nervous system (fig. 2-30). It ensures system integrity
and reliability by monitoring and regulating each
component’s activities. It is used to set all adjustable
parameters that determine PRF, antenna position, and
all processing thresholds. The UCP is tasked with
resolving operational conflicts, such as load control
when overload conditions occur. The UCP executes
commands via a narrowband link with the RPG (fig.
2-25). It manages both an "application" function and a
"system console" function. These functions control
hardware and software throughout the entire system.
Application Terminal
The applications terminal manipulates or changes
hardware performance. It controls RDA and RPG
operations including product generation, distribution,
and storage. It manages internal communications and
allows the isolation of individual components, or the
disconnection of any user. It controls all message
traffic between individual users and the UCP operator,
and may restrict system access. The UCP operator can
monitor system status to ensure smooth operation.
System Console Terminal
This function primarily affects software
performance. It provides user interface to the RPG.
Specific operations include start-up and shutdown of
application software, executing system diagnostics,
and performing maintenance operations.
The UCP normally consists of two monochrome
monitors and two keyboards (one for each function).
Some UCPs, however, use only a single
monitor/keyboard combination that toggles back and
fourth between application and system control
functions.
SYSTEM USERS
The WSR-88D is uniquely supported by a
triagency program that includes the Department of
Figure 2-30.—WSR-88D Unit Control Position (UCP).
