The microprocessor system includes an LCD display and an encoder that enable
the interaction with the user, and implements the following functions for the
transmitter:
•
Display of the modulation
•
Setting of the output power
•
Setting of the working frequency
•
Power Good feature (User-selectable output power alarm threshold).
•
Measurement and display of the working parameters of the transmitter
•
Communications with external devices such as programming systems, or
telemetry systems, via SERVICE serial interface.
These functions are implemented for the receiver:
•
Display of the modulation
•
Setting of the working frequency
•
Setting of the muting threshold
•
Measurement and display of the working parameters of the receiver
•
Communications with external devices such as programming systems, or
telemetry systems, via SERVICE serial interface.
The
URPT/MIC
and
URPR/MIC
management firmware is based on a menu system.
User has four navigation buttons available to browse submenus:
ESC

ENTER
.
The status of the unit is indicated by four LEDs which are present on the front
pannel:
•
ENCODER ON, POWER ON, PLL LOCK, PWR OUT FOLDBACK, RF MUTE
for
URPT/MIC
.
•
ENCODER PRESENT, POWER ON, PLL LOCK, PILOT PRESENT, AUDIO
MUTE for
URPR/MIC
.
Both the transmitter and the receiver, through the SERVICE connector, have an
input for the external 12 or 24 V
DC
supply. This auxiliary supply source, that can
be realized by the user with the help of rescue batteries, is automatically used in
case of AC voltage absence.
