Technical FAQ
Q1: How do I choose an in-vehicle computer for fleet management and passenger information systems?
A: An in-vehicle computer should be selected based on processing requirements, display outputs, vehicle connectivity, wireless communication, power architecture, and environmental conditions. For fleet management and passenger information systems, features such as multi-display support, CAN bus, serial communication, WWAN/GNSS expansion, wide-voltage input, and ignition control are particularly important. The VBOX-3123-R2312 combines these capabilities in a fanless platform designed for transportation deployments.
Q2: Can the VBOX-3123-R2312 drive multiple displays for passenger information and in-vehicle HMI applications?
A: Yes. The VBOX-3123-R2312 provides two HDMI® outputs supporting up to 4K@60Hz and one DVI-D output, powered by integrated AMD Radeon™ Graphics. This allows system integrators to drive up to three displays from a single computer for applications such as passenger information, digital signage, driver HMI, and operational dashboards.
Q3: How can the VBOX-3123-R2312 integrate with vehicle networks, sensors, and onboard devices?
A: The system provides four configurable RS-232/422/485 ports, digital and analog I/O, USB, dual GbE, and optional CAN bus connectivity for integrating vehicle networks, sensors, controllers, displays, and other onboard equipment. This enables the VBOX-3123-R2312 to serve as a central computing and communication hub for fleet management, transit monitoring, and other in-vehicle systems.
Q4: How does the VBOX-3123-R2312 support 5G/LTE, GPS, and remote fleet connectivity?
A: The VBOX-3123-R2312 provides dedicated expansion for WWAN, Wi-Fi/Bluetooth, and GPS, including an M.2 B-key interface for 5G/LTE modules with dual SIM support. This allows vehicle location, operational data, and sensor information to be processed locally and transmitted to fleet management or back-office systems. Dual SIM capability can also provide deployment flexibility when vehicles operate across different cellular networks.
Q5: How does the VBOX-3123-R2312 protect data during unexpected vehicle power loss?
A: In addition to its 9–60V DC input, ignition management, over-voltage protection, and reverse-polarity protection, the VBOX-3123-R2312 supports an internal battery backup unit that provides approximately 10 minutes of temporary operation, depending on system power consumption. This gives applications additional time to preserve critical data or perform a controlled shutdown when vehicle power is unexpectedly interrupted.
