The A²B Bus Monitor System is a powerful debug tool that provides unprecedented insights into the network traffic on an A²B technology-based audio network.
The A²B Bus Monitor System is a combination of a compact, professional-grade, single-unit hardware device, and an easy-to-use host application software.
The A²B Bus Monitor acts as a spy node in a daisy-chained A²B based network, to non-intrusively monitor, and capture, data from the bus. All forms of traffic; audio and control, can be logged live over USB and Ethernet. Key actions such as those occurring during an A²B network discovery process can be captured and deconstructed for detailed analysis. In addition, up to two channels of A²B audio can be listened to in real-time through the PC speakers by simply clicking on the channel’s corresponding VU meter bar in the audio slot view.
All logged A²B events and triggers are color-coded and can be filtered for easy management and interpretation. Detailed, slave node-level information complete with register settings helps with increased debug capability. The ability to import project session files (.ses) created using the A²B Analyzer application software greatly helps with overall network awareness, and empowers users to not only setup quickly, but also thoroughly understand their systems.
All captured information is time-stamped, and a custom log viewer allows users to view perfectly time-aligned audio signals with I2C commands and trigger instances. This time-aligned view results in greater visual comprehension of the entire network; a powerful capability in debugging complex A²B systems. In addition, real-time access to audio from the individual channels accelerates the overall analysis process.
The A²B Bus Monitor PRO is ideally suited for automotive OEMs and Tier 1s developing A²B technology-based systems and components. With robust, compact hardware that supports both USB and automotive power and ignition, the device can be used on-bench, as well as inside car cabins, to capture data from test drives. An optional custom in-car power cable is available to facilitate this.
