PTRL & RXRL LCD
8 / 44 User Manual Rev. 1.2 - 31/01/05
Both the PTRL-LCD and the RXRL-LCD were designed in a modular way: the different
functions are executed by modules connected directly with male and female
connectors or with flat cables with connectors at both ends. This type of design makes
the maintenance and the possible replacement of modules an easy operation.
The microprocessor system includes an LCD display and series of push-buttons
that enable the interaction with the user, and implements the following functionsfor
the transmitter:
• Setting of the output power
• Setting of the working frequency
• Activation and switch off of the power distribution
• Measurement and display of the working parameters of the transmitter
• Communication with external devices
These functions are implemented for the receiver:
• Display of the modulation
• Setting of the working frequency
• Setting of the muting
• Measurement and display of the working parameters of the receiver
• Communication with external devices
The system of the management software is composed of several menus.
The user can navigate between the different submenus by using four push-buttons:
ESC, LEFT/HIGH, RIGHT/LOW, and ENTER.
The status of the unit is indicated by four LEDs which are present on the front pannel:
• ON, LOCK, FOLDBACK, RF MUTE for the PTRL LCD.
• ON, LOCK, PILOT, MUTE for the RXRL LCD.
Both the transmitter and the receiver have an input for the external 24 Vcc 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.
