Supported Emulated Block Transfer Commands

F-9

This example shows the response message in both binary and ASCII.
Note the ASCII information beginning with word 9. The parameter name
characters return in reverse order for each word. Word 9 has the ASCII
value of (aM). To read this, reverse the word to read (Ma). The next word
(ix), reversed, gives you (xi). These words, along with the following two
words, form the word Maximum. You can see the parameter name
Maximum Voltage in word 9 through word 16 of the response message.
In addition, words 21 – 22 are also returned in this format. These words
provide the units in which the parameter is defined. In this example it is
Vlts.

Word 17 contains the file, group, and element which are used to
reference the parameter.

Words 18 – 20 contain the minimum, maximum, and default values of
this parameter.
