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 eff ect on the rest of the group members.
The illustration below shows a two station installation. Units on the bridge have their
backlight and damping settings in diff erent SimNet Groups from the units in the cockpit.
If the back light is adjusted on a display in the cockpit, it will change on all displays in the
cockpit. It will not change the light settings on the bridge. If the damping is adjusted on the
AP80 control unit, this will also aff ect damping on the NSE unit in the remote station.
