Powered by an Intel ® Core™ quad-core processor E3950 (1.6 GHz), the nROK 6221 complies especially with the strict EN50155 standard in a rugged, fanless and compact mechanism. The nROK 6221 provides full communication capability between the train and the computer with its built-in CAN Bus 2.0B interface. The nROK 6221 has rich WLAN and WWAN wireless connectivity. With dual SIM card support per modem, the nROK 6221 allows six SIM cards to back each other up for better connection quality or extra bandwidth by software. In addition, the six SIM card and three WWAN module architecture can increase bandwidth for faster data transmission speed. Equipped with intelligent power management, the nROK 6221 can be woken up by ignition, RTC timer or remote SMS message. Combining various I/O ports, 3 x mini-PCIe, 2 x M.2 socket expandability and up to three displays via VGA and HDMI connections, the nROK 6221 retains the flexibility to meet the demands of different railway vehicle applications such as infotainment, dispatch systems, cellular/wireless network connectivity and video surveillance. The design of 3 mini-PCIe slots can address potential market demand when needed.
