Fleet Map
The radio configuration screen allows for the entry
and storage of ten system/fleet map configurations.
The fleet map is a plan of how the radio defines the
data that is passed between the radio and the central
controller. The fleet map is made up of prefixes and
size codes. Each fleet map can have up to eight size
codes. The value of the prefix field is an index into
the fleet map to the size code. A single letter
designates each size code.
NOTE
Fleet Map information should be obtained
from the System Manager. It also should be
resident within the customer maintained data
base for each system.
To enter information in the Radio Configuration
screen, first obtain the system ID from the 10-digit
hexadecimal number on the user label. Then,
determine the size code configuration of the system
from the system manager. Enter the system ID and
the size code letters to the right of the system ID.
Enter the system configuration information before
beginning a test to decode fleet, subfleet, and unit
ID information.
The system ID and size codes of the radio being
tested make up a fleet map. The fleet map must be
entered accurately in order for the analyzer to
decode the ISW transmitted by the radio.
Example of a Trunk I Fleet Map
The first entered item is the system ID. The radio
should have a user label that contains a 10-digit
hexadecimal number. The first four numbers are the
system ID, the next three are the fleet ID, and the
last three the radio ID, (Unit ID).
For example, suppose the user label has the
following hexadecimal number:
0A09400001
This represents:
System ID Fleet ID Individual ID
0A09 400 001
The fleet prefix is the first number of the three digit
hexadecimal fleet ID. The value of the prefix field
is an index into the fleet map of a given system for
looking up the size code value.
Each trunked fleet map contains a set of eight size
codes that is indexed by the prefix value. A single
letter designates each size code.
