Introduction
The RTCU NX-900 is the most advanced industrial IoT Gateway product available on the market
today.
The device is based on the 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 with no changes.
The RTCU NX-900 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-900 device is an industrial-grade device that is designed from the ground up for
professional M2M / IoT applications with its strong on-board I/O capabilities and multiple
communication interfaces such as World-wide cellular LTE, WLAN, GNSS, Bluetooth Classic /
Low-Energy, Ethernet, dual RS232, dual RS485, and 1-Wire.
The on-board I/O system can be expanded almost indefinitely and completely transparently by
adding Modbus I/O modules.
The RTCU NX-900 is, to a certain extent fully software and hardware compatible with the RTCU
AX9 turbo.
The advanced power-management features on the RTCU NX-900 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-900
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.
