INSTALLATION INSTRUCTIONS
599-00
PULSED SWITCHING MODULE
The 599-00 generates momentary (pulsed) outputs in response to an On/Off switched DC input voltage.
The pulsed outputs, 100 milliseconds in duration, are triggered during the On and Off transitions of the DC
input voltage. The 599-00 was developed primarily to provide momentary inputs for the Model 590-00
Programmable Controller when working with long term DC control voltages. It will work, however, in any
application requiring a pulsed output from a switched DC input.

INSTALLATION
Using the 599-00 to Provide Momentary Inputs for the Model 590 Programmable Controller.
The 590 Controller was designed to be used with momentary contact switches. In such applications, a
button is pressed, the 590 outputs an IR command, and the button is released. If the button is not released,
the 590 will either continue to repeat the same IR command or send no signal at all after the initial burst.
As long as one key is pressed, subsequent actions will be locked out; the other keys (inputs) will not respond.
The 599-00 overcomes this, allowing a system to respond to some change or function in an audio/video
system, triggered by automated actions.
• For example, if an A/V Receiver is turned ON manually, an IR command sequence can be made to turn
a DVD player ON and activate PLAY at the same time.

• 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 converted 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.
