A2B Bus Monitor - Level 1 Application

Interested in participating in the beta release? Send an email to sales@totalphase.com. 

Please note, this is an application that requires installation on the Promira™ Serial Platform.

Total Phase’s A²B Bus Monitor - Level 1 Application provides unprecedented access to the A²B system. By attaching the A²B Adapter Board in-line between A²B nodes, the A²B monitor can non-intrusively sniff A²B data on the line, giving users a real-time view into A²B traffic on the bus. A²B superframes are decoded and disassembled into I2S/TDM audio data and I2C control data for easy debugging. Additionally, full reporting on Interrupts and GPIO handshakes are correlated into the data capture.

The A²B Bus Monitor - Level 1 Application provides multiple ways of viewing the (A²B) data. Besides the traditional Bus Data view, the application also offers a Node Topology view and an Audio Channels view. The Node Topology view allows quick visualization of all nodes on the (A²B) bus. Users can display and export all node configuration settings to validate node initialization.

The Audio Channels view allows users to diagnose audio channel problems. Real-time audio levels for all upstream and downstream channels are displayed and audio for multiple upstream or downstream channels can be mixed and monitored simultaneously to quickly identify I2S/TDM data slot mismatch problems. Audio data can be exported to a file for further analysis using audio analysis software.

The A²B Bus Monitor - Level 1 Application requires the Promira® Serial Platform and takes advantage of its high performance serial data communications over USB or Ethernet. Data capture and analysis happens on the device, which allows for remote data capture and later review. The A²B Bus Monitor - Level 1 Application is a compact solution excellent for bench top prototyping and in-vehicle field testing.

The purchase of your A²B Bus Monitor Application includes one year of support, allowing you to download any updates for this application for 12 months after purchase.
