The V2406C computers are compliant with EN 50155:2017 and EN 50121-4 for railway onboard and wayside applications. Designed for heavy-duty data processing tasks, the V2406C computers are built around an Intel® Core™ i7/i5/i3 or Intel® Celeron® high-performance processor and come with up to 32 GB RAM, one mSATA slot, and two hot-swappable HDD/SSD for storage expansion. For reliable connectivity in train-to-ground (T2G) applications, the computers are provided with two mPCIe wireless expansion slots and four SIM-card slots. These help establish redundant LTE/Wi-Fi connectivity, ensuring solid bidirectional communications between a fast-moving train and the wayside applications. In addition, preinstalled QMA cable for wireless modules can help reduce assembly efforts and ensure low RF leakage. For connecting with onboard and wayside systems and devices, V2406C computers are equipped with a rich set of interfaces including 2 Gigabit Ethernet ports, 4 RS-232/422/485 serial ports, 6 DIs, 2 DOs, and 4 USB 3.0 ports. In addition, the V2406C computers provide 1 VGA video output and 1 HDMI output with 4K resolution support.
