Top Features of SerialMon for Real-Time Data Logging SerialMon is a lightweight, professional-grade multiprotocol sniffer and analyzer designed specifically for real-time monitoring and data logging of serial and network communications. In industrial automation, embedded engineering, and telecommunications, capturing data without altering system performance is critical. Developed by DuNovo AB, SerialMon serves as a non-intrusive diagnostics tool that allows engineers to seamlessly track, parse, and verify complex protocol interactions.
Below are the top features that make SerialMon a standalone solution for real-time data logging and industrial troubleshooting. 1. Multiprotocol Sniffing and Deep Packet Inspection
SerialMon is not just a generic COM port terminal; it is an intelligent protocol analyzer. It is engineered to automatically detect and parse highly specialized industrial automation protocols.
Industrial Protocol Support: It features built-in support for analyzing protocols such as ABB RP570 and ABB SPA-bus.
Marine and GPS Navigation: It acts as a dedicated analyzer for NMEA 0183 data streams.
Raw and Parsed Views: Users can toggle between raw byte streams and human-readable, deeply parsed packet structures to verify exactly what data is moving through the wire. 2. Chronological Event Tracking and Alarm Systems
Maintaining an accurate chronological sequence of automated events is crucial when analyzing long-term logs. SerialMon separates active data capturing into two smart diagnostic sections:
Dynamic Event Lists: This feature automatically compiles every signal value change in chronological order as it occurs in real time.
Persistent Alarm Tracking: SerialMon explicitly tracks binary signals that toggle to an error or alert state (e.g., changing to ‘1’). These alerts remain highlighted in the active interface until explicitly acknowledged by an operator, ensuring critical malfunctions are never missed. 3. Built-In Web Server for Remote Diagnostics
One of SerialMon’s most powerful, high-utility features is its native, embedded web server. This capability eliminates the need to be physically tethered to the machine under test.
Cross-Device Accessibility: By enabling the web server in the preferences menu, the software hosts a local session (defaulting to port 8080).
Remote Browser Monitoring: Anyone on the same network can access the live session via a standard web browser on a smartphone, tablet, or separate PC. From this portal, remote engineers can monitor raw packets, log data, trace active addresses, and audit system alarms. 4. Non-Intrusive “Sniffer” Deployment
Traditional diagnostic tools often require invasive dual-port rewiring or custom inline cables that introduce latency. SerialMon avoids this by functioning as a transparent software sniffer.
Software-Based Interception: It hooks directly into the operating system’s communication stack, capturing data packets traveling between a software application and a hardware RTU or gateway.
Zero System Impact: Because it operates transparently, it captures bidirectional traffic (transmit and receive streams) without adding overhead or interrupting the connection stability of critical infrastructure. 5. High-Fidelity Signal Testing to Control Centers
For engineers working on telecommunications, SCADA integration, and substation automation, ensuring correct signal delivery to centralized control centers is paramount. SerialMon simplifies end-to-end testing:
Gateway Validation: It acts as an intermediary verification layer, verifying that local industrial gateways are packaging data correctly before uplink.
Address Tracking: It correlates specific sensor register changes directly with downstream packet dispatches, saving hours of manual register mapping.

SerialMon balances a lightweight system footprint with the multi-protocol depth required by industrial and embedded automation engineers. By packaging remote capabilities like its integrated web server alongside dedicated alarm-tracking and protocol analysis tools, it provides an essential toolkit for ensuring data integrity across complex serial networks.
