RTCU LX5 eco - Professional M2M/IIoT Gateway


The RTCU LX5 eco is a more economical version of the full-featured RTCU LX5 pro, with the differences summarized in the table below:

With the LX hardware architecture, the RTCU LX5 eco offers an unprecedented balance between price and performance and is at the same time positioned for a broad range of automotive and industrial Internet of Things applications.

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 without changes.

The RTCU LX5 eco 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 LX5 eco device is designed from the ground up for professional M2M / IIoT applications with strong onboard I/O capabilities and multiple communication interfaces such as LTE Cat.1, CAN bus, RS232, RS485, and 1-Wire.

The RTCU LX5 eco is designed for the most advanced automotive applications as well as the most demanding industrial applications and is therefore available in two versions - one designed for DIN rail mounting.  The onboard I/O system can be expanded almost indefinitely with Modbus I/O extension modules.
