These two RJ-45 communications ports also support the PHAST™ inter- component communications protocols, greatly simplifying the design and installation of sophisticated home automation systems. They provide two- way communication with the home automation controller as to the amplifier’s current status, ensuring reliable execution of sophisticated turn- on and shutdown macros.

To use these ports, simply daisy chain the various Proceed products to- gether. The modular cable needed for the connection may be purchased from your Proceed dealer. It may also be easily and inexpensively made to length using two modular connectors and the appropriate length (up to 100 feet/30 meters) of flat, eight conductor cable.

Modular cables and connectors are used throughout the world for both tele- communications and computers, and are widely available at low cost. The connectors are crimped on to the ends of the cable such that pin 1 at one end is connected to pin 1 at the other end. Such a “straight-through” con- nection is (counter-intuitively) made by introducing a 180° twist in the cable between the two ends, as shown below.

3REMOTE TURN-ON (“TRIGGER’) JACKS

Two 1⁄8" “mini” jacks above the AC mains receptacle on the rear panel al- lows remote-controlled turn-on (that is, toggling between operate and standby) of the Proceed amplifier. These remote “triggers” will be operated by the presence of 5–12 volts DC, with tip polarity as shown below:

–+

5-12 volts, positive tip polarity

The presence of a suitable DC voltage will cause the amplifier to be fully on; the absence of such a voltage will cause it to enter standby. Your Pro- ceed dealer can help you take advantage of these design features to maxi- mize your system’s versatility.

Since these trigger inputs are wired in parallel, you can go into one and out of the other to facilitate a “daisy-chain” of turn-on triggers (should you have additional products that need to be controlled in this manner).

Special note: if this method of control is used for the amplifier(s), the last mini-jack in the chain must be terminated with a dummy 1⁄8" plug [that is, an empty plug must be inserted into the final 1⁄8" (3.5 mm) jack]. Even if only a single amplifier is controlled in this fashion, the “extra” mini-jack must be terminated.
