the incoming azimuth angle, the change made will in the first place only affect the XDi where the adjustment is
made, even though several XDi units on the network need the same adjustment.
To avoid the need of making the same adjustment individually on all the XDi units in a system using the same
encoder, XDi has a built-in synchronis
ation function. When leaving the adjust menu, you will be asked via a “Synch
select menu
”, where you want the XDi to send a synchronisation message to all other XDi units on the CAN bus to
make exactly the same adjustments on all.
Highlight YES and press OK to synchronise.
This function will only work when XDi-net and
“Send XDi-net setup synch data” are both active on the CAN bus.
This is activated in the Product Profile or may be set up via the CAN setup menu.
This is a very useful function which reduces the time it takes to adjust a full system containing several XDi
indicators.
11.8 AX1 analogue input adjust
11.8.1
AX1 analogue input
– azimuth/rudder set point 1
In this example, the selected VS profile defines the input for azimuth set point to be an analogue 4-20 mA input, but
this can be changed via the installation menu below. The detailed description of the inputs and functions are found
in the AX1 Chapter.
Data value equal to + or
– 100 %
defines the angle value equal to + or - 100 % rudder angle. %Rudder is not
used in this azimuth indicator. In some cases, when the % data is not used, the value 0 or 1000 is pre-set for both.
Data type and instance
is always fixed
defined in the VS profile.
Name
of the data type (source) may be
changed using the text virtual keyboard
(highlight and press OK).
The following is fixed defined in the VS:
Source:
type of data source
Location:
the slot where AX1 extension
module is installed (or must be installed).
Mode:
input mode is in this case Analogue
input 2.
Status:
active (must be active or else the
interface is not working)
IMPORTANT: If you do not know how the CAN system is set up and configured, you should
select NO to only make the setup locally. That is also why the default selection is NO.
