Request all inputs’ status 0S Sig• X3 1 • X3 2 •...• X3 n Each X3 response is the signal
status of an input, starting from
input 1; n is the maximum
number of inputs for this model.
Example (SW 6V): 0S Sig•1•1•1•0•1•0 The input signal is present on
inputs 1, 2, 3, and 5. No signal is
present on inputs 4 and 6.
Request an individual input’s status X2 S X3 X2 ’s signal status = X3 .
