POWER UP CONDITION
Immediately upon power up the following is set:
The module is in the text mode.
The screen will have a message printed as follows:

This message indicates the hardware test has passed
successfully. The "mm-dd-yy" indicates the date the

mately 250 mS to complete. It is suggested the user wait for
that time period to elapse before entering data.

INTERFACING
W1 JUMPER
Shunt 1 pair of pins only on jumper W1 to select serial
interface baud rate, parallel interface operation, or self-test
functions. Shunt both OPT 1 and STEST to run demo.
W2 JUMPER
The W2 jumper selects the serial handshake busy line from
the host computer to the display for control of data flow from
the display. On Jumper W2, select “CTS” for host RTS to
display CTS handshaking, or “DSR” for host DTR to display
DSR handshaking. Selection does not affect parallel
interface operation.

TEXT FUNCTIONS
NO FUNCTION.
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.
HORIZONTAL TAB: Moves the cursor 1 column to the right. Will wrap
around at 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.
LINE FEED: Moves cursor down one row while remaining in same column
position. If mode is set to SCROLL, and 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, the cursor
will wrap to the first row.
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.
CLEAR SCREEN: Fill the screen with blank characters, cursor moves to
HOME position.
CARRIAGE RETURN: Moves cursor to the first column of the present row.
HOME CURSOR: Moves cursor to the 1st character position of the 1st row,
the HOME position.
NO OPERATION.
NO OPERATION.
POSITION CURSOR: Moves cursor to a specified column, row address
depending upon next 2 bytes sent. The format is column, row.
SELECT CURSOR: Following byte selects cursor style
*
01 = Blinking Underbar
02 = Non-Blinking Underbar
03 = Blinking Block
04 = Cursor not Visible
NO OPERATION.
SELECT CHARACTER FONT: Following byte selects one of 4 character
generator fonts:
*
00 = ASCII, standard and inverse
01 = International
02 = International and Katakana
03 = International and Cyrillic
Set 8th data bit to logic "1". This is a useful command for programmers who
want to mix characters from both top and bottom of character set without
calculating offsets. (For example, using reverse video with the default font.)
NO OPERATION.
NO OPERATION.
NO OPERATION.
Set 8th data bit to logic "0". This disables the
previous command (15h).
RESERVED, do not use.
See ESCAPE control codes.
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 spaces.
SET TO AUTO WRAP 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.
BLANK DISPLAY: The display is blanked, but display memory is maintained
and new data can be entered.
UNBLANK DISPLAY: The display is restored/turned to active state.

COMMAND SET, GRAPHIC MODE
(SOFTWARE INSTRUCTIONS)
CURSOR LOCATION
- All cursor locations are based upon Pixel location - NOT - character column and row locations. The
upper left hand corner is 000,000 (X, Y) while the lower right hand corner is 127, 063 (X, Y). The cursor auto-increments
based upon the character font size by the width of the font. The cursor is not visible in graphic logic.
WRITE LOGIC
- Within most commands, the WRITE 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 back ground 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:
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
Refer to character set tables for supported characters and fonts.
NOTE:
The LOGIC byte and FONT byte are sent in ASCII format.
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 are shown in the graphic sequences only for clarity and must not occur in the actual commands transmitted
to the panel.
GRAPHIC FUNCTIONS

GRAPHIC FUNCTIONS
TEXT WRITE: Logic byte (l), font byte (f), x, y starting address, ASCII text. Wrap around will occur.
ESC B l f xxx yyy aaaa..aaaa ESC \
CLEAR SCREEN: This command will clear the graphic screen to all pixels off (logic 0).
ESC C
SET PIXEL COMMAND: Logic byte (l), x, y pixel address, end of data delimiter.
ESC D l xxx yyy ESC \

ESC D l xxx yyy xxx yyy .......ESC \

SET TEXT MODE:

SET GRAPHICS MODE:

DRAW ELLIPSE: Logic byte, major axis intercept offset, minor axis intercept offset (axis's intercept offset is measured in
pixels from the center point), x, y center point, from angle theta (t), in degrees, to phi (p). A complete rotation would be from
001 to 360.
ESC H l mmm www xxx yyy ttt ppp
WRITE GRAPHIC IMAGE: Logic byte 1, y1 (upper left hand corner), 2, y2 (width and height), data.
ESC I l xxx yyy xxx yyy ddd ....
X1 start coordinate and X2 width must both be multiples of 8. The number of data bytes transmitted must be equal to (X2
width / 8)* Y2 height. The first data byte transmitted will map into the 8 pixels on the top line in the upper left hand corner of
the image with the least significant bit at the left and the most significant bit at the right. Successive bytes will write to the
next byte to the right. When all bytes are written for this line, the next byte will map into the left most byte of the next line
down.
