The CNX-PAD8 Basic Program
The CNX-PAD8 basic SIMPL Windows program is described below in block
diagrams. The diagrams show the symbols that are required to perform the audio
distribution functions. There may be up to 32 room outputs of a daisy-chained
CNX-PAD8 system but, for clarity, only one is described.
The touchpanel or other user interface must be programmed with eight source select
signals and a room off signal (A), volume up and volume down signals (B), and a
mute signal (C). The signals are sent to the basic symbols that are discussed in this
section. The touchpanel also has to be programmed to receive and utilize button
indicator illuminate signals (D).

The interlock symbol S-3 receives the source selection signals (A) from the
touchpanel. The selected signal is retained and the interlock sends the appropriate
feedback signal (D) to the touchpanel to illuminate the corresponding button
indicator.
