The 500 II network monitoring device is the official successor to the 500 (1st generation). When switching to the new monitoring hardware, you will need to reconfigure the system, as direct import of the old device configuration is not supported. However, you can transfer the most important settings to the new system using copy and paste.
Analog sensors can still be used with the 500 II monitoring system. Existing smoke detectors and point water sensors older than 5 years should generally be replaced. Important: Please note that due to the significant changes to the hardware design of the 500 II system, we cannot guarantee compatibility with older sensors.
Add the potential-free/digital contacts to a custom group. The dry contacts added to a group can then be configured together as "Normally Closed (NC)".

Monitoring System 100 DC, Monitoring System 300, Monitoring System 500 DC.
Most of our remote monitoring appliances/control systems have a shallow installation depth and can therefore be installed in ETSI and ODF enclosures from leading manufacturers. The exact dimensions are specified under "Details" for each monitoring system in our online shop for infrastructure monitoring solutions.
Unless the measurement data is (remotely) transmitted to and stored in measurement data software or network management systems (NMS), each Didactum monitoring system can back up the device configuration and the measurement data stored in the data logger at intervals. This can be done locally (USB stick or SD drive (model-dependent)), as well as via email and FTP upload.
Alternatively, a USB stick can be connected to all measurement and monitoring devices and the sensor data stored there (64 GB max.).
Yes. Every Didactum monitoring system offers 3 access levels for different user groups such as IT managers, IT admins, facility managers or guests.
Didactum's monitoring hardware supports, among other things, FreeRADIUS.
DHCP is supported by all Didactum monitoring systems and PDUs. Please note that DHCP is disabled by default. To switch to DHCP (Dynamic Host Configuration Protocol), please go to "System Settings" => "Network" in the German-language web interface. Then, check the box next to "Enable DHCP".
Thanks to its 19-inch format, this monitoring device can be installed in a server rack from any manufacturer. 19-inch mounting brackets can be ordered for the other monitoring systems upon request.
All Didactum room monitoring devices equipped with a GSM or LTE modem support a dial-up function, meaning that in the event of a malfunction, a pre-defined landline or mobile phone number is dialed. Please note that voice transmission is not supported. The monitoring device can also send SMS text messages. The content of the SMS alarm can be customized.
All Didactum monitoring and control devices can use a ping command to check the availability of computer systems on a local or public network. If the Didactum IT control system receives no response, you will be notified immediately via email or SMS (via GSM/LTE modem or email-to-SMS gateway) upon request. Devices or systems connected via a relay can also be restarted if desired. The possibilities are numerous.
Simply mount the potential-free contact sensor on the 12VDC output of your fully SNMP-compatible remote control system. This sensor, part number 14103, can be found in our IT monitoring solutions shop. With this sensor, you can then switch your connected air conditioner without any potential (current) interruption.
[No. The vast majority of our corporate clients and public sector clients already have a mobile phone contract/framework agreement. A prepaid card or similar doesn't make sense in this case. Simply contact your mobile phone provider and request the SIM card that suits your needs.
As of March 2020, the IP-based measuring and monitoring devices of the 100 (DC) / 200 / 300 / 400 / 500 (DC) / 600 (DC) / 700 (DC) series can be equipped with an internal GSM or LTE modem. Simply add the desired GSM or LTE modem to your shopping cart.
Yes. The data logger's storage capacity can be expanded up to 64 GB using a suitable USB storage device. The high-end measuring and monitoring devices in the 400 / 500 / 600 / 700 series also offer a built-in SD card slot (max. 64 GB).
The measurement and recording takes place in real time.

As is well known, server, storage, and network systems installed in 19-inch racks generate a significant amount of heat. If the temperature in the server room is not measured and monitored, overheating or excessive heat can lead to problems such as:
- Unresponsive applications/programs
- Blue screen crashes
- Reduced network performance
- Temperature-related failure of HDDs and SSDs
- Reduced lifespan of IT hardware
A lack of temperature monitoring in the server room/data center can lead to increased IT operating costs. Furthermore, the risk of temperature-related IT failure is significantly higher in an unmonitored IT infrastructure.
