CB-V120-U46 adds a smart card reader, a third USB Type-A port, and an RS232 serial port to a configured Getac V120 fully rugged laptop. This factory upgrade applies to the V120 and is not a standalone device. It supports deployments that need smart-card access alongside a dedicated serial connection. The V120 has a 12.2 in WUXGA capacitive multi-touch LumiBond display rated at 1,000 nits, Wi-Fi 7, Bluetooth v5.4, and 10/100/1000 base-T Ethernet. Its standard I/O includes two USB 3.2 Gen 2 Type-A ports, two Thunderbolt 4 Type-C ports, HDMI 2.0, LAN, audio combo, DC input, and a docking connector. The platform is MIL-STD-810H, MIL-STD-461G, and IP66 certified, with resistance to vibration and 4 ft (1.2 m) drops. Use this expansion for ambulance, fire and rescue, policing, utility asset management, industrial programming, and robotic control environments where smart-card access and serial equipment connections are needed. For a configured V120, CB-V120-U46 selects this integrated expansion combination.
