2.2 sampling Messages
and Their Meaning
•
Within each message, multiple parameters of data must be separated by one "
character.
•
Data pertaining to a source setup other than the current source setup is preceded by: the
letter "S", the source setup number (i.e., channel), and a space. This is similar to an "extra"
parameter P0.
•
Text parameters such as channel names are enclosed in double quotes following the data,
as in "Name".
TexT PaRaMeTeRs: Most data is simply a numerical value, however some messages also
require text. For example, a channel naming message typically includes a text-based name
after the channel number—enclose this text in double quotation marks, as in "Tilt the Wagon".
Use all characters as desired except for the following special characters shown in the left column
below—these require a 2-character combination as shown:
