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 Ta>+25C. 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 !

EA DIP204-4NLED

EA DIP204B-4NLW EA DIP204-4HNLED

Both versions -4NLW and -4HNLEDdo have a built-in temperature compensatione; so there's no more need for contrats adjustment while operation anymore.

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 Data Bit 1.) The command "CG RAM Address Set" Adresse Hex Hex 7 6 5 4 3 2 1 0 defines the ASCII code (Bit 3,4,5) and the 0 0 0 $40 0 0 1 0 0 $04 dot line (Bit 0,1,2) of the new character. 0 0 1 $41 0 0 1 0 0 $04 Example demonstrates creating ASCII 0 1 0 $42 0 0 1 0 0 $04 code $00. 0 1 1 $43 0 0 1 0 0 $04 0 1 0 0 0 X X X 1 0 0 $44 1 0 1 0 1 $15 2.) Doing 8 times the write command "Data 1 0 1 $45 0 1 1 1 0 $0E Write" defines line by line the new 1 1 0 $46 0 0 1 0 0 $04 character. 8th. byte stands for the cursor 1 1 1 $47 0 0 0 0 0 $00 line. 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).
