Using the command/response table
The Command/response table for Simple Instruction Set (SIS)
commands is shown at right. The symbols used throughout
the table represent variables in the command/response fields.
Lower and upper case letters are interchangeable, and command
and response examples are shown throughout the table.
The ASCII to HEX conversion table, below, is for use with the
command/response table.
