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.
