Depending on the version, an analog or GSM modem is integrated in the housing of the SSW7-TS. The analog modem can be configured for use worldwide. All connecting cables required for operation are included. For mobile use, or if there is no telephone line, the SSW7-TS with GSM modem (quad band) is the right choice.
Using the serial interface, the SSW7-TS with modem can also be used as a PC adapter for on-site use. The respective modem can also be used for remote maintenance of a VISU/SCADA application without the TS adapter function. 
The SSW7-TS with modem is powered by the CPU via the MPI cable or external voltage connection. 
The SSW7-TS with modem can be provided with new firmware over a modem connection using the free software SHTools. This means a functional expansion of an adapter already installed in the system is possible. The latest SHTools version is available for download at no charge at our website www.helmholz.com.