To prevent hardware damage and costly IT downtime, a suitable IT monitoring system should always be in place. Risks and hazards arising from environmental factors like temperature, such as a sudden temperature increase in the server room or an undetected heat source in the IT rack, can be detected early and reported to the responsible technicians and IT managers via email or SMS alerts. Companies and public authorities that monitor their IT infrastructure(s) using DCIM solutions or network management systems (Nagios, check_MK, Icinga, OpenNMS, PRTG, Zabbix, etc.) receive temperature alerts as SNMP (Simple Network Management Protocol) messages.
The widely used SNMP protocol has been available in version SNMPv3 for some time. For future-proofing, the IT monitoring system installed in the server room or data center should support the encrypted SNMPv3 protocol.
Relative humidity (RH) must be continuously measured and recorded in server rooms and data centers. If the humidity in the server room/data center is too low, there is a risk of static discharge. In the worst-case scenario, an electrostatic discharge can irreparably damage the sensitive components of servers, network, and storage systems.
Conversely, excessively high humidity can promote condensation. For example, the moisture in the air (condensate) can settle on the circuit boards of often very expensive IT hardware. This can lead to electrical short circuits or corrosion.
The manufacturer Didactum offers a suitable sensor for measuring relative humidity. A combination sensor is also available for their web-based measurement and monitoring devices, allowing both temperature and humidity to be measured and monitored simultaneously.
Didactum's monitoring systems support the SNMPv1, SNMPv2c, and encrypted SNMPv3 protocols and can be integrated into automation, DCIM, measurement data analysis, and network management software. The SNMP MIB file required for integration with third-party software can be downloaded directly from the monitoring system's multilingual web interface.
A GSM or LTE modem is recommended if the infrastructure being monitored lacks a network or internet connection. Please also consider potential (V)DSL line outages or fiber optic disruptions. Mail servers (e.g., Microsoft Exchange) can also fail, making a GSM/LTE modem integrated into the monitoring system invaluable.
Important measurement data and alarm notifications can then be transmitted via the GSM or LTE mobile network. This ensures that technicians and administrators automatically receive alerts on their mobile phones/smartphones. As of October 2018, any monitoring system equipped with a GSM or LTE modem can send SMS notifications to up to 10 different mobile phone numbers.
The content of the SMS message can be customized using Didactum's comprehensive macro functions.
Information on the topic of "IT system reliability is the boss's responsibility" can be found here in the technology portal. You should list the missing IT security technology for your boss in an email.
Useful information on potential vulnerabilities in the server room can be found in the IT Baseline Protection Catalog of the Federal Office for Information Security (BSI). You might want to print out a copy of the email and take it home with you, just in case.
As of February 2019, the Ethernet-based remote control and monitoring systems of the 50 / 100 IV (DC) / 400 / 500 II (DC) series can be used in an operating environment from -10°C to +85°C at 5% to 95% relative humidity (non-condensing). Each Didactum remote control and monitoring system is equipped with an onboard temperature sensor for measuring and monitoring the internal housing temperature.
If the maximum permissible operating temperature is exceeded, you can optionally be notified via SNMP trap, email, and/or SMS (via GSM/LTE modem or email/SMS server). An alarm siren with LED flashing light can also be optionally connected to the remote monitoring system to provide an audiovisual signal indicating a critical operating temperature.
The real-time measurement data from the temperature sensors connected to the monitoring system is stored in the built-in data logger. Using the sensor graphing function integrated into the web interface, you can graphically display the temperature trend over the last minutes, hours, or days. You can view the measurement trends of individual sensors as well as multiple sensors simultaneously.
Create the necessary graphs by taking screenshots and embedding them in your reports. To export the temperature sensor measurement data, go to the "Export" tab in the "System Menu." Here you can export the sensor data from the IP Thermometer in XML or CSV format. You can then graphically process the temperature measurement data using software such as Microsoft Excel, creating charts (e.g., line graphs) or sparklines.
The measurement data contained in the CSV and XML files can also be further processed using scripting languages (including Python). The open-source tool Cacti is also a suitable option. The sensor values (temperature, humidity, voltage, etc.) recorded by the Monitoring System 50 are transmitted to Cacti via SNMP (Simple Network Management Protocol).
In simple terms, the measurement data transmitted via LAN/WAN is stored in a database and can be easily visualized graphically using Cacti Tool. Cacti supports exporting the visualized measurement data as .png or .gif images.
