•
If the bus-master is out of order , one of the other units that is able to be a bus-
master, should become a new Network Manager (according to a special
procedure).
•
If a new unit is added, the bus-master shall take care and the unit will be taken
into the ”community” and given its own ID/identity.
The NX2 Server will NOT ask every instrument if they have something to say,
only if they stop answering to ”next-sender” packet.
Possible communication errors.
Error 03 is a local error message shown on instruments with LCD display when
the instrument is unable to read Nexus data during approximate 10 sec. then it
will display Err03.
Example on Err03: Lose wire, or the white and yellow wire are mixed up.
Error 02 is more a hardware problem. It e.g. yellow and white wire are are
together and short circuit, or if electronics of Autopilot is bad installed with e.g.
long thin wires.
An other typical Err02 error is a bad earthing or incorrect signals e.g. NMEA
signals on the bus.
