Question:

We use the Monitoring System 50 to measure important environmental conditions in our server room. In case of a failure of our air conditioning, we would like to receive SMS alerts directly to our mobile phones. How does this work without using a GPRS / GSM hardware modem?

Answer:

By using a so-called E-Mail to SMS gateway, the e-mail alerts of your remote monitoring device can be sent directly to your mobile phone via SMS. This paid service is offered by serveral cell phone providers. An e-mail to SMS Gateway is set up within minutes. Just contact the hotline of your wireless carrier.


Question:

We have procured the IP-based Monitoring System 100 III including GSM modem. Unfortunately our new SIM card is not recognized. What can be the cause?

Answer:

Our egineers regularly test the GSM modems of our remote monitoring systems with SIM cards from leading cell phone providers. Updated network operator settings are provided in the form of firmware updates. Please insert your SIM card into a mobile phone / smartphone. Check if your SIM card has already been activated. Often, the SIM card must be manually activated by the user. Then deactivate the pin code of SIM card with your mobile phone and plug it back into the internal GSM modem of your remote monitoring system. The SMS notification should now work properly.


Question:

We have installed the IP-driven 500 II system for safety and environmental monitoring in our 19 inch server cabinet. The settings in the "GSM Modem" menu have been set up correctly. We also deactivated the PIN query. Under "Current status" we always receive the message "Alarm". The signal strength of the GSM modem is displayed with 0%. How can this problem be solved?

Answer:

Please use a SIM card from a different mobile carrier. Our many years of experience have shown, that the various mobile carriers offer different mobile network coverage. Furthermore, the installation of a weatherproof outdoor antenna is recommended in server room and data center infrastructure. 


Question:

I have problems with my SIM card and the GSM modem. How can I find the cause?

Answer:

Please go into the settings of your GSM modem and change to "Debug" under "Verbosity Level". The IP-based monitoring system then will save the messages in a LOG file. This looks like this:

Network registration

First:

0 – No registration code

1 – Yes have registration code

2 – Yes have registration code  + additional

Second:

0 – No registration, no search

1 – have registration, home network

2 – No registration, no search

3 – registration denied

4 – unknown 

5 – roaming

 

The messages in the LOG file will help you to identify the problems of your SIM card.


Question:

We use two environmental monitoring systems for temperature monitoring of our two spatially separated server rooms. We would now like to be alerted by SMS. Does each monitoring unit have to be equipped with a GSM modem?

Answer:

The new generation of IT monitoring systems (Didactum Monitoring System 50 / 100II / 100III (DC) / 400 / 500 II (DC) / 600 / 700 ) offers an integrated "SMS Gate" function. This means that only one Didactum IT monitoring system has to be equipped with a GSM modem. Then the others remote monitoring devices can use the "SMS Gate" for sending SMS notifications and alerts.


Question:

How is the SIM card inserted in the internal GPRS / GSM modem of the environmental monitoring device?

Answer:

First, check if your monitor device is equipped with a GSM modem. The internal GSM modem can be found in the web interface under "System tree".  If your IT monitoring device does not have the GSM option, please order it in our online store. Carefully insert the mini SIM card with the chip facing down into the SIM card slot of the internal GSM modem, i.e. the notch of the mini-SIM card is on the left side. If you have a micro or nano SIM card, please use a suitable SIM card adapter or remove only the mini SIM card from the (SIM) card carrier.


Question:

We have bought the Didactum Monitoring System 100 III including GSM modem. Unfortunately, our new SIM card is not recognized. What can be the reason?

Answer:

We regularly test the GSM modems of our remote monitoring unit with SIM cards from leading mobile service providers. Any updated network operator settings will be provided by us in the form of firmware updates. Please insert the SIM card into a mobile phone / smartphone. Check if the mobile card has already been activated. Often the SIM card itself must be activated / unlocked by the user. Then deactivate with your mobile phone the PIN CODE query of the SIM card and plug it back into the GSM modem of the monitoring system. The SMS notifications should then work properly.
