DESCRIPTION OF SIGNALS PIN NO FUNCTION DESCRIPTION 1,3,5,7 9,11,13 15 D0 - D7 (Data Bus) Data written to and read from (input/output) the display unit through an 8 bit bi-directional data bus. 17 WRITE (WR) (input) Write data on low to high trans. 21 READ (RD) (input) Read data while low. N/C Not connected. 23 RESET (input) Reset display to power-up condition when low, operate while high. 19 US (Unit Select) (input) Read and Write commands only influence display while US is low. 25 BLANK (BL) (input) Blank display while BL is low but maintain cursor and data. 4 BRIGHT/DIM (input) Display at full brightness when high or half brightness when low. 24 BUSY (BU) (output) When BUSY is high, no further data or commands should be given. GROUND Common to both power supply input and host data interface. DATA PRESENT (DP) (output) Data is ready to be read when the DATA PRESENT signal is high. 6,8,12, 14,16, 18,20,22 2,26 10 See timing diagram below. INPUT/OUTPUT TIMING DIAGRAM, J2 BU - DP - WR - RD - US FUNCTION L-X-↑-H-L Write character or control code. X-H-H-L-L Read data from display while low. X-X-X-X-H Input/Output inhibited. Logic Level: L = 0.0V min. to 0.8V max. H = 2.2V min. to 5.0V max. X = Don’t Care NOTE - Input load is one 74HCT type input with 4.7k to Vcc. Outputs are 74HC type. Once data write is complete, BUSY signal is output. BUSY signal = “1” during data disposition and while the communication buffer is full. DATA WRITE When WR changes from “0” to “1” while US = “0” and RD = “1”, data is latched. All data and character codes are shown in the Command Set section. WRITE signal should be normally high, strobe low then high when writing. DATA READ When RD = “0” while US = “0”, WR = “1”, and DP = “H”, data may be read by the host. READ signal should be normally high, low when reading. Document Number: 37074 Revision 14-Mar-02 www.vishay.com 3 PDS-500/-1 Vishay Dale SERIAL INTERFACE J3, SERIAL INTERFACE CONNECTOR.

A brief listing of the available commands and their description follows. Text mode operation is not true text mode, but rather simulated in graphics mode. Text and Graphics may be mixed on the same screen. HEX CODE NUMBER OF BYTES 00-07 TEXT FUNCTIONS No function 08 1 Back Space Cursor: Moves the cursor 1 column to the left in the current row. If the cursor is at the 1st column it will move to the end of the previous line. 09 1 Horizontal Tab: Moves the cursor 1 column to the right. Will wrap around until the end of the screen. If mode is set to SCROLL then the screen will scroll up one line at the last character position of the last row, if not in SCROLL mode then the cursor will wrap to the HOME position. 0A 1 Line Feed: Moves cursor down one row while remaining in same column position. If mode is set to SCROLL, when the cursor is at bottom row of screen, the screen will move (scroll) up 1 row and bottom row will be cleared (filled with spaces) when line feed is invoked. If not in SCROLL mode then the cursor will wrap to the first row. 0B 1 Vertical Tab: Moves cursor up one row while remaining in the same column position. The cursor will wrap to the bottom row after the top row. 0C 1 Clear Screen: Fill the screen with blank characters, cursor moves to HOME position. 0D 1 Carriage Return: Moves cursor to the first column of the present row. 0E 1 Home Cursor: Moves cursor to the 1st character position of the 1st row, the HOME position. 0F NO OPERATION 10 NO OPERATION 11 3 Position Cursor: Moves cursor to a specified column, row address depending upon next 2 bytes sent. The format is x,y or col, row. The upper left corner is 0,0. 12 2 Select Cursor: Following byte selects cursor style: *01h = Blinking Underbar 02h = Non-Blinking Underbar 03h = Blinking Block 04h = Non-Display Cursor 14 2 Select Character Font: Following byte selects one of 4 character generator fonts: 01h = font 1: 4x5 character in 5x6 block *02h = font 2: 5x7 character in 6x8 block 03h = font 3: 10x14 character in 12x16 block The cursor is moved to the home position when changing fonts. 15 1 Select reverse video characters (black on orange) 13 NO OPERATION 16 NO OPERATION 17 NO OPERATION 18 NO OPERATION 19 1 *Select normal video characters (orange on black). This disables the previous command (15h). 1A RESERVED, do not use 1B see ESCAPE control codes 1C 1 Set to Scroll Mode: Sets the display mode so that whenever the cursor reaches the last position in the last column or a line feed occurs while cursor is on last row, the screen will scroll up one row. The top row of data will be lost and the bottom row of the display will be erased. 1D 1 *Set to AutoWrap Mode: In this mode, the cursor will automatically wrap around to the next row. When the last character position on the screen is reached, the cursor will return to HOME position. 1E 1 Blank Display: The display is blanked but display memory is maintained and new data can be entered. 