Lantronix XSENSO 21R2 Manual De Usuario

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.

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

Following are two simple ways to convert binary 
numbers to hexadecimal notation.

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.

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 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.
