III. LED Signals
1.
Signal with period of 5 seconds, two flashes of the LED.
The first flash indicates the condition
of the CAN1 interface network. Green LED flash indicates that data has been received or successfully
sent on CAN1 interface within the last 5 seconds period, red if not. The second flash indicates
the condition of the CAN2 interface network.
The Device can be configured to receive only a limited set of NMEA 2000 messages
(see SectionVII.3), the remaining messages are filtered at the hardware level. In this regard,
some NMEA 2000 networks can indicate a red light much of the time, even when
the network is functioning normally. In this case, to check the connection, turn one device that
is on the network (e.g. the chart plotter) off and on again. The status of the network will be displayed
with green flashes for some time as the device is powering up and connecting.
2.
Three flashes (colors may vary), one time after inserting the MicroSD card into
the Device.
See Section V.

Diagnostics mode started / finished, see Section X.
4.
Five green flashes when NMEA 2000 network is turned on.
The Device has the MicroSD
