BACKLIGHT
Using the LED backlight requires an current source or external current-limiting resistor. Forward
voltage for yellow/green backlight is 3.9~4.2V and for white LED backlight is 3.0~3.6V. Please take
care of derating for T
a
>+25°C.
Note: - Do never connect backlight direct to 5V; this may destroy backlight immediately !
- Blue-white displays do always need a backlight for contrast (min. 5mA).

CHARACTER SET
A full character set is built in already.
Additionally to that 8 more characters can
be defined individually.
CONTRAST ADJUSTMENT
Pin 3 requires driving voltage for contrast
VEE. Adjustment can be done by external
potentiometer for example.
Note: In contrast to many other
dotmatrix lcd modules input is
supplied with VDD level here !

Both versions -4NLW and -4HNLEDdo

CREATING YOUR OWN CHARACTERS
All these character display modules got the feature to create 8 own characters (ASCII Codes 0..7) in
addition to the 240 ROM fixed codes.
Set CG RAM Address

1.) The command "CG RAM Address Set"
Bit
Adresse

defines the ASCII code (Bit 3,4,5) and the
7 6 5 4 3 2 1 0
dot line (Bit 0,1,2) of the new character.

X X X
1 0 0 $44

Write" defines line by line the new

0 0 1 0 0 $04
line.
1 1 1 $47

3.) The new defined character can be used
as a "normal" ASCII code (0..7); use with "DD RAM Address Set" and "Data Write".

DIMENSIONS
ATTENTION
handling precautions!
all dimensions are in mm
SERIAL MODE
Factory set for interface is parallel with 4 bit or 8 bit data bus. Alternative module can be programmes
with serial data stream. For that solder link
4/8
has to be opened and closed to
SPI
side. Specification
for serial operation mode is written down in user manual for KS0073:
http://www.lcd-module.de/eng/
pdf/zubehoer/ks0073.pdf
ADAPTOR PCB
The adaptor pcb EA 9907-DIP is made for a quick
function test for all DIP modules. This interface board
provides the standard dotmatrix pinout with 1x14,
1x16, 2x7 and 2x8 pins (0.1" pitch).
