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.
