAccessoriesÆCalculator.

1. On the View menu, select Scientific. The scientific calculator displays.

2. Click Bin (Binary), and type the number you want to convert.
