Maretron's DSM250 is a high-resolution sunlight viewable color display that allows easy interpretation of NMEA 2000^® instrument and navigation data through custom display configurations, featuring an easy-to-use five-key illuminated keypad.

Unlike traditional single-display units, DSM250 users can choose numeric, gauge, 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 DSM250 will directly connect with any NMEA 2000^® network and display any or all information captured throughout the vessel. Various audio and visual alarms are also programmable.

The DSM250 displays a multitude of information including AC power, battery, depth, engine, environment, fuel management, GPS, heading, navigation, rudder, speed, tanks, time, transmission, weather, wind and more.

The DSM250 now includes a comprehensive, flexible alert capability. Configure audio and visual alerts on virtually any data that the DSM250 is capable of monitoring. Available alert types include:

• High alert
• Low 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 DSM250 is capable of sharing alert information with other DSM250 units as well as any DSM410 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:
