Based on the Intel Atom quad core processor E3950 (up to 2.0GHz), the nROK 6222-GCIoT meets the stringent EN50155 standard in a rugged, fanless, and compact mechanism. With a built-in CAN BUS 2.0B interface, the nROK 6222-GCIoT provides complete communication capability between train and computer. The nROK 6222-GCIoT is equipped with intelligent power management and can be remotely turned on via ignition, RTC timer, or SMS message. To connect with IP cameras, the nROK 6222-GCIoT has 4 x 802.3at/3af (Max. 60W) PoE ports. The 2.5" removable SSD and SD memory card design facilitates storage access. nROK 6222-GCIoT maintains flexibility in order to meet the demand for video surveillance in train applications. Furthermore, an attachable VTK6222-PK power isolation kit protects the nROK 6222-GCIoT from unexpected power surges.
