Extron electronic DDS 402 manual Command/response table for special function SIS commands

Command/response table for special function SIS commands

The syntax for setting a special function is X? * Xn # where X? is the function number (such as 3 for the “set RGB delay” command in the first example below), Xn is the value or variable (such as 35 in the first example below), and # is the execute command. To view a function’s setting, use X? # where X? is the function number.

In the following table the values of the X? variable are different for each command/ function. These values are given in the rightmost column.
