Minimum rudder
This parameter fi lters small rudder commands to prevent high rudder activity.
Some boats may have a tendency to not respond to small rudder commands around the
“course keeping” position because of a small rudder, a rudder deadband, whirls/disturbance of
the water-stream passing the rudder or it is a single nozzle water jet boat.
By increasing the Minimum rudder parameter you may improve the course keeping
performance on some boats. This will however increase the rudder activity.
Minimum wind angle to port and starboard
These parameters should be set identical to the minimum apparent wind angle that will keep
the sails from stalling and maintain boat speed. The parameters will vary from boat to boat.
The settings are used for the tack-prevent function. They also apply when the autopilot is
operating in WindNAV mode.
You can select diff erent minimum wind angles for port and starboard. The diff erence between
port and starboard will be taken into account when calculating the Distance To Turn (DTT).
Navigation change limit
This parameter defi nes the maximum course change that the autopilot is allowed to make
when the NSO-II is following a route (NAV steering).
If the required course change to the next waypoint in a route is more than the set limit, you
are prompted and must acknowledge the course change before the autopilot will turn the
vessel.
CZone setup
In order to communicate with the CZone modules connected to the network, the NSO-II
must be assigned a unique CZone Display Dipswitch setting.
The functionality of the CZone system is determined by the CZone Confi g File (.zcf ), which
is stored on all CZone modules and supported Simrad displays, such as the NSO-II. The fi le is
created using the CZone Confi guration Tool, a specialised PC application available from BEP
Marine Ltd, and associated CZone distributors.
The NSO-II system provides a means to load the Confi g fi le, as well as apply updates to
module fi rmware, removing the need to take a laptop computer aboard the vessel.
Enabling CZone functionality
If the Czone device(s) are not automatically detected, it is possible to manually enable CZone.
Once CZone is enabled, an addtional CZone menu appears at the bottom of the Settings
page.
Assigning the dipswitch setting
Every Simrad product capable of controlling and viewing CZone devices must be assigned
a virtual dipswitch setting. This setting is unique for each device. Typically it is set after the
confi g fi le already exists on the CZone system, but it may also be set in advance. To do so,
access the CZone menu on the Settings page.
When the confi g is already available on the network, it will immediately commence
uploading to the NSO-II once the dipswitch is set. Allow this to complete, without
interruption.
