Section 2 - ZonePRO Designer GUI

2.1 ZonePRO Designer Overview

ZonePRO

The ZonePRO Designer Graphic User Interface (GUI) is the included software application which is used for programming the ZonePRO products. The GUI provides network tools for configuring your control network as well as multiple “Wizard” functions for configuring the system routing and in-wall dbx Zone Controllers. The GUI also allows you to adjust DSP effect parameters and even create automatic system changes (referred to as “Scene Changes”).

Understanding the ZonePRO Designer GUI is essential for getting the most out of the ZonePRO processors. After installing the ZonePRO Designer GUI, please see the software application’s help section for detailed information and assistance with the ZonePRO Designer GUI. Training videos are also available at www.dbxpro.com.

2.2 GUI System Requirements

ZonePRO

2.3 GUI Installation

1. Install the ZonePRO GUI software onto your computer from either the dbx website at

www.dbxpro.com or from the included CD ROM.

We highly recommend disabling virus protection software during the installation

of ZonePRO Designer.

2. The application will proceed to prompt you for the installation location.

3. Once the software installation has been completed, it is recommended that you restart

your computer.

2.4 Quick Start – Connecting via RS-232

In order to program the ZonePRO processors, the ZonePRO Designer GUI must be in communication with the ZonePRO device (this is referred to as “Online”). Once communication is established, the ZonePRO processor can be programmed in real-time, or if a program has already been created, it can be loaded into the device.

ZonePRO Designer GUI

Section 2

If your computer does not have a built in RS-232 port you must use a compatible RS-232 peripheral, such as an RS-232 PCI card, RS-232 PCMCIA card, or USB to Serial adapter. Please visit the FAQs section of the dbx website for the latest information on compatible RS-232 peripherals.

Most ZonePRO models also allow you to communicate via Ethernet, the exception being the 640 and 641 models, which do not have an Ethernet control port. If you are connecting via Ethernet and require assistance, please see “Section 6 - Networking”.

It is highly recommended that ZonePRO installers do have the means to communicate with the ZonePRO processors via RS-232. If a firmware update is ever required, the firmware update must be applied using the RS-232 connection!

Going Online via RS-232

1. Connect your computer to the ZonePRO’s front or rear RS-232

port using the provided dbx female to female null modem cable.

A straight-through RS-232 cable will not work! If using a USB to Serial adapter, the dbx null modem cable must be plugged in between the adapter and the ZonePRO. See section “8.8 Wiring Diagrams” for a wiring diagram of the RS-232 null modem cable.
