DURION-ER03 Integrated Computer and Dual 5G MIMO Railway/Bus Router

Bangkok - October 16th, 2023 - Launched at BusWorld 2023 exhibition, the DURION-ER03 redefines high performance in-vehicle routers with its unique internal architecture. The ER03 combines three processors, each with dedicated functionality. The core router is based on the NXP Layerscape LS1046A networking processor, supporting this CPU is a ARM CORTEX A7 Linux application processor, which connects to the router using an internal Ethernet interface. A dedicated CORTEX M0 microcontroller manages and supervises the device operation and provides I/O interfaces such as J1939 CAN, universal CAN 2.0, RS-485 and Digital I/O.

ER03 enables execution of application software on a separate CPU, software can be updated individually without affecting the other. Th router is based on Embedded WRT LINUX, while the application processor can use ANDROID or any other LINUX flavor. Specific data security enhancing or encryption SW can be executed on the LINUX platform.

The ER03 features 4+1 GBIT Ethernet MAC with RJ45 connectors as well as two Ser-Des SFP+ ports, which can accept 10GBit Copper/fibre or 1000Base-T1 Automotive Ethernet SFP adapters. Two M.2 5G modems with eSIM and uSIM support interface directly to the router processor over USB 3.0/PCIe 2.0. An additional internal M.2 expansion port is available for SATA SSD, MVME SSD (1-lane PCIe) or high speed WiFi.

A high accuracy GNSS receiver supports both UDR and ADR assisted navigation. In ADR mode, the receiver uses speed and direction data extracted from the J1939 bus or from train systems over Ethernet. Standard interfaces, such as general portpose CAN 2.0, 2x RS-485 and Digital I/O, are available. Furthermore, the CORTEX A7 application processor provides a DVI-D display interface and full audio I/O.
