15 RS-232 PORT

Building PHAST cables

RJ-45 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.

Connecting the communication ports other than as described in this manual may damage the AVP2 and the associated components, and will void those products’ warranties.

These ports also provide for extensive home automation flexibility via the PHAST™ protocols, should you be interested in integrating other brands of products into the system in a more comprehensive control system. Your dealer can assist you in taking advantage of these advanced features.

The AVP2 also includes an RS-232 port, which may be used in conjunction with external control systems such as Audioaccess, AMX, or Crestron. Your dealer can assist you in taking advantage of these advanced features.

This RS-232 port may also be used to update the operating software of the AVP2, so that your system will be able to handle new digital audio formats as they are introduced. (Think of updating the software in the AVP2 as be- ing like installing new software in your computer… only much less pain- ful.) Once again, your dealer can assist you in taking advantage of these advanced features, should the need arise.

The “pinout” connections used on the RJ-11 connector used for the RS-232 port is as follows:
