OVERVIEW:

The DURION-ER02 is a compact stand-alone high reliability AVL/AVM gateway for bus and tram applications. The Quad Core LINUX application processor is available with either WRT or YOCTO Linux, depending on the target application.

The compact footprint makes the ER02 ideal for upgrade programs, which require high accuracy DR-assisted vehicle positioning, cellular connectivity as well as interfacing to the J1939 or MVB vehicle bus. A CAT1 or CAT4 MiniPCIe LTE modem provides cellular connectivity, supporting both eSIM as well as standard uSIM.

The GNSS solution is based on the high accuracy LC29H receiver, which supports operation in both UDR and ADR modes. External Wheel-tick and Direction signals can be used in ADR mode. These signals have a wide 0-30DC Input range. The ADR/UDR based positioning can reliably navigate underground or in poor satellite signal conditions assisted by the IMU based sensor data.

MVB connectivity bases on the Duagon D013 module, which provides a dual redundant isolated EMD interface. The standalone MVB interface connects to the application processor’s serial port.

A build option to support Stereo Audio is available. The Line level Stereo output uses the connector pins dedicated for the second CAN port and the differential MIC signals occupy the Wheel-Tick and Direction signals. These options are mutually exclusive due to pin sharing.
