UIF Module NU1
Introduction
The User Interface Module is based on the DCT3 UIF–module. The main
difference is that there is only LCD, keyboard and illumination on the UIF
board. The backlight control circuits are located in the system module.
Electronics
The following sections of circuitry are included on the PCB:
– LCD Display Module
– Keyboard & Display lighting.
– Keyboard switch matrix.
The module comprises a single printed circuit board – loaded with all the
parts for the User Interface Module including LCD, driver, reflector, lightguide and frame.

UIF Module NU1
Functional Description
Circuit Description
The module is connected with 28 pin board to board connector (X130) to
the system board.
The module includes following main functional blocks:
– Keyboard
– Illumination
– LCD interface
Led Drivers
The keyboard and display illumination is achieved by using two transistors in baseband module wired as simple constant current sinks. The Total LED current is fixed by the values of R172 and R171 on the system
module. The different currents to LCD and keyboard are tuned with the
ratios of R185 and R184 on system board.
PAMS Technical Documentation
Keyboard scanning
Keyboard scanning is executed by driving one ROW line to 0 V at time
and data lines are used to read which key is pressed.
LCD module
The LCD module includes the LCD and the display driver. The display
driver can be used with internal or external clock oscillator. If the external
clock is used then the clock frequency is 14.4 kHz.