Alternatively, the temperature sensors connected to the Monitoring System 50 can also be integrated into SNMP-compatible SCADA, building management, and network management software. Examples of such monitoring solutions include HP OpenView, Nagios, check_MK, Icinga 2, OpenNMS, PRTG, WhatsUp Gold, and Zabbix.
The SNMP-compatible monitoring system 100 can be equipped with a magnetic contact sensor and an alarm siren with a strobe light function. The magnetic contact sensor is easily mounted between the door and the door frame. The siren is connected to one of the two 12V outputs. You can then configure the magnetic contact sensor in the logic diagram of your Ethernet-based monitoring system.
Time and trigger functions are available for this purpose. The monitoring system 100 can send SNMP traps to PRTG and also activate the alarm siren. Because the magnetic contact sensor is equipped with an OID, PRTG can directly query the current door status (open/closed).
If you only want to send SMS alarm messages with your monitoring system, the internal GSM modem is sufficient.
Didactum's engineers deliberately chose not to use fans in the development of their IP-based monitoring systems. The reason is that a fan failure could compromise the cooling of the business-critical monitoring system.
Didactum's Ethernet-based monitoring devices are approved for operation in environments ranging from -10°C to +85°C (as of November 2018). The relative humidity must be between 5% and a maximum of 95% relative humidity (non-condensing).
Each measuring and monitoring device is equipped with an onboard temperature sensor. If the permissible operating temperature is exceeded or falls below the set temperature, you can receive timely notifications from the networked monitoring device via SNMP trap, SMS (via LTE or GSM modem), or email. An audiovisual alarm for critical temperatures is also supported (an optional alarm siren is required).
Didactum's engineering and support are based in Germany, specifically in Münster (North Rhine-Westphalia). Contract manufacturing is handled by specialized companies located within the EU. Firmware installation and subsequent functional testing of the networked measurement and monitoring systems are also performed in Germany.
Every IP-based measuring and monitoring device from Didactum is equipped with an integrated web server. The German-language web interface can be accessed via the web browser of a smartphone, tablet, PC, or laptop. You can also display the measured values of all connected sensors graphically in the web interface.
Since each monitoring device supports the SNMP protocols v1, v2c, and v3 (encrypted), the measured values can also be queried via SNMP (Simple Network Management Protocol). The measured values can also be transmitted from the network-based monitoring devices via Syslog, RSS feed, CSV, or XML file.
The 100 (DC) / 400 / 500 (DC) / 600 (DC) / 700 (DC) series monitoring systems can be mounted in a 19-inch wall, network, or server cabinet using a 19-inch rackmount kit. These mounting brackets are included with the 500 / 600 / 700 series systems. The rackmount kit for cabinet mounting of the 100 and 400 series monitoring systems is available separately.
The 500 series monitoring systems are supplied with an internal 230V power supply including a power cord. The 50, 100, and 300 series monitoring systems include an external power supply.
Didactum's current Ethernet-based measurement and monitoring systems also support Modbus RTU. The Modbus RTU module or Modbus USB/RS485 adapter is required for this (available separately in the online shop).
Measure and record important consumption data from single-phase and three-phase meters with the SNMP-compatible monitoring systems. Suitable gas, oil, water, or heat meters can also be remotely monitored via a TCP/IP network.
There is no universally applicable formula for the maximum permissible temperature and humidity in a computer and server room. The vast majority of server, network, and storage hardware manufacturers specify a maximum permissible ambient temperature of 27 degrees Celsius. The humidity in the server room should be between 50% and a maximum of 55%. Sustained critical temperature and humidity levels in the server room can drastically reduce the lifespan of the hardware.
The page you are viewing in the web interface of your IT monitoring system is automatically updated every 30 seconds. This eliminates the need to manually reload the page in your web browser. You will see a notification in the bottom left corner of your browser window, such as "Last updated 11:50:47 / Next updated 11:51:17".
Several energy suppliers in the Alpine region have been successfully using Didactum monitoring systems in hydroelectric power plants for many years. The maximum operating altitude approved by the developers of the Didactum monitoring systems is 2,800 meters.
In the web interface of the Ethernet-based measuring and monitoring device, up to 15 different mobile phone numbers can be entered in the "SMS Messages" field. If SMS alarm messages need to be sent to more than 15 different phone numbers, please create a second alarm rule under "Logical Scheme".
