Monitoring System 500T

Didactum Monitoring System 500T – Professional IT Monitoring System for Server Rooms, Technical Centers, and Critical Infrastructures

The Didactum Monitoring System 500T is a state-of-the-art, field-proven solution for the continuous monitoring of mission-critical rooms and facilities. It was specifically developed for administrators, facility managers, and security engineers who require a reliable, scalable, and autonomous platform for monitoring their IT and infrastructure environments. This all-in-one remote monitoring system operates completely stand-alone and requires neither an external server nor additional software to collect measurements, generate alarms, or execute actions. The system architecture combines a modern ARM processor with a robust Linux-based operating system and an intuitive web-based user interface. All monitoring and control processes can thus be managed centrally, securely, and efficiently.

Whether in data centers, network rooms, energy supply facilities, or production areas, the Didactum 500T can be used across industries. It monitors physical environmental parameters, reports faults in real time, and automatically controls connected systems to prevent downtimes or secondary damage. Via integration into common SNMP-based management systems such as Zabbix, PRTG, Nagios, or Check_MK, the 500T can be seamlessly integrated into existing IT monitoring environments.

Rugged Design and Reliable Hardware Architecture

The Didactum Monitoring System 500T was designed without moving components such as fans or hard drives to maximize service life and reliability. The system is housed in a solid 19-inch metal casing and equipped with an integrated 230-volt power supply. An internal temperature sensor monitors the device’s operating temperature to prevent overheating. In this way, the monitoring system remains operational even under adverse conditions such as fluctuating room climates or industrial environments.

Comprehensive Sensor Integration – Monitor up to 64 Sensors Simultaneously

The Didactum Monitoring System 500T provides eight RJ-11 ports for analog, IP-capable sensors. In addition, the integrated CAN bus port supports connection of up to eight additional CAN expansion units, allowing the simultaneous monitoring of up to 64 sensors or digital contacts in total. All sensors are automatically detected (auto-identification) and displayed in the web interface. Administrators can assign custom names, thresholds, and alarm settings to each sensor – for example “Temperature Sensor Rack 1” or “Water Sensor Raised Floor Storage Room.”

Examples of Sensors and Typical Applications

• Temperature Sensors: Monitor ambient temperature in server rooms, racks, or network cabinets. When critical thresholds are exceeded, the 500T automatically sends alerts or activates cooling systems.
• Humidity Sensors: Measure relative humidity. If humidity becomes too high, warnings are issued to prevent condensation and corrosion damage to equipment.
• Water Sensors and Leak Detection Cables: Detect water leakage early, for example under raised floors, air conditioners, or pipes. In alarm mode, the system can automatically shut off valves or activate pumps.
• Smoke and Gas Sensors: Detect smoke or gas emissions in technical rooms before fire alarm systems are triggered. Ideal as early warning systems in data centers or laboratories.
• Vibration Sensors: Detect shocks caused by tampering, vandalism, or mechanical faults.
• Door Contacts, Motion Sensors, and Glass Break Detectors: Provide protection against unauthorized access and are an essential component of physical IT security.
• Power and Voltage Sensors: Monitor UPS systems, server racks, and power circuits to detect energy consumption trends, overloads, and anomalies at an early stage.

Example from Practice:

A temperature sensor detects rising heat in a server cabinet due to a fan malfunction. The 500T automatically sends an email and SMS alarm, simultaneously activates a backup fan via relay, and forwards an SNMP trap to the central monitoring system. Once the temperature normalizes, the relay is deactivated automatically, and the event is recorded in the Syslog. This form of automated fault handling prevents downtime and protects sensitive equipment against heat damage.

CAN Bus Expansion and Modular Scalability

For larger monitoring architectures, the 500T offers modular expansion via the CAN bus. Each connected CAN unit supports up to eight additional sensors – such as temperature, humidity, smoke, or airflow sensors. The CAN bus can extend up to 305 meters, enabling coverage of entire buildings. A typical application includes monitoring multiple technical rooms in a single facility, where all data converges into the 500T web interface.

Intelligent Logic and Automated Reactions

The Didactum Monitoring System 500T features a built-in logic engine that enables users to define complex conditions and responses. By combining sensor states, schedules, and triggers, intelligent automation rules can be configured.

Example:

“If server room temperature rises above 28 °C AND humidity drops below 30 %, activate Fan 1, send an email to the IT manager, and set the AC to level 2.” Such combined logic can be enhanced with timers and escalation stages to facilitate multi-level alarm and response behavior.

Another Example:

A leak is detected by the water sensor beneath the air conditioning unit. The system immediately triggers an alarm, activates a connected pump via relay, and sends an SMS notification to the facility manager. All events are logged for complete transparency and root-cause analysis.

Comprehensive Alarm and Notification System

The Didactum Monitoring System 500T supports numerous alarm types – from email alerts and SNMP traps to SMS notifications using the optional LTE modem. Administrators can freely define which sensors trigger which recipients and channels. Macro functions enable personalized messages containing live data and timestamps. In case of network failures, communication can continue through the cellular network, including receipt and execution of remote SMS commands (e.g., to switch relays or restart devices).

All communication is based on standard protocols such as DHCP, HTTPS, SNMP v1/v2c/v3, SMTP, FTP, RADIUS, SYSLOG, and TLS. Every event and alarm is timestamped and recorded within the system log, guaranteeing a complete audit trail that supports documentation for internal or external compliance reviews.

Integrated Data Logger and Long-Term Analytics

The integrated data logger continuously records and analyzes all sensor metrics. Temperature profiles, humidity trends, and voltage levels are displayed in real time through the web interface. Data can be exported as CSV or XML files for use in analysis software such as Microsoft Excel or Power BI. Storage can be expanded via a USB memory stick for long-term tracking of trends over months or years—essential for energy efficiency reports, maintenance records, and compliance audits.

LTE Communication and Remote Management

For locations with limited internet connectivity, the 500T can be equipped with an LTE modem, ensuring uninterrupted communication through mobile networks. Administrators can send commands via SMS—such as rebooting systems, toggling relays, or activating sensor groups. Each command receives a confirmation message to ensure reliable execution. In unmanned remote sites like wind turbines, broadcast stations, or pumping facilities, this offers a major advantage for operational safety.

Building and Infrastructure Monitoring with the Didactum 500T

The Didactum Monitoring System 500T is not limited to IT monitoring. It can also be used in building infrastructure management to supervise climate control, backup power, fire detection, or access control systems. Four potential-free inputs allow integration of external equipment such as UPS units, HVAC systems, or sprinkler systems. For example, if a UPS fault occurs, the system sends a corresponding SNMP notification or SMS alert to the maintenance team.

In practice, an entire facility can be digitally controlled: temperature and humidity sensors monitor indoor climates, door contacts secure restricted areas, leak sensors detect water intrusion, and power sensors track energy consumption. All information is centrally collected within the 500T and displayed in real time on customizable dashboards. Thus, the Monitoring System 500T becomes the heart of smart building and Industry 4.0 monitoring solutions.

Practical Automation Examples

• Temperature Control in Server Rooms: When temperature exceeds 30 °C, the system automatically activates fans and notifies administrators. Once the target temperature is reached, the relay switches the cooling off again.
• Leak Detection: A water sensor detects leakage, triggers a pump, sends email and SMS notifications, and disables air conditioning to prevent further damage.
• Security Monitoring: When a door is opened during “night mode,” the system activates sirens and warning lights and captures images using connected USB cameras.
• Power Failure Management: If a voltage sensor detects a mains failure, the system automatically starts the backup generator and sends a notification to the control center.
