To identify the ideal Industrial Cellular Modem for your application we have developed the Modem Selector Tool which is a configurable filter to narrow down the results to match your exact requirements.

Siretta Modem Range

The Siretta industrial modem solutions are a family of cellular enabled modems which have been designed to an industrial specification to allow an easy connection for remote devices over the internet. The family of products supports a standard set of features including a wide range and robust power supply, RS232 and USB serial connectivity and extended temperature spec as standard.

Each member of the family supports an embedded TCP/IP stack for simple network connectivity and an enhanced set of AT commands to support many advanced features such as FTP, email, SMS, CSD, direct socket connections and over the air software updates. As a result the units are designed to be used as a direct replacement for existing equipment and can be easily setup with the correct commands to operate out-of-the-box.

The industrial modem family can be configured to detect the cellular network provider, signal strength and can perform a complete network survey to establish the optimum network for the location.

Siretta Industrial Modem Application Example

The power supply has been designed to cope with difficult operating environments such as wide voltage spikes seen with an engine cranking and also extremes of operation at low and high voltage operation. With the latest application developments there is a requirement for solutions to run on a much lower power budget and as a result Siretta has designed a family of extremely low power products. These products encompass an intelligent power management solution to shut down power to any non essential components and reduce consumption to an absolute minimum. When running the cellular engine in its lowest power state these devices can operate at less than 1mA whilst remaining connected to the cellular network. This means that they are always online and available to respond to incoming socket connections whilst drawing substantially lower power than existing solutions.

The Siretta industrial modem family also support eSIM profiles to allow multiple SIM profiles to be stored within the cellular engine. This allows users to specify in real time which network they want to connect to and enables a global connectivity platform to take advantage of different pricing structures around the globe. Profiles can also be downloaded in to the unit once they have been shipped in to the field which means that there is no longer a need for an engineering visit.

The Siretta industrial modem solutions can be connected to most existing applications and remote equipment in the field can be configured to control and remotely access online resources with the minimal amount of effort using the serial interface and a standard set of AT commands.

The industrial managed solutions are intelligent modems which have been designed to connect remote RS232 serial equipment over a TCP/IP connection to a central location. Very little knowledge is required to setup the modem and configure the linkCONNECT software. The unit is setup to operate out-of-the-box and configured remotely via SMS once in the field or alternatively pre configured before deployment via a serial configuration tool.

The configuration of the managed modem solutions is controlled by the user simply using standard SMS messages sent from a standard mobile phone. Alternatively when configuring large volumes of units there is a configuration tool which configures the unit over RS232 serial and can be replicated very quickly to aid the production programming.

The managed modems deal with all common cellular network issues and maintain a robust connection to the cellular network enabling a consistent communication channel with your remote equipment. The units are configurable as a dial-up client using static or dynamic IP SIMs or as a dial-in server using a static IP SIM card. This offers the most flexibility to gain access to information on your remote equipment and provides the most cost effective solution with regards to providing a cellular tariff for your entire estate.

Siretta industrial managed solutions are used to cellular enable new and existing equipment without any need for product development or the need to understand complicated software application development. The managed modems work out of the box and can be installed immediately in to you application.

The managed solutions can be setup simply via a standard mobile phone and uses a remote link to transmit information from your application to a central location to record, log and control the application. The Siretta managed solution enables remote access to all of the interfaces in your application and can query a host of sensors, processes, power usage and any number of other important parameters.

The managed modem detects the GSM network provider and automatically configures the GPRS network settings for the connected network eliminating the need to enter any network specific details. The only settings which are required are the IP address of the server where the solution is connecting to and the listening port on the server. Once these settings are configured the unit will establish and maintain a connection to the server permanently, in the event of the network dropping a connection the unit will attempt to reconnect and employs a number of techniques to ensure a robust, reliable connection.

The managed modem solution is agnostic of the connected equipment as the software within the unit controls and manages the internet link and TCP connection to route the RS232 serial data over the cellular network. The unit supports any protocol or data type including binary and ASCII so that the underlying operating system or control software within the equipment does not need to understand the connection mechanics which makes connecting any equipment easy and simple.