Should problems occur with sending SMS alerts, they will be logged in the Didactum system. First, restart the monitoring unit (Web interface => "System Menu" => "Restart the system" and click "OK"). Alternatively, please remove the SIM card from the internal GSM/LTE modem and test it with your mobile phone/smartphone.
Failed SMS sending can have the following causes:
- Technical defect of the SIM card
- SIM card blocked (incorrect SIM PIN entry or blocking by the mobile network provider)
- Negative balance on the SIM card account
- Low signal level
- Incorrect entry format of the registered phone number (correct format +49172xxxxxxx)
- Entry of an incorrect/invalid phone number
In our online shop for IT security technology, you'll find a wide range of starter kits for monitoring critical infrastructures under "Bundle Offers." If you have any questions or require expert advice, please feel free to contact our sales team.
Didactum's LAN-based measurement and alarm systems are equipped with capacitors, so that in the event of a power outage, alarm messages can theoretically still be sent via the integrated GSM or LTE modem.
In practice, however, this approach carries some risks. Generally, the use of an uninterruptible power supply (UPS) is recommended as protection against power outages. Standby or offline UPS systems from leading manufacturers are available for well under €100. Simply search for "desktop UPS" online.
Didactum's Ethernet-based monitoring and alarm systems support the SNMP standards v1, v2c, and the encrypted v3 protocol (Simple Network Management Protocol). To monitor the measurement data (temperature, humidity, air circulation, energy consumption, etc.) of the connected sensors and alarm contacts (heating, emergency diesel generator, air conditioning) with your CAFM or building management solution, an SNMP interface is required. Simply contact your CAFM facility management software provider for this. If your software is equipped with such an SNMP interface, you can easily import the SNMP MIB file from Didactum. Alternatively, please use an MIB browser to determine the OID (Object Identifier) of the respective sensor.
Every Didactum IT monitoring system is equipped with I/O contacts. Connect the system to the emergency shutdown switch of your UPS system using a two-wire cable. If the smoke detector detects a fire or other hazard, the Didactum monitoring system can automatically cut power to the UPS system via a relay circuit. This rule can be easily configured in the built-in logic. Of course, the I/O contacts can also be switched manually via the user-friendly web interface.
Connecting contactors and emergency stop buttons is supported. Define the normal state (normally open/normally closed) of the button in the web interface. Then, configure the desired actions (relay switching, siren, etc.) and alarm notifications (SNMP, email, SMS) in the web interface.
The Didactum Monitoring System 300 is a fully SNMP-compatible remote control system with a small distribution box for mounting on a DIN rail.
The automation and remote control devices of the 100 / 300 / 400 / 500 / 600 / 700 series can be equipped with the high-performance, internal LTE modem. MIMO (Multiple-Input-Multiple-Output) transmission is supported by the LTE modem (at an additional cost).
The Didactum Monitoring System 500 DC (direct current) offers two voltage inputs upon request. A MOSFET redundancy module for the Monitoring System 300 (DIN rail) is available in the online shop upon request.
Please note that due to the hardware design of the 500 II IT monitoring system, the expansion board (bistable relays / additional potential-free dry contacts / connection for 12V backup power supply) and the RS485 / Modbus RTU module cannot be installed simultaneously. The principle here is "either/or".
No. When the 1-Wire module is installed, the expansion board of the Monitoring System 500 II is no longer needed.
Please note that connecting a USB hub is not officially supported. If you require a USB surveillance camera and flash storage for sensor data, video recordings, and log files simultaneously, please use the Didactum Monitoring Systems model series 400 / 500 (DC) / 600 / 700. These devices feature an internal SD card slot. A USB hub can be connected to Didactum web thermometers, Rack Monitoring Systems (RMS), and PDUs. However, please be aware that inexpensive, no-name USB hubs may cause problems.
Didactum hardware developers have successfully tested the "TRANCEND TS-RDP7K (Multireader + Hub)" model with the networked Monitoring System 100 IV. The USB camera and flash drive function simultaneously on this USB hub. However, please do not use multiple flash drives with this USB hub, as it only supports one drive at a time. As mentioned previously, USB hubs are not officially supported. Please refrain from submitting support requests.
