Description
The STN Atlas / Lyngsø Marine MXM401 (Part Number 271.130 436/E) is a specialized Multiplexer Module designed for shipboard automation and monitoring networks. This module serves as a critical communication node, aggregating multiple data inputs from various sensors, instruments, and sub-systems, and consolidating them into a single high-speed data stream for transmission across the vessel’s central control bus. By enabling high-density data handling, the MXM401 significantly reduces cabling requirements while ensuring that engine performance data, alarm states, and navigation signals are delivered reliably to the central processing units (e.g., in Lyngsø Marine’s Damatic or similar automation systems).

Important Implementation Note: The MXM401 is configured via specific channel mapping. When replacing this module, it is imperative to ensure the module’s “address” is set correctly (via internal jumpers or software configuration). Because this unit is part of a high-speed data backbone, incorrect addressing or configuration can result in a “Node Not Found” or “Bus Communication Error” across the entire automation system.
