After connecting the Device, close the lock on the connection to ensure it is water
resistant and firmly secured.
When powered on, the Device produces a single green flash to indicate that power
is supplied. After that, the Gateway will produce a series of four flashes every five
seconds (see details in chapter VI). A new Device usually flashes GREEN-GREEN-
RED-GREEN after the installation, meaning that it is connected properly.
You can also check the NMEA 2000 connection and firmware version from a chart
plotter. Please, see chapter IX for details.
