  • GPRS / GSM data transfer

Characteristics of GPRS Adapter:

  • Transfer of alarm control panel’s Contact-ID signals through GPRS channel
  • Redundancy modes: 
    1. GSM switched line
    2. PSTN phone line
  • Continuous testing of connection existence even at every 3 minutes
  • Significantly increased signal density and numerous terminal equipments (4000 pieces / TEX MVP server)
  • Signals are forwarded as an IP package to the TEX-MVP or TELLMon server. The data communication of the server corresponds to switched line receiver’s communication, by this means it is ready to be inserted into an existing monitoring system
  • Independent contact input with definable Contact-ID code assignment (e.g. sabotage notification)
  • GSM failure output
  • Supervision of the PSTN phone line
  • Possibility of event filtering in GSM mode

  1. 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.

  2. It is not possible to read or upload the setting to the device with the programming software. The connection does not get through, or sometimes the downloading stops.

    Please power up the module first, after that connect it to the computer.

  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.
