Introduction
The RTCU LX4 pro is a powerful successor to the RTCU DX4i pro with significant improvements in
features, capacity, power, and security. In addition, the RTCU LX4 pro is based on the latest LX
hardware architecture, offering an unprecedented balance between price and performance.
The RTCU LX4 pro is positioned for a broad range of professional industrial Internet of Things
applications. With onboard M-Bus / Wireless M-Bus and pulse counting inputs (S0), it is a perfect
component in advanced Energy Management applications.
The device rests on the NX32L (NX32 for Linux) architecture that 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 LX4 pro device has been designed to meet the ever-increasing security challenges. 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 LX4 pro can also operate as a secure and intelligent industrial router/firewall for LAN side
clients connecting to the Internet over the cellular interface.
This manual contains technical documentation covering the installation and usage of the RTCU LX4
pro device. For detailed information on the product's programming and software configuration,
please refer to the RTCU IDE documentation.
For detailed information on the powerful RTCU M2M Platform, please refer to the
RTCU M2M Platform datasheet.
