Logic IO, recognized as "The M2M Enabler," has maintained a position as a world leader in advanced and professional M2M technology since 1999. The RTCU M2M Platform represents a premier industrial concept, anchored by a unified software backbone that provides a seamless bridge between sophisticated hardware engineering and resilient production management. Built upon more than two decades of innovation, this integrated software and hardware ecosystem offers a sophisticated, high-performance environment for the world's most demanding applications.

This general-purpose platform facilitates the efficient implementation of a broad range of telemetry and telematics applications. RTCU products are engineered for any imaginable environment, with active deployments found underground, stationary, on the road, at sea, on the rail, and in the skies.



Every device in the modern RTCU range rests on the NX32L execution architecture, a hardened Linux-based environment that ensures software compatibility and hardware-accelerated security.
