Introduction
The RTCU NX-200 is the most advanced automotive IIoT Gateway product available on the
market today. Based on the successful hardware architecture from the RTCU NX-400, it features an
added range of sophisticated automotive features like a full-motion sensor suite, dual CAN bus
interfaces, Worldwide LTE, and a slick aluminium encapsulation with a clear reference to the
popular RTCU MX2 turbo!
The device is based on the new NX32L (NX32 for Linux) architecture, which embraces many new
technologies and at the same time maintains full backward compatibility, which ensures already
implemented and tested NX32 applications can execute without changes.
The RTCU NX-200 is designed to meet the ever-increasing challenges on security, in that it offers
full TLS on all major protocols and includes a hardened protected execution environment with
dual-boot and automatic fallback and recovery.
The RTCU NX-200 device is an automotive-grade device that is designed from the ground up for
professional M2M / IIoT applications with its strong on-board I/O capabilities and multiple
communication interfaces such as World-wide cellular LTE, WLAN, Bluetooth Classic / Low-
Energy, dual CAN bus, Ethernet, dual RS232, RS485, and 1-Wire.
The RTCU NX-200 also sports two USB host port interfaces allowing for the expansion of the
device with accessories such as RFID reader, additional Ethernet port, and additional RS232/RS485
ports
The on-board I/O system can be expanded almost indefinitely and completely transparently by
adding Modbus I/O modules.
The RTCU NX-200 is fully software and hardware compatible with the RTCU MX2 turbo.
The advanced power-management features on the RTCU NX-200 combined with the on-board
high-capacity Li-Ion battery allows the device to stay in a power-saving mode for a longer period
still being connected to the cellular network and capable of waking up on for example cellular
activity, change of digital inputs or a vibration sensor
This manual contains technical documentation on the installation and usage of the RTCU NX-200
device. For detailed information on the programming and software configuration of the product,
please refer to the RTCU IDE documentation.
For detailed information on the powerful RTCU M2M Platform, please refer to the
RTCU M2M Platform datasheet and the RTCU IDE documentation.
