P/N: DSM150-02
3.5" High Bright Color Display
NMEA 2000

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.

nmea-2000-logo-productsUnlike 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
  • 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:
