SimNet groups
The SimNet Group function is used to control parameter settings, either globally or in groups
of units. The function is used on larger vessels where several SimNet units are connected via
the network. By assigning several units to the same group, a parameter update on one unit
will have the same effect on the rest of the group members.
The illustration below shows a two station installation. Units in the Remote Station have their
backlight and damping settings in different SimNet Groups from the units on the Main Bridge.
If the back light is adjusted on a display on the Main Bridge, it will change on all displays on
the Main Bridge. It will not change the light settings in the Remote Station. If the damping is
adjusted on the AP80 control unit, this will not affect damping on the NSE unit in the remote
station.

Master systems
The international standard for heading control systems (ISO 11674/ISO 16329) requires
controlled command transfer when remote stations are provided. The delegation of control
to the remote station and the return of control shall be incorporated in the autopilot system,
and shall avoid unintended operation from a remote station.
To fulfill this requirement the AP70/AP80 system includes a Master function. This is used in
larger Wheelmarked systems where you permanently want to control command transfer to
remote stations.
In a Master system, one steering station is defined as the Master station. There can be several
