3. Installation Before starting installation select a suitable location for the MOBAlert switch plate and MOBAlert NMEA 2000 Interface. The switch plate should be installed on deck, in a location where the helmsman or crew can quickly and easily access and operate it, but where it cannot be inadvertently leaned or pushed against causing a false alarm to be generated.

The MOBAlert, has an integral NMEA2000 cable terminated with a male connector, to connect to a standard NMEA2000 network via a spare “T-Piece”. If you are creating a new NMEA2000 network, you may wish to Digital Yacht’s NMEA2000 Starter Kit, that provides all of the cables, connectors and terminators consider required for a basic NMEA2000 network.
Once the MOBAlert has been installed, it will automatically operate with no additional interaction. At power up, all of the LEDs will flash briefly on the MOBAlert NMEA 2000 Interface. Once the MOBAlert has initialised and claimed an NMEA 2000 address, the N2K LED will continuously flash/flicker depending on the amount of data being received.
