8.2 Regional settings
The regional settings are primarily used by local base stations to assign special frequencies or transmitter
configurations for certain areas. It is also allowable to add or edit the regions, but this should be done with
caution, as incorrect frequency settings for an area will disable the functionality of the AIS system. Altering
the regional settings is protected by a user password. The Area named HIGH SEA, is the default area and
contains the whole world, except from the other regions, if defined.
Each Region is defined by the following parameters:
Area, defined as North East corner and South West corner.
Two channels used for VHF communications.
Rx/Tx mode is used to restrict the transmission to one of the two channels.
Transitional zone defines the area surrounding an area in order to switch the frequencies in
a step
by step order.
The user is allowed to Add Regions manually, but caution is advised. It is not allowed to delete regions; they
will be deleted on timeout after 24 hours inactivity, if the ship is more than 500 NM away from the region, or
if the region is overwritten. There is a maximum amount of 8 regions in addition to the HIGH SEA region.
