1 Description
1.1 Summary
The GSM-PRO2(E) is a compact remote control and messaging system. All IOs are monitored by SMS and email
and controlled by SMS communication through the GSM network.
The module can be configured with the GSM-PRO2 PC-software. Each IO can be modified by user-defined
parameter names and messages. A selected group of users can be chosen from the phonebook to control the
module, or only receive messages.
On each defined input status change (rising or falling flank for digital inputs or reached level for analog inputs)
the module sends a pre- or user-defined message to the selected group of users.
The outputs can be set when a selected user sends a pre- or user-defined SMS to the GSM-PRO2(E).
The GSM-PRO2(E) sends a periodical message on user defined times. On power loss the module holds enough
power to send SMS messages to a selected group of users. It also sends messages when coming back from a
power reset.
1.2 Module types
The GSM-PRO2 consists of the modules as described below. For images and connection examples in his
document the outline of the GSM-PRO2 is used.
