Page 5: General Information
GENERAL INFORMAT ION Introduction This specification describes the serial interface Daystar Nova model 03805–21–0200 4–line supertwist liquid crystal display (LCD) with 40 characters per line. Model Number Designation System 03805 – – Reflective STN LCD 4x40 Format Reserved 0 = No Backlight 0 = Color N/A Parallel Data Input 2 = Serial Data Input... -
Page 6: Logical Structure And Function
LOGICAL STRUCTURE AND FUNCTION Module Block Diagram 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 Adj) at Pin 4, and connections for optional BIAS RESET and self–test switches at Pins 3 and 5. -
Page 7: Lcd Controller
LCD Controller The LCD Controller includes all of the circuitry necessary to take parallel input data and create the necessary control functions and characters. The block diagram of the controller is shown in Figure 2 below. The remaining subparagraphs of Section 2 describe the major function blocks. Address Timing Generation Counter (AC) -
Page 8: Character Generator Rom (Cg Rom)
2.2.6 Character Generator ROM (CG ROM) The CG ROM generates character patterns of 5 X 7 dots from 8 bit character codes. The 192 5 X 7 dot matrix characters are illustrated in Figure 3. Figure 3 Correspondence Between Character Codes and Character Patterns Note: Addresses 00h through 0Fh are reserved for CG RAM Addressing. -
Page 9: Character Generator Ram (Cg Ram)
2.2.7 Character Generator RAM (CG RAM) The CG RAM allows the user to define 8 types of 5 X 7 character patterns. Figure 4 shows the relationship between CG RAM addresses and data patterns (Refer to Set CG RAM Address and Write to CG or DD RAM instructions). -
Page 10: Theory Of Operation
THEORY OF OPERAT ION The serial input option was designed to allow users to send data and control codes to the display module via the industry standard RS–232C serial interface. This follows the interface protocol of the parallel input Daystar Nova display modules with few exceptions. -
Page 11: Power-Up Sequence
Power–up Sequence Upon power–up, the serial Daystar Nova display module is automatically initialized to the format defined by the jumper settings and default values shown in Figure 6. The power–up sequence takes about 0.5 second. Baud rate: Jumper defined (per section 4.2) Parity bit present: "... -

Page 15: Down-Loadable Special Characters
Down–Loadable Special Characters An added feature of the serial input module is the inclusion of a group of 206 special characters stored in its memory. These supplement the character library of the LCD module and may be easily down loaded (up to eight at a time) into the CG RAM of the display module for use in one display frame of the display. - Page 16 Figure 10 Down–loadable Special Characters Industrial Electronic Engineers, Inc.

Page 17: Self-Test
Self–test The serial input display module can be operated independently from the host by using the "Self–test" option. 1. Check the multiplex jumper for proper setting (Section 4.2). 2. Connect a +5V power supply and potentiometer as discussed in Paragraph 2.1 and Figure 1. 3. -
