Welcome to the latest news from Logic IO!

This newsletter is the biggest news from Logic IO for the last 10 years! This is really no exaggeration, as this is the culmination of years of development, that now materializes!
We are today launching the new RTCU NX-400 Professional Industrial M2M/IoT Device that rests on an entirely new hardware and software architecture, which are destined to define all future products from Logic IO!


The RTCU NX-400 is a powerful M2M/IoT Gateway device, that rests on an entirely new hardware and software architecture representing a major leap in functionality, power, openness and performance. The RTCU NX-400 has been designed for the most demanding M2M and Internet of Things applications, that demands the absolutely most advanced product available on the market.

The device is based on the new NX32L (NX32 for Linux) architecture, that embraces many new technologies and at the same time maintains full backward compatibility, that ensures already implemented and tested NX32 applications can execute without changes.

The RTCU NX-400 device has been 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-400 device is an industrial DIN rail device, that has been 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 Penta-band UMTS, Wi-Fi, Bluetooth Classic / Low-Energy, CAN bus, Ethernet, dual RS232, dual RS485 and 1-Wire.

The RTCU NX-400 also sports an USB host port interface allowing expansion of the device with accessories such as: GPS, RFID reader, additional Ethernet port and additional RS232/RS485 ports.
