Figure 1 illustrates the major components of the serial option Daystar Nova module. The module provides
means for an external viewing angle adjustment potentiometer (V
RESET and self–test switches at Pins 3 and 5. The external viewing angle adjustment potentiometer should be
connected to the same +5 Volt supply as the display module. RESET and TEST pull down to ground to
activate the function. All three inputs may be left open if not used. The V
preset the viewing angle. The LCD Controllers are microprocessor units (MPU) designed specifically to control
all multiplexing and character decoding functions for the LCD display.
