3.3 User Interface Operation
This section describes the programming/microphone connector and the
controls of the user interface, and the function of the UI board.
Figure 3.5 shows the controls and indicators of the user interface.
Programming/
Microphone
Connector
The PROG/MIC connector can be used to connect a handset or a programming
cable.
TX/RX Switch The TX/RX switch changes the LCD display to show either the transmitter or
the receiver channel. The
TX/RX switch also determines which board will be
programmed by the programming or calibration applications.
The programming application is a program on a PC that is connected to the
base station via the
PROG/MIC connector. The programming application
enables the user to program the base station with the required channels and
subaudible signalling settings. The transmitter and receiver modules are
programmed individually according to the setting of the
TX/RX switch.
The calibration application is a program on a PC that is connected to the
base station via the
PROG/MIC connector. The transmitter and receiver
modules are designed to be totally electronically tuned. No physical tuning
is required, as all tuning is done by electronic trimming. The calibration
application can assist in the tuning of:
■ AD6521 CODEC voltage reference
■ TCXO frequency
■ receiver front end
■ transmitter driver and final gate bias limit
■ transmitter power control
■ deviation and squelch.
