IV. Device Connection and Testing
The Device requires no maintenance. When deciding where to install the Device, choose a dry mounting
location. Avoid places where the Device can be flooded with water, this can damage it. The Device sensor
can be mounted inside or outside, see the sensor mounting recommendations in the previous chapter.
The Device is directly connected to the bus without a drop cable. Before connecting the Device, turn off
the bus power supply. Refer to the manufacturer's documentation if you have any questions regarding
the use of connecting cables, terminators and connectors:
•
SeaTalk NG Reference Manual (81300-1) for Raymarine networks
•
Technical Reference for Garmin NMEA 2000 Products (190-00891-00) for Garmin networks
After connecting the Device, close the lock on the connection to ensure water resistance and reliability.
After turning on the bus power supply, the LED of the Device with factory settings will produce
two short signals every second. This indicates normal operation (see chapter VIII).
If the Device is connected to a network having a chart plotter or any other device transmitting
“Datum” (PGN 129044) or “Magnetic Variation” (PGN 127258) messages, the Device will produce
six half-second LED signals when a message of that type is received for the first time after power
is turned on. This usually happens within 15 seconds after the Device is turned on. The signal series
confirms that the Device is properly connected to the NMEA 2000 network and that the chart plotter
is able to receive data from the Device.
The Device information should be displayed in the list of NMEA 2000 devices (SeaTalk NG, SimNet,
Furuno CAN) or in the common list of external devices on the chart plotter (see Figure 1 on the next page).
Usually, access to this list is in the "Diagnostics", "External Interfaces" or "External devices" menu.
Data from the Device are available to all the equipment connected to the network and can be displayed
simultaneously on several chart plotters and digital navigation instruments.
