SMS100 - Short Message Service (Text) Module Maretron''s SMS100 is a mobile or cellular modem that automatically sends text message alerts from your vessel to your phone. The SMS100 works together with Maretron''sr dedicated displays (DSM150/DSM250) or N2KViewr software (with the optional N2KView-Alerts module) to detect programmable alert conditions from sensors interconnected on an NMEA 2000r network. The displays or N2KViewr software instruct the SMS100 to connect to the cellular network and transmit an alert message to selected telephone numbers. Whether it is high bilge water low battery voltage unplugged shore power or an opened hatch or door the SMS100 quickly alerts you to conditions onboard your vessel that require attention anywhere you have cellular network coverage.
