Maretron's DSM150 is a high-resolution sunlight viewable color display that interprets and displays NMEA 2000® instrument, navigation, and vessel monitoring data. The DSM150 is a user friendly dedicated marine display with custom screen configurations and an easy-to-use five-key illuminated keypad. In addition to the monitoring and display capabilities, the DSM150 features an alert / alarm package and electrical switching capability.

Unlike traditional single-display units, DSM150 users can choose numeric, gauge, bar or graph formats in single or multiple displays, with cycling options possible for a wide range of favorite data. These multiple display options conserve mounting space and reduce overall system cost.

The DSM150 will directly connect with any NMEA 2000® network and with the exception of AIS data will display any or all information captured throughout the vessel. Various audio and visual alarms are also programmable. The DSM150 displays a multitude of information including AC power, anchor status, battery, depth, electrical distribution, engine, environment, fuel management, GPS, heading, navigation, pressure/vacuum, rudder, speed, status indicators, tanks, temperature, time, transmission, water makers, weather, wind and more.


The DSM150 includes a comprehensive, flexible alert capability. Configure audio and visual alerts on virtually any data that the DSM150 is capable of monitoring. Available alert types include:

  • High alert
  • Low alert
  • Inside radius alert
  • Data unavailable alert
  • On alert
  • Off alert
  • Circuit breaker tripped alert
  • Course alert
  • GPS quality alert
  • Outside radius alert
  • Inside radius alert
  • Direction alert
  • Timer alert

The DSM150 is capable of sharing alert information with other DSM150 units as well as any DSM250 and N2KView® installations on the network. An alert defined on any device can be acknowledged on any other device on the network. Following is a screenshot of a shallow water alert:

Once the alert appears, you simply press the "Enter" key twice to see the Alert Status screen, shown here:
