 The new RTCU NX-900 and RTCU MX2 turbo LTE!

Just before the end of this decade, we are pleased to announce two new products.
The new RTCU NX-900 is in the same family as the popular RTCU AX9 turbo, but based on the powerful NX32L architecture, it brings a long list of new features and capabilities.
Our undisputed bestseller, the RTCU MX2 turbo, is now available in an LTE version making this device future-proof and ready for tomorrow's applications.


The new 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 combines the form-factor, power, and I/O architecture from the popular RTCU AX9 turbo with the power and advanced NX32L features from the RTCU NX-400!

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 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 on-board I/O system can be expanded almost indefinitely and completely transparently by adding Modbus I/O modules.
