2.4 NETWORK START UP AND INITIALISATION
When the NX2 Network gets 12 V power on, the System will perform a Network
initialisation and a system and instrument self test. The display on all digital
instruments first show all segments, then the software version number and the
Nexus Network ID number.
At first power on after installation you will be asked to press any KEY (PrESkey).
This will give each instrument a logical ID number on the Nexus Network. This
(PrESkey) can also come up when a change has been done in the system.
To initialise the instrument, press
SET on all installed digital instruments, one at
the time.
Note: Always wait for the text ”Init OK”
to be displayed, before you press SET
on the next instrument!
The Server automatically gives the first unit ID number 16, then 17 and so on.
The order in which you press
SET is the same order as the instruments will be
given a logical ID number on the Nexus Network.
The example shows that the instrument version number is 2.0 and the given
logical ID number is 16.
The bottom line will write SILVA when the NX2 Multi Control is of version 3.7 or
lower, the same as for Nexus Classic.
On NX2 Multi Control >4.1, Multi XL >1.4 and Autopilot >2.11 Instruments the
bottom line will show the Server ver. no: e.g. 4.7 and the last smaller digit the ID
number of the Network Master/Manager e.g. 0=NX2 Server.
Where 0=Server, 3=AP Servo, 8=Compass Data, 9=Wind Data,
Re-initialising the instrument
If two instruments by mistake have the same ID number, this can cause
disturbance and block the information on the Nexus data bus.
To re-initialise the instrument, press
CLEAR during the power up sequence
when version and ID numbers are displayed.
The display self test is then re-started on all instruments and you will be
asked to press KEY on each instrument as explained above.
Note! If you do not succeed to re-initialise, we suggest you disconnect all but
one instrument with the same ID number, then repeat the above procedure.
