Maretron’s Direct Current Monitor (DCM100) provides information about the DC electrical system. In this example the DCM100 is used to monitor the house battery bank. This comprehensive system includes an 8” touchscreen (TSM800C) for displaying information about the battery as well as triggering any associated alarms or warnings. Triggered alarms or warnings can be sent off of the vessel using the texting module (SMS100), for example if the battery voltage drops too low for the bilge pumps to work. The Internet Protocol Gateway (IPG100) and WiFi router (E2500) allows the information to be viewed wirelessly on the boat using smartphones and tablets and remotely from the shore with an Internet connection.
The following table shows the products included within this example system plus a list of the information or data available for display.
| Product | Description | Available Data List |
| DCM100 | Battery monitor | Monitors voltage, current, state of charge and battery temperature |
| TSM800C | Helm display | Displays data in this list |
| IPG100 | N2K to ethernet | NMEA 2000 to ethernet gateway |
| E2500 | Wifi router | Allows monitoring wirelessly or wired onboard, or remotely with internet connection |
| SMS100 | Texting module | Sends text messages to one or more phone numbers when any monitored data in this list goes outside programmed limits |
| MCS-25G | Real Time Cloud Service | Subscription service that allows real time access to the vessel from anywhere in the world with internet connection |
