For your convenience, all the configuration and editing features of the ZonePro™ 640 and 641 are performed via the included Zone Pro GUI. This section has been created to act as a tuto­rial for performing various editing aspects of the unit.
The philosophy of the ZonePro 640 and 641 is built around the concept the concept of a con­figuration, a scene and a device file.
Configuration
The configuration includes all of the processing blocks, the I/O configuration, and the zone controllers. The configuration is set up by going through the Configuration Wizard. The ZonePro device can only have one configuration, so all configuration changes must be com­pleted before you start storing scenes. For more information on the configuration see
Configuration Wizard in section 3.
Scenes
A scene consists of the parameters for all the modules and the assignment of zone controllers to a zone. The ZonePro products allow switching of scenes from the Real Time Clock, or from a ZC zone controller. Up to 50 scenes can be stored in the ZonePro unit. For more informa­tion on scenes see section 3.
Device
The configuration, scenes, and schedule information can all be stored off to a device file or .zpd (ZonePro device). Storing a device file to the computer and then recalling it into another ZonePro unit allows for exact duplication of a system in a single file download.
There are three different views within the ZonePro Designer GUI; Venue view, Program screen, and Module view. V
enue view From the Venue View you can add or delete devices and con­figure your network including selecting your COM port. Double clicking on a unit icon in the Venue view takes you to the Program screen. Pr
ogram screen provides you with a graphic representation of the configuration of the individual ZonePro unit, including all the processing modules and their positions in the signal path. The program screen also offers access to meters, scene storing and loading, the Wizard functions, and file storing. Double clicking on the pro­cessing modules take you to the Module view. Module vie
w (also called edit screen) provides
access to the processing parameters. Editing of parameters is done in Module view.
Once the software has been loaded and the ZonePro unit is connected via the included Null Modem cable, run the Graphic User Interface (GUI) by double clicking on the application icon. You will see the ZonePro Designer window open with an icon of the ZonePro™ unit. Double clicking on the unit will open the unit to the program screen where you will be able to see the processing modules and the configuration. If the computer cannot connect to the ZonePro device, check the COM port assignment under Network Properties in the Venue View, and make sure that you are connecting to the correct COM port.

The ZonePro Designer GUI provides a mechanism for creating scenes and device files while not physically connected to a ZonePro unit. To work off-line, open the GUI, select DEVICE then select ADD. At this point you will be prompted to choose a 640 or 641. Once the unit has been inserted into GUI you can proceed to configure, edit, create scenes, and save ZonePro device files.
Configuration of the ZonePro is done from the Configuration Wizard and allows setup of the inputs and outputs along with selection of their processing modules, zone controller setup, sig­nal routing, and front panel setup. For a detailed operation description see "The Wizard" sec­tion 3.1.
To edit a processing module, double click on that module. Adjust the module to taste; make sure that the module is engaged. This is usually indicated by the module ON button in the upper left corner of the parameter section. Although process editing is done in real-time, the changes can either be discarded or accepted by selecting the OK or CANCEL button. The following screen shot shows the example of the Output Delay module. Parameters can be copied and pasted between like modules in the ZonePro GUI. From the program screen either right click on the module and select Copy, or select Edit and Copy from the Menu Bar to Copy parameters. To past either right click and select Paste, or click on Edit Paste from the Menu Bar.
