By plugging the Model 781C-00 power supply into the switched AC outlet on the back of a stereo receiver, a constant 12V DC is applied to the 599. The 599 generates a short pulse (+12V, 100 mSec) at its ON terminal when it first sees +5 to +30V DC at its IN+ and IN– terminals (the stereo receiver is turned on).

Similarly, it will generate a short pulse at its OFF terminal (+12V, 100 mSec) when the +5 to +30 volts drops to 0 volts (the stereo receiver is turned off).

This short pulse operation also permits momentary switches to be connected to other inputs on the 590 (such as inputs 1 and 2, as in Fig. 2). This allows additional system commands, other than those activated by the 599, to be executed uninhibited.

Fig. 3 shows another example of how a DC control voltage is converted to momentary ON and OFF pulses by the 599 Pulsed Switching Module.

For instance, a special SPST sensing switch, as shown, could be mounted in the springs of an over-stuffed chair.

When someone sits down in the chair, the SPST switch is closed causing the 599 to trigger a sequence of IR commands stored in the 590. The IR commands could cause the room lights to dim, the drapes to close, and music to emanate from the speakers.

When the chair is no longer occupied, the SPST switch opens, triggering another set of sequenced commands. These, in turn, could cause the lights to brighten, the drapes to open & the music to turn off.

Many other applications are possible, limited only by the imagination and needs of the installer and user.

---IMPORTANT ---

The 590 inputs that are to be activated by the 599 Pulsed Switching Module must first be programmed with the necessary commands before connecting the 599.

Do this by using the connections and procedures as previously mentioned.

The 590 cannot be programmed through the 599!
