WL-2 GSM Pod


Technical Features

The WL-2 GSM Pod is a highly integrated module that includes the Nokia 12 GSM/GPRS engine and all the supporting circuitry such as switched mode power supply, SIM card connector, serial interfaces, industrial strength I/O and interface connectors for external boards such as GPS, audio and connection to AT command based devices. All these features are packed into a small form factor, approximately 65 x 85mm board. The Pod is designed for ease of mounting to suit many applications ranging from DIN rail enclosures to flat panel mounting and board to board connection.
The Pod can be programmed easily over a standard serial cable using the Configurator software. With this Windows based program, you can set the WL-2 to various operating modes such as AT command and User Control modes. You can also set up the Pod for other M2M applications such as the Nokia M2M platform or even direct data communications to your own Company servers and the Internet.

By using the User Control mode in the Configurator software, you can be up and running very fast with standard I/O applications for remote sensing and control over the GSM network. You can easily program the Pod with the alarm and control messages that need to be sent and received using SMS text messages and your mobile phone. A prepaid SIM card is sufficient for most applications.

Key Features

  • Small highly integrated GSM/GPRS Pod (65x85mm)
  • Ready-to-Go for simple SMS controlled I/O applications
  • Direct interfacing to industrial equipment using robust I/O interfaces
  • External interfaces for optional GPS, Serial, Audio and AT controlled devices
  • Uses Nokia 12 GSM engine which supports GSM/GPRS communications
  • Java with remote IMlet downloading for further application development
  • Easy setup of I/O and M2M parameters with Windows Configurator software
  • Available in a DIN rail enclosure or on a pre-drilled plastic base plate
