Accessory wake up
The yellow colored accessory wake up line may be used to
control the power state of Navico modules such as SonicHub,
StructureScan, and Broadband radar. This means that the modules
are turned on the moment the display is powered up. For
connection, simply combine all yellow wires on a common bus or to
a single termination point.
Note:
Broadband radar will be started in ‘standby’ mode, never
‘transmit’ mode, when triggered by the accessory wake up line.
The following demonstrates the power connections for a typical
small system.
