Introduction
The RTCU LX2 pro is a powerful successor to the RTCU MX2 turbo with significant features,
capacity, power and security improvements. The RTCU LX2 pro is based on the latest LX hardware
architecture, offering an unprecedented balance between price and performance
The RTCU LX2 pro is positioned for a broad range of professional Automotive Internet of Things
applications. With onboard Worldwide LTE Cat. 4, Dual-band GNSS, and BLE 5.3, the RTCU LX2
pro device is ready for tomorrow's advanced IoT 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 that already
implemented and tested NX32 applications can execute without changes.
The RTCU LX2 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 LX2 pro has an onboard Dual-band Multi-constellation GNSS positioning engine that
supports the concurrent reception of all four global GNSS systems. The Dual-band receiver tracks not
only L1 but also L5, significantly mitigating the multipath effect in an urban environment - ultimately
improving positioning accuracy substantially. The RTCU LX2 pro is also available in versions with
Dead-Reckoning and RTK.
This manual contains technical documentation covering the installation and usage of the RTCU LX2
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.

External Connections
Connections to external equipment are made via the connectors located on the back and front of the
RTCU LX2 pro.
The front panel is equipped with connectors commonly accessed by the user: SIM-Card, DIP-switch,
Service/programming port, LED's, RS232 and the reset button. Additionally, the configuration DIP-
switches are placed directly behind the front panel.
The back panel holds all connectors necessary for installation: 4-pin (X1) power and ignition, 6-pin
(X4) for RS232 and CAN, 12-pin (X2) for different communication interfaces and a 16-pin (X3) for
analog and digital I/O. Connection to the cellular antenna is via an SMA(F), connection to a 3V active
GNSS antenna via an SMA(F), and connection to the Bluetooth antenna via an RP-SMA(F) connector.
