Prevost Liaison 2.0 offers more reliable communications, efficient data transfer, advanced features and an easier to use interface. The system now uses a cellular network to improve signal reliability and provide wider coverage. More efficient data transfer results in more data sent more often. Reporting is possible every five minutes and “Fault Alerts” are provided in real time, allowing for a more representative status of the vehicle. Fault Alerts, which can be customized by vehicle type, also display current hardware and software installed in the vehicle, for faster and easier troubleshooting.
