The smart measurement and alarm systems of Didactum were developed in such a way that no maintenance or care on the hardware must be carried out. Inside the housing there are no components that should be maintained or replaced by the customer himself. If the monitoring hardware is equipped with ventilation openings, please ensure that these are not covered. A possible dust accumulation should be carefully removed with a dry antistatic cloth.

Simply insert an empty USB stick into the Didactum monitoring device and please wait about 60 seconds. The device automatically creates a file called "". Just open this file with an editor and you will see the currently assigned IP address, host name, netmask, gateway, DNS etc. of the your remote monitoring unit.

The networked monitoring and fault alarm systems from manufacturer Didactum support the SNMP protocols v1, v2c and v3 (encrypted). In order to monitor the measurement data (temperature / humidity / energy consumption, etc.) of the connected IP sensors and dry contacts (heating, emergency diesel, air conditioning) with your CAFM or building management solution, a so-called SNMP interface is required. To do this, simply contact the provider of your CAFM facility management software. If your software is equipped with such an SNMP interface, you can easily import the SNMP MIB file from Didactum. Alternatively, please use a MIB browser to identify the OID (Object Identifier) of the  respective sensor.

Didactum's LAN-based remote monitoring and alarm systems are equipped with capacitors, so that in the event of a power failure, alerts can still be sent theoretically via the integrated GSM or LTE modem. In practice, such an approach has risks. Basically, the use of an uninterruptible power supply (UPS) is recommended as protection against a power failure. Low cost standby or offline UPS systems are available from leading manufacturers.

In the online shop for IT infrastructure monitoring solutions you find under Bundle a variety of starter sets. If you have questions or need a consultation, just contact our sales team.

Possible problems with SMS notification are stored in the log of your remote rack monitoring device. First, restart the unit (Web interface => "System Menu" => "Reboot the system" and click on "OK".) Alternatively, please remove the SIM card from the internal GSM / LTE modem and test it with your mobile phone / smartphone.

A faulty SMS dispatch can have the following causes:

  • Technical defect of the SIM card
  • SIM card is blocked (incorrect entry SIM PIN or blocking by the mobile service provider)
  • Negative balance on the account of the SIM card
  • Low signal level
  • Incorrect format of the telephone number
  •  Entering a wrong / invalid phone number

In the web interface of the IP based monitoring unit, up to 15 different mobile telephone numbers can be stored in the "SMS Messages" entry. If SMS notifications have to be sent to more than 15 different phone numbers, please create a second alarm rule under the field "Logic schemes".

The carriage of lithium batteries has been identified as an emerging risk to airline operations. Therefore your web-enabled main monitoring unit is shipped by air freight without the 3V CR2032 lithium cell. Please buy this cheap battery cell on-site in your country. You find additional information here.

In simple words, the Didactum Monitoring System 100 III offers more functions. This monitoring device provides more connections for Didactum's intelligent IP capable sensors. The CAN expansion port (Controller Area Network) of 100 III monitoring device enables flexible expansion with additional sensor boxes or Dry Contact units. In addition a GPRS / GSM modem and a 19-inch Rack Mount Kit are also available for this monitoring device (at extra cost).

The infrastructure remote monitoring devices 500 II and 500 II DC (48V DC power supply) are supplied as standard including the extension board (Part No. 14120). As an option, the internal GSM modem (Part No. 14108) is available. Alternatively, you can also order the internal 1-Wire module (Part No. 14110). Please note that when ordering the 500 II (DC) Monitoring System including 1-Wire module, it is not possible to install the extension board (Part No. 14120). However, the 500 II (DC) monitoring device incl. 1-Wire module can be equipped with the GSM modem.

Here again in short form:

  • 500 II (DC) including extension board and GSM modem = possible
  • 500 II (DC) including extension board and 1 wire board = not possible
  • 500 II (DC) exclusive expansion board including 1 wire board and GSM modem = possible

Most of our network enabled sensors are supplied with a 2 meter long RJ11/RJ12 connection cable as well as mounting material (mounting kit / screws). The sensors are connected to the IP-based monitoring system via Plug `n` Play and automatically identified.

If you want to install the Didactum analogue sensors farther away from the Didactum control unit, you can order suitable RJ11 / RJ12 extension cables as well as sensor cables in our online store. Important: Please note that the Didactum DC sensors are wired exclusively via 6-core 6P6C patch cable.

Put simply, the grounding / earthing terminal is used for the functional grounding of the networked remote measuring and monitoring devices in the context of electromagnetic compatibility (EMC).

In the scope of delivery of Monitoring System 100 III you find 1* monitoring device 100 III, 1* 100-240V 0.35A power supply, 1* sensor temperature, 1*10/100 CAT5E Ethernet patch cable, 1* USB 2.0 adapter cable MINI B-A W/F, 1*set of self-adhesive rubber feet, 1* connector for 4 dry contact inputs, 1* connector for 12VDC outputs, 1* EC certificate, 1* guarantee registration card, 1* English language quick start guide. For models with internal GSM modem 1* angle antenna is included. (State 07/2017).

All SNMP compatible Didactum monitoring systems are equipped with an internal temperature sensor. This temperature sensor is used for measuring and monitoring the temperature inside the housing. In the integrated logic of your Didactum monitoring system, you can set individual limits and the desired alert for this sensor.
