Authorization
The Authorization tab folder displays the current
authorization status of the display.
If the authorization state is valid the following
message is displayed at the top of the tab folder:
The system is fully authorized.
The authorization folder displays a five digit
system PIN, which is encrypted when the
system is initially commissioned. The PIN is
contained on the Sperry Security Block, which is
provided and installed when the system is
commissioned.
The Sperry Security Block also contains the
product type identifier for the node, (e.g. Total
Watch or Chart Radar). This is shown in the
Product Type of This Node field.
For a multi-node system, in addition to the
security block, a security string is placed on all
nodes in the system. The security string
contains an encryption of the following:

the System PIN

the product types in the system and number
of nodes for each product type (e.g. 2
Radars and 1 ECDIS).

the list of features that have been
purchased. Any features purchased from the system provider are
shown in the
Purchased Features field.
Once a feature is purchased, it will be available on all nodes which are of a
compatible product type.
