Function and Purpose
The Didactum PDU 4M remote-managed, switched, and per-outlet metered PDU is a compact unit with 4 outlets, 110/240V. Each of the four IEC-320 C13 outlets of this power distribution unit can be independently controlled (On / Off / Reset / Toggle) and measured.
Electrical parameters (voltage, current, power, frequency, active power / real power, active energy / real energy) are measured with high accuracy at each outlet. The device features a LAN port (and a built-in Ethernet switch) for connection to a LAN. Each output supports zero-cross switching to protect connected equipment.
The outputs can be controlled via the device’s web interface, a mobile app, or various M2M API protocols (REST API, SNMP).
Main Features:
Environmental Monitoring: A CAN port allows connecting digital CAN sensors and CAN extensions in series to continuously measure important environmental factors, thus ensuring optimal conditions that prevent equipment damage and operational disruptions.
Flexible Configuration: Users can manage up to 24 CAN devices and 300 different elements, including notifications, triggers, timers, and logic schemes, enabling customized monitoring solutions.
User-Friendly Interface: The integrated web interface provides access to virtual sensors, logic schemes, and various notification types, simplifying user interaction and enhancing accessibility.
Remote Connection: The mobile-friendly web interface allows easy management and monitoring of all outlets and sensors.
USB Camera: Captures a JPEG stream during alarm events.
Logs: SDHC or SDXC memory cards up to 512 GB allow data storage for up to 5 years.
Functions:
1. DC 12V POWER - Keeps the circuit board running and enables sending alarm notifications when the main C14 inlet loses power supply.
2. Chassis Grounding - Chassis grounding, M4 thread.
Improves equipment immunity against conducted and radiated RF interference. Please contact a professional electrician before connecting it.
3. INLET FUSE - 10A 5x20mm
4. INLET - C14 inlet, 110-240V AC, 50/60Hz, fuse 10A 5x20mm
5. OUTLETS 1-4 - x4 C13 sockets 110-240V AC, 50/60 Hz.
6. TEMPERATURE SENSOR - Accuracy +/- 1 °C
7a. Factory reset - Reset settings to standard factory defaults.
Hold the button pressed for more than 5 seconds. The ERR LED starts blinking. This indicates the factory reset has been initiated. Wait 20-60 seconds for the system to restart.
The ACT LED starts blinking once the system has restarted. The device is now accessible.
7b. Restart - The button restarts the device. Hold the button for 2 seconds and then release it; the system will restart.
8a. R1, R2, R3, R4 - LED status indicators for the status of x4 C13 outlets.
LED ON (orange) - the relay is ON (the initial state can be configured).
LED OFF (off) - the output is OFF (the initial state can be configured).
8b. LED: ALARM - The LED can be programmed via the user interface for alarm indication.
8c. LED: ERR - Red LED indicates errors and traffic.
Device operating mode: If everything is normal, the LED is off; otherwise, it is constantly lit.
Software update mode: flashes at a rate of 2 times per second;
8d. LED: ACT - Green LED shows the device system status,
Device operating mode: flashes at a frequency of 2 times per second;
Successful completion of the software update process: flashes at a frequency of 4 times per second;
9. CAN - Digital RJ12 6P4C connector for connecting CAN sensors/extensions/devices on a CAN bus.
Modules can be connected in series.
LED: CAN - Green LED indicates CAN bus status.
LED blinks slowly - nothing is connected
LED blinks quickly - configuration in progress
LED is constantly on - connected to CAN devices
10. LAN port - Ethernet 10/100 Base-T port, provides an Ethernet connection.
Orange LED - the orange LED is for the Ethernet port. Indicates network traffic.
Green LED - green LED for Ethernet port. Indicates network traffic. Blinks green during system startup. Shows connection status (solid green light - connection established, blinking green - attempting to connect).
11. SD card - MicroSD card slot with eject mechanism. The card is needed for data storage or "system recovery".
12. Dip switch N… R
Normal mode: The switch is set to the left ←. The switch should always be in this position.
Device recovery: The switch is set to the right →. Used to load the clean system image from an SD card.
13. USB - Micro-USB 2.0 port is used for USB camera recording, USB flash for system logs, and system recovery.

Areas of Application
The web interface offers users a powerful and intuitive platform to manage and monitor the device, outlets, and sensors. It is user-friendly while also providing advanced features for real-time control and automation.
The web user interface is integrated into every Didactum PDU and can be accessed via an IP address.
Main Features:
Outlet management, monitoring, and switching: Easy control of outlets, monitoring of values, and manual switching on and off of outlets or via logic schemes.
Dashboard overview: Users can monitor live data from outlet parameters, sensors, and devices, providing immediate insights into environmental conditions, energy systems, and other critical parameters.
Customizable alarms and notifications: Alarms can be configured to trigger notifications via email, SNMP trap, HTTP request, or web-to-SMS.
Logic schemes: The interface enables users to create logical automation schemes to automate actions based on specific triggers (e.g., server reboot in response to a PING).
Historical data & logs: Access to detailed event and sensor data logs that assist in system audits, performance analysis, and troubleshooting.
Multi-user access: Provides various permission levels for multiple users to ensure secure and organized team management.
Remote management: The web interface is remotely accessible, allowing users to manage and monitor systems from anywhere.
Mobile device optimized: The web interface is optimized for mobile devices and tablets and can be viewed and controlled from any mobile browser.