1F 1 NOTE:”*” indicates power up default Document Number: 37074 Revision 14-Mar-02 *UnBlank Display: The display is restored/turned to active state. www.vishay.com 5 PDS-500/-1 Vishay Dale COMMAND SET, GRAPHIC MODE (Software Instructions) CURSOR LOCATION All graphic cursor locations are based upon pixel location - NOT - character column and row locations. For example, the upper left hand corner is 000,000 (X,Y) while the lower right hand corner might be 127,063 (X,Y). The cursor indicates the upper left corner of the location of the character. The cursor auto-increments based upon the character font size by the width of the font. The graphic mode cursor is not visible, it may be desirable to turn-off the text mode cursor when performing graphics operations. WRITE MODE Within most commands, the LOGIC BYTE must be included: 0 = SET PIXELS (turn-on foreground pixels) 1 = XOR PIXELS (invert foreground pixels) 2 = RESET PIXELS (turn-off foreground pixels) 3 = OVERWRITE (turn-on foreground and turn-off background pixels, image write and graphic text commands only) 4 = REVERSE VIDEO OVERWRITE (turn-off foreground and turn-on background pixels, image write and graphic text commands only) FONT SIZE The FONT SIZE must be written before text is written. There are three standard fonts included in the graphics mode. Refer to font tables for supported characters and fonts. 1 = FONT 1, a 4 x 5 character in a 5 x 6 block 2 = FONT 2, a 5 x 7 character in a 6 x 8 block 3 = FONT 3, a 10 x 14 character in a 12 x 16 block. NOTE- In graphics mode, the LOGIC byte and FONT byte are sent in ASCII format. For example, to select font 2, send 32h -NOT 02h. DATA FORMAT All addresses must be sent in ASCII format. Column and row positions begin at the upper left hand corner at address 000,000 (X,Y). A pixel address consists of a column address followed by row address. Addresses are sent to the panel as a three character ASCII sequence for column (x) followed by a three character ASCII sequence for row (y). An example is the upper left hand pixel is 000,000 while the lower right hand corner is 127,063. NOTE: Spaces and commas are shown in the graphic sequences only for clarity and must not occur in the actual commands transmitted to the panel. www.vishay.com 6 Document Number: 37074 Revision 14-Mar-02 PDS-500/-1 Vishay Dale GRAPHIC COMMANDS HEX CODE GRAPHIC FUNCTIONS 1B,41 Fill Area: logic byte, X1, Y1 (upper left corner), X2, Y2 (lower right corner).

Page is a three byte value (ASCII representation). Default is page 000. See table for number of pages supported in each of the display formats. DISPLAY FORMAT FONT NUMBER OF WIDTH HEIGHT DATA BYTES 1 6 5 bits 6 lines 2 8 6 bits 8 lines 3 32 12 bits 16 lines (1 byte/line) (1 byte/line) (2 bytes/line) NUMBER OF PAGES 128 x 32 128 (000-127) 128 x 64 64 (000-063) 192 x 64 42 (000-041) 256 x 64 32 (000-031) 320 x 64 25 (000-024) SET WRITE PAGE: PAGE ESC Q ppp Sets the active read/write page of video RAM on which all subsequent commands operate. Default is page 000. The write page may be different than the display page. Pages may be written while another page is displayed, invisible to the viewer. For fonts 1 and 2, each byte represents a character line. The first byte is the top line of the character. Subsequent bytes map each line of the character. Typically, the right column and the bottom row of a character are blank for spaces between characters. For font 3, two bytes (a word value) are required to represent each character line. The first byte represents the left part of the character, the second byte represents the right part of the character. The first word value is the top line of the character, subsequent words map each line of the character. Typically, the left and right columns and top and bottom rows of a character are blank for spaces between characters. Graphical representation of character data: Combine Pages: logic byte, p1 (source page 1), p2 (source page 2), p3 (destination page). top ESC R l ppp ppp ppp bottom Combines graphic information on source pages using logic write modes 0, 1, or 2 and places that information on the destination page. Text Write: logic byte (l), font byte (f), x,y starting address, ASCII text. Wrap around will occur. ESC T l f xxx yyy aaaa..aaaa ESC \ UPLOAD CUSTOM CHARACTER: FONT, DATA ESC U f ddd... The custom character becomes ASCII value FFh and replaces any character which may be mapped at that location. One custom character is allowed for each font. To restore the original default character mapped at location FFh, upload a blank character where all data bytes are zero. To use multiple custom characters in a single font, upload new data as needed. Custom characters previously printed to the screen will not change when a new character is loaded. font3 font2 font1 lsb x x x x x x msb lsb x x x x x x msb lsb x x x x x x msb lsb x x x x x x msb lsb x x x x x x msb lsb x x x x x x msb Content he factory for free support to aid in generating character data.
