Connections & Controls
All ports, buttons, and LEDs on the front, rear, and side panel of the 50T at a glance.
All sensor and network connections are deliberately distributed across three sides of the housing: the front houses the connections for daily operation – USB, the four analog sensor ports A1–A4, the SD card slot, and the status LEDs. The rear holds the network, relay, and power supply connections. The "N/R" toggle switch on the side is intended exclusively for system recovery via SD card and should always be set to "N" during normal operation.
Front view
Front view: USB, analog sensor ports A1–A4, SD card, status LEDs.
USB
Micro-USB 2.0 port – for USB camera recording as well as USB flash for system logs, upgrades, or restoring factory settings.
Analog sensors A1–A4
4× RJ12 6P4C connectors for analog sensors with automatic detection (AutoSense).
SD card
MicroSD card slot with ejector – for data storage or system recovery.
Status LEDs (R1/R2, ACT, ALARM, ERR, CAN)
R1/R2 indicate the status of the two 12V outputs. ACT (green) shows the system status, ERR (red) indicates errors or an update in progress, ALARM is freely programmable, and CAN (green) shows the bus status – slow blinking: nothing connected, fast blinking: configuration in progress, solid light: devices connected.
Rear view
Rear view: relay, restart/reset, LAN, CAN, dry contacts, power supply.
Relay 12V / 0.25A
Output terminals (electronic relay), 3.81 mm pitch, 3-pin, each with its own status LED (E1/E2).
Restart button
Hold for 2 seconds to restart the device.
Reset button (factory settings)
Hold for longer than 5 seconds – the ERR LED starts blinking, and after 20–60 seconds the device is reset and accessible again.
LAN port
10/100 Base-T Ethernet with two status LEDs: orange indicates network traffic, green indicates connection status (solid = connected, blinking = establishing connection).
CAN
Digital RJ12 6P4C connector for CAN sensors, expansions, and devices, daisy-chainable, with its own status LED.
Dry contact inputs 1–2
Digital inputs, 3.5 mm pitch, 6-pin.
DC 12V power
Main power input, 12V DC / 2A.
Side view
Side view: toggle switch for normal operation and system recovery.
Side switch N/R
"N" normal operation (default position, always to the left). "R" loads a clean system image from the SD card for a full system recovery.

Frequently Asked Questions
What is the Didactum Monitoring System 50T and what is it used for?
The Didactum Monitoring System 50T is a professional monitoring solution for IT infrastructures and critical environments. It continuously monitors important parameters such as temperature, humidity, smoke, motion, door contacts, and other sensors. The system is primarily used in server rooms, data centers, warehouses, and other business-critical areas to prevent outages and provide timely warnings of problems.
Which sensors can be connected to the system?
The Monitoring System 50T supports a wide range of smart sensors via Didactum's proprietary sensor network – including temperature, humidity, smoke, PIR motion, door, vibration, water, and voltage sensors. Up to 100 sensors can be monitored simultaneously.
How are alarms and notifications sent?
The system offers various alerting methods: email notifications, SMS, SNMP traps for network management systems, syslog messages, and push notifications via the mobile app. External sirens or beacons can also be connected. Alarm rules are individually configurable with various thresholds and escalation levels.
Can the system be integrated into existing IT infrastructures?
Yes. The system supports SNMP v1/v2c/v3, can be integrated into common monitoring platforms such as Nagios, PRTG, or Zabbix, and has a REST API for custom integrations. It connects via Ethernet and can be managed both through the web interface and via network management tools.
How do you connect and commission the system for the first time?
Connect the device to your network via Ethernet and plug in the 12V DC power supply. The system starts automatically and can be accessed via a web browser at the default IP address 192.168.0.193 (or .101 or .62). The setup wizard guides you through basic configuration (network settings, admin password, time zone). Sensors are automatically detected as soon as they are connected to the RJ12 sensor ports. The "Didactum Manager" helps with advanced configuration and setting up alarm rules.
What power supply does the system require, and how reliable is it?
The Monitoring System 50T is powered by an external 12V DC power supply. All events are permanently logged, and a built-in watchdog ensures automatic restarts in the event of system errors. Redundant network connections can also be configured.
