Technical FAQ
Q1: What should I consider when choosing an in-vehicle computer for railway and rolling stock applications?
A: Key considerations include railway certification, power input compatibility, network connectivity, environmental tolerance, expansion capability, and installation requirements. The VBOX-3630R-M12X is EN 50155 certified and combines an isolated 24–110V DC input, M12 X-coded Ethernet, -40°C to 70°C operation, fanless cooling, and flexible wireless expansion for onboard railway applications.
Q2: Why is an isolated 24–110V DC input important for railway onboard computers?
A: Railway electrical systems can experience voltage variations, transients, and differences in ground potential. An isolated power input electrically separates the computer from the vehicle power source, helping reduce the effects of ground loops and electrical disturbances on internal electronics. The VBOX-3630R-M12X supports an isolated 24–110V DC input designed for integration with rolling stock power systems.
Q3: How can the VBOX-3630R-M12X support high-bandwidth railway network connectivity?
A: The VBOX-3630R-M12X provides four M12 X-coded Ethernet interfaces, including one 2.5GbE and three GbE ports. The locking M12 connections are designed for environments subject to vibration, while the 2.5GbE interface provides additional bandwidth for data-intensive network traffic. This configuration can support onboard applications involving network devices, video streams, operational data, and communication between connected railway systems.
Q4: How can the VBOX-3630R-M12X support redundant storage for onboard data and video recording?
A: The system provides two 2.5-inch SATA drive bays with RAID 0 and RAID 1 support, plus an M.2 2280 interface for NVMe storage. RAID 1 can mirror data across two SATA drives when storage redundancy is required, while RAID 0 can combine the drives when higher storage throughput or capacity is prioritized. The additional NVMe interface provides flexibility for separating the operating system, applications, and recorded data.
Q5: How can the VBOX-3630R-M12X support multiple wireless connections for railway communications?
A: The VBOX-3630R-M12X provides two M.2 B-key interfaces for 5G/LTE expansion, an M.2 E-key interface for Wi-Fi and Bluetooth, and Mini PCIe expansion for GPS and CAN. Dual onboard SIM sockets and multiple external antenna openings provide flexibility for configuring cellular, positioning, and local wireless connectivity according to the communication architecture.
