599-00
• When the AM/FM receiver is turned OFF manually, an IR command can also STOP the DVD player and
turn it OFF.
• To do this, the presence or absence of a constant ON and OFF DC voltage must be converted to
momentary pulses to properly operate the Model 590.
• This can be done by using the Model 599-00 connected as shown in
Fig. 2
.
• By plugging the Model 786-00 power supply into the switched AC outlet on the back of an A/V Receiver,
a constant 12 VDC is applied to the 599-00 when the Receiver is powered ON. The 599-00 generates a
short pulse (+12V, 100 mSec) at its
ON
terminal when it first sees +4 to +12V DC at its IN+ and IN–
terminals.
• Similarly, it will generate a short pulse at its
OFF
terminal (+12V, 100 mSec) when the +4 to +12 volts drops
to 0 volts (the A/V Receiver is turned off). Refer to
Fig. 6
.
• This short pulse operation, therefore, permits momentary switches connected to other inputs on the 590
(such as inputs 1 and 2, as in
Fig. 2
) to execute other system commands uninhibited.
Using a Sensing Switch
Fig. 3
shows another example of
how a DC control voltage is con-
verted to momentary ON and OFF
pulses.
• 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 closes, causing the 599-00 to trigger a sequence
of IR commands stored in the 590. The IR commands, for instance, could cause the room lights to dim,
the drapes to close, and music to emanate from the speakers.
