To reset your smart Didactum Monitoring System to factory settings, you can

  • Go to the web interface => "System menu" => "Reset settings to default values" => select "complete”
  • "refuel" your remote infrastructure control via the CPU tool

Important note from the editors: Please note that by resetting to the delivery status, all settings and measurement data are permanently deleted!

As described in detail in the printed quick guide of the smart monitoring unit, the configuration you have made is only saved permanently by clicking on the disk symbol (top right in the web interface). If you have previously saved the configuration of your monitoring unit , you can easily import the backup file. To do so, go to "System menu" = "Firmware" => "Upload Source" and select your file called "Settings.zor" (without quotation marks). After the restart, your smart monitoring system is restored.

No. The dashboard is always empty when the smart monitoring system is first set up. How to set up your individual dashboard is shown here.

The connection of contactors and emergency stop buttons is supported. Define the normal state (normally open / normally closed) of the button in the web interface of your alarm system. Then you define the desired actions (relay switching, siren etc.) and alarm messages (SNMP, e-mail, SMS) in the web interface.

Every Didactum Monitoring System is equipped with I / O contacts. Connect the remote monitor to the emergency shutdown of your UPS system using a two-wire cable. If the smoke detector detects a fire, the monitoring unit can automatically switch off the UPS system via a relay circuit. The rule can be easily mapped in the built-in logic. Of course, the I / O contacts can also be switched manually in the easy-to-use multilingual web interface.

Please go to the entry "System menu" in the WebGUI (bottom left). In the "Export" tab, click on "Save log to disk" to export the syslog of your remote monitoring unit. Then go to "Download current settings" and click on “OK”. In the new window "Select settings" please leave all check marks set and then click on "OK". Please send the two files named "Syslog.txt" and "settings.zor" to the support staff by e-mail. If you have received a ticket number, please always state it in the subject line of your e-mail. This will speed up the processing of your support request.

This error message states that the metering & monitoring unit can not reach the address ''. Either the DNS is not configured or a firewall is blocking the communication. You can use the remote monitor's built-in ping feature to check if the remote host computer is available.

The Ethernet-based remote monitoring units of the model series 50 / 100 IV (DC) / 400 /500 II (DC) permit an physical operating environment from -10 ° C to max. + 85 ° C (14° F to 185° F) at 5% to max. 95% relative humidity (non-condensing). Each Didactum remote monitoring system is equipped with an onboard temp sensor for temperature measurement and monitoring inside the metal case. If the maximum permissible operating temperature is exceeded, you can be notified via SNMP trap, e-mail and / or SMS (via GSM / LTE modem or e-mail SMS gateway). Optionally, the alarm siren including LED flash lights can be connected to the main monitoring unit to report the critical operating temperature.

Please check the fuse of your 500 II monitor. This is located right next to the power connector on the back. How to replace a defective fuse is described here.

To display the measurement diagrams in the webGUI, simply click on the "+" sign in the upper left corner. A new window will appear with the sensors connected to your networked remote monitoring unit. Then select the desired environmental sensors and then click on "ok". The measured data will then be displayed graphically immediately. The screenshot below gives you more information.
