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.

X! = Input number (1 through 4)
X@ = Input signal status: 0 = no signal detected, 1 = signal detected
X# = On/off status: 0 = off, 1 = on
X$ = Switch mode: 1 = normal, 2 = auto
X% = Input number response (1 through 4)

Each X@ response is the signal status of an input, from
input 1 to 4. X@ = 0 (no signal) or 1 (signal detected).
Input 1 = signal present; input 2 = no signal present;
input 3 = no signal present; input 4 = signal present.
