About This Manual

This manual contains information regarding the functions and installation of the Audioaccess

PX-603 Multi-Room Expander in new and existing PX-600 systems. Within it are revised

PX-600 programming instructions and updated KPS switch-setting data that augment the

material in the PX-600 Installation Manual. However, this manual does not contain the

essential instructions covered in the PX-600 Installation Manual.

Before you finalize your system design and begin installation, we suggest you review two

appendices of this manual. The Question and Answer appendix

(Appendix II) contains actual

questions frequently asked by Audioaccess system designers and installers in conversations with

our Technical Support Department and during dealer training sessions. The straight-forward,

forum style explanations will help you better understand the interaction of the PX-600 and

PX-603 and help you make design choices early-on in system planning that will allow you to

configure a system that exactly matches your client’s needs. Furthermore, the System Design

Appendix

(Appendix I) contains real-life descriptions of PX-603 applications, as well as repre-

sentative block and wiring diagrams.

We recommend that even experienced Audioaccess installers and system designers consider the

PX-600 and PX-603 Installation Manuals an essential part of their tool kit. For a complete

Audioaccess Technical Resource Manual which includes installation manuals, tech notes and

tech bulletins, please call our Customer and Technical Support Department at 860-346-0896.

PX-600 Software

To make existing PX-600 systems PX-603 compatible, you will need to upgrade the PX-600

software version to v. 2.0 or later. Earlier PX-600 software versions do not include the pro-

gramming screens for PX-603 setup. To determine the PX-600 software version, plug in the

PX-600 Programmer, press the PGM button, highlight ABOUT PX-600, and press ENTER.

The software version and date will appear on the programmer screen. All PX-600s shipped

after the release of the PX-603 will have v. 2.0 or later software installed.

KPS Software

To make existing KPS keypads PX-603 compatible, you will need to make sure they are

software version 1.6 or above. Earlier KPS software versions will not operate properly in

PX-600/603 systems. To determine the KPS software version, remove the wallplate surround-

ing each keypad and look for a pink dot on the mounting bracket. If a pink dot is not present,

or if the dot is another color, remove the keypad from the wall and remove the rear plate. The

software version should be on the processor I.C. itself. All KPS's shipped since July, 1994 have

software version 1.6 or above.
