  1. The device does not activate the relay output on an incoming call. Why?

    The caller ID identification must be enabled on the inserted SIM by the GSM service provider. Without this, the device will be unable to identify the incoming call ID identification. Insert the SIM card (which is in the device) into a mobile phone; call the customer service of the GSM service and enable this service in the menu. Make sure you set the timing of the relay output (if the timing is 0, the relay will not activate).

  2. The device is not connecting to the GPRS net. Why?

    Check the APN settings, the power supply and power requirements of the module, as well as the GSM antenna connection and signal strength.

  3. After installing the programmer software there is an error message saying that the DLL file is missing and it can not start.

    Some operating systems create a missing DLL file after connecting to the module. Connect the module through a USB to the computer, and after this start the programming software again.

  4. The module sends a long line of continuous letter / sequence SMS message to the SMS forwarding featured phone number. What is the reason for this?

    This phenomenon happens when you do not receive a regular SMS (text) to the phone module, but some kind of a multimedia message (MMS photo) or some other encoded message (for example, encoded Cyrillic letters with accents or other capitalization). An industrial phone module is not able to handle this, that's why the mentioned letters/sequences are converted into Unicode form and are forwarded to your phone (depending on the size of the message 1 MMS can be received in 3 or 4 SMSs). Please note that in this case there is no problem with the device itself, but this phenomenon is caused by the above-described reason. If this occurs regularly, there is a good chance that it is an advertising / marketing message sent by the service provider, which can only be stopped by either asking the service-provider not to send such messages to this given phone number or by turning off the message forwarding function (in the settings: delete the SMS forwarding phone number), if this function is not absolutely necessary.
