The software consists of three parts: • configuration software, is installed in the network controller, the diagnosis and record the software, is installed in the network controller, can also choose to install on the record of PC software, file transfer, installed on the configuration of the PC, with the network controller provides an overview of the system configuration software Each system must use configuration software. After configuring data items through the PC and downloading them to the network controller, the system can disconnect the PC and run independently. Configuration software is required only during installation and when changing the configuration of an existing system. The configuration software is easy to use, and even first-time users can browse the configuration easily. The main function of diagnostic and recording software is to monitor and record the status of all components of the PA system. The software records all events (for example, call and system component state changes) and displays the current state of the system. It provides real-time recording to the PC. File transfer software file transfer software is used to transfer data and information files from a PC to a network controller. The basic function configuration software software supports three levels of access: administrator, installer, and user. Each level has different access rights. Call macros allow users to configure different functions and/or operations that can be assigned to input (for example, control input and call station buttons). The same call macro can be assigned to multiple inputs. The call macro defines the following: priority, start and end voice, audio input, sequence of information or information, number of repetitions, and schedule with duration and interval, etc. The zone grouping feature enables users to define areas that contain similar locations. In regional configurations, region-related items such as amplifier channel output, audio output, and control output can be assigned to defined areas. The main power amplifier can be connected to the standby power amplifier, and when it fails, it can be switched to the standby power amplifier automatically. The ratio of the main power amplifier to the standby power amplifier can be set flexibly to meet the specific application requirements. The software can configure the input and output of all devices in the system. All audio has entered and output audio processing capabilities, including through high-pass and low-pass filter parameters of input and output are balanced, and only the input gain and the limit of radial adjustment. Audio input can be set to a microphone or line. Each amplifier output can be configured with a separate delay time. The system will automatically adjust the level of 20 kHz pilot tone. The buttons on the call station keyboard can be assigned different functions. A call station can be defined as an emergency call station, allowing you to add a region or audio output during broadcast. Users can configure a range of functions for control input. After configured, control inputs can monitor whether the lines they connect are open and short-circuited. The zone can be configured with a variety of time-based volume Settings. Background music source can be assigned to music channel, while music channel can be assigned to different regions/audio output. Diagnostic and recording software the software supports query modes including routine events, call records, and fault records. Through this function, the fault state of all devices and any state change in the system can be monitored. Users can view the latest 200 failure messages stored on the network controller. Control input can be used to report the failure status of third-party devices that are not part of the Praesideo system, so users can look up the recorded events of monitored external devices. In addition, the software can control sound and visual failure indicator lights. When the user confirms and restores the fault and alarm status, the software will record the confirmation and reset operation of the user's holding line. In addition, events from multiple systems can be stored in a database using a pc-based recording service. Users can access the database remotely through a dedicated Praesideo log viewer program. File transfer software file transfer is protected by user ID and password. For groups of information that must be stored in the network controller (a collection of multiple wav files), the user can compose and store them on a PC and send them to the network controller. Configuration files created in offline mode can also be transferred to the network controller. In addition, the user can retrieve configuration files in the network controller.
