Intel Atom ® quad-core processor E3950 (up to 2.0 GHz), the nROK 6222-GCIoT is particularly compliant with the strict EN50155 standard in a rugged, fanless and compact mechanism. The nROK 6222-GCIoT provides full communication capability between the train and the computer with its built-in CAN BUS 2.0B interface. Equipped with smart power management, the nROK 6222-GCIoT can be woken up by ignition, RTC timer or remote SMS message. The nROK 6222-GCIoT supports 4 x 802.3at/3af (Max. 60 W) PoE ports to connect to IP cameras. The design of the 2.5" removable SSD and SD memory card helps provide easy access to storage. The nROK 6222-GCIoT retains the flexibility to meet the demand for video surveillance in train applications. Moreover, the nROK 6222-GCIoT is protected against sudden power surges via a pluggable VTK6222-PK power isolation kit.
