GENERAL
The EA eDIP series of displays are the world’s first displays with integrated intelligence. In addition
to a variety of integrated fonts that can be used with pixel accuracy, they offer a whole range of
sophisticated graphics functions.
They are controlled via one of the 3 integrated interfaces: RS-232, SPI or I²C. The displays are
“programmed” by means of high-level language-type graphics commands. There is no longer any
need for the time-consumingprogramming of character sets and graphics routines. The ease of use
of this display with its touch panel dramatically reduces development times.
HARDWARE
The display is designed to work at an operating voltage between +3.3V to +5V.
Data transfer is either serial and asynchronous in RS-232 format or synchronous via the SPI or I²C
specification. To improve data security, a simple protocol is used for all types of transfer.
ANALOGUE TOUCH PANEL
All versions are also available with an integrated touch panel: You can make entries and menu or bar
graph settings by touching the display. The labeling of the “keys” is flexible and can also be changed
during runtime (different languages, icons). The drawing of the individual “keys” and the labeling is
handled by the integrated software.
LED ILLUMINATION
All displays are equipped with modern, energy-saving LED illumination. Brightness can be varied
0~100% by command.
In24-houroperation,theilluminationshouldbedimmedorswitchedoffasoftenaspossibletoincrease
their lifetime.
SOFTWARE
Thisdisplayisprogrammedbymeansofcommands, suchasDrawarectanglefrom(0,0)to(319,239).
No additional software or drivers are required. Strings and images can be placed withpixel accuracy.
Text and graphics can be combined at any time. Different character sets can be used at same time.
Each character set and the images can be zoomed from 2 to 8 times and rotated in 90° steps. With the
largest character set, the words and numbers displayed will fill the screen.
ACCESSORIES
Evaluation-Board (Programmer) for internal data flash memory
The display is shipped fully programmed and with all fonts. The additional Evaluation-Board is thus
generally not required.
However, if the internal character sets have to be changed or extended, or if images or macros have
to be stored internally, the Evaluation-Board EA 9777-2USB, which is available as an accessory, will
burn the data/images you have created into the on-board data flash memory (4 MB) permanently.
The Evaluation-Board runs under Windows and is connected to the PC’s USB interface. It is shipped
with an interface cable and the installation software. The Evaluation-Board is equipped with serveral
LEDs, pushbottons and potentiometer to test all peripherial modes of the eDIP.
Interface-Expansion for Evaluation-Board:
Wtih the expansion EA 9777-2PE for the Evaluation-Board all interfaces of the display are made
available with the help from small adapter boards: RS-232, RS-485, SPI, I²C, RS-232 (CMOS level).
Further information you will find in the datasheet of the Evalution-Board.

RTS/CTS handshake lines are not required. The required control is
taken over by the integrated software protocol (see pages 10 and 11).
Note:
The pins BAUD 0 to 2, ADR 0 to 2, DPOM,
DPROT and TEST/SBUF have an internal
pullup, which is why only the LO level
(0=GND) is to be actively applied. These
pins must be left open for a Hi level.
For RS232 operation (without
addressing) the pins ADR 0 to ADR 2
must be left open.
On pin 20 (SBUF) the display indicates
with a low level that data is ready to be
retrieved from the internal send buffer.
The line can be connected to an interrupt
input of the host system, for example.

APPLICATION EXAMPLE „REAL“ RS-232 INTERFACE
The eDIP fits for direct
connection to a RS-232
interface with CMOS
level (VDD).
If you have an interface
with 12V level, an
external levelshifter is
needed
application example
APPLICATION EXAMPLE: RS-485 INTERFACE
With an external converter (e.g.
SN75176), the EA eDIP can be
connected to a 2-wire RS-485
bus. Large distances of up to
1200
m
can thus be
implemented (remote display).
Several EA eDIP displays can
be operated on a single RS-485
bus by setting addresses.
application example
Addressing:
- Up to eight hardware addresses (0 to 7) can be set by means of Pins ADR0..ADR2
- The eDIP with the address 7 is selected and ready to receive after power-on.
- The eDIPS with the addresses 0 to 6 are deselcted after power-on
- Up to 246 further software addresses can be set by means of the ‘#KA adr’ command in the power-on macro (set eDIP
externally to address 0)
APPLICATION EXAMPLE: USB INTERFACE
With an external converter (e.g. FT232R) from FTDI the eDIP can be connected to an USB-Bus.
Virtual-COM-Port drivers are available for different Systems on the FTDI Homepage:

DATA TRANSFER SPI
Write operation: a clock rate up to 200 kHz is allowed
without any stop. Together with a pause of 100 µs
between every data byte a clock rate up to 3 MHz can
be reached.
Read operation: to read data (e.g. the „ACK“ byte) a
dummy byte (e.g . 0xFF) need to be sent.
Note that the EA eDIP for internal operation does need
a short time before providing the data; therefore a short
pause of min. 6µs (no activity of CLK line) is needed for
each byte.

ANALOGUE INPUT AIN1 AND AIN2 (PIN 23+24)
For analogue measurement 2 inputs with a range of 0..VDD are available. Each input is grounded
(GND) and DC impedance is 1MΩ. Please make sure that only positive voltages will be supplied
there. Internal resolution is 10 Bit, equal to a 3-digit DVM modul. Linearity (after adjustment) is around
0.5%.
Adjustment
Analogue inputs are not calibrated when shipped out. A procedure for adjustment may be like that:
1.) Put a well known voltage within a range of 2-VDD to analogue input (example: 3,0V, AIN1)
2.) Run command for calibration (see page 15). Example: „ESC V @ 1 3000“.
Each input query can be done via serial interface or directly shown on display (as digits or bargraph
in various colors and sizes).
BestwayfordirectvisualisationareProcess-macrosoroneofAnalogue-macros(e.g. startingatevery
voltage change, or above/below a limit).
Both input lines are scaleable from 0 to 9999.9. Scaling will be done via definition at 2 voltages
„value1=string1;value2=string2“ (see table on page 16).
DIGITAL INPUT AND OUTPUT
The EA eDIP is featured with 8 digital input and 8 digital output lines (CMOS level,
grounded).
8 outputs (Pin 25-32)
Each line can be controlled individually using the „ESC Y W“ command. A
maximum current of 10mA can be switched per line. This give the opportunity to
drive a low power LED in direct way. To source higher current please use an
external transistor.
8 inputs (Pin 33-40)
Each input provides an internal 20..50 kΩ pull-up resistor, so it is possible toconnect a key
or switch directly between input and GND. The inputs can be queried and evaluated
directly via the serial interface („ESC Y R“).
In addition to that every port change may start an individual port - or bit- macro(see p. 28).
The command "ESC Y A 1" activates automatic port query. Every alteration of inputs firstly calls bit
macros and afterwards port macros. If there is no definied macro, the new status is transfered into the
send buffer (refer to p. 19).
Note: The logic circuitry is designed for slow operations; in other words, more than 3 changes per
second cannot be easily executed.
EXTENDED OUTPUTS
It is possible to connect 1 to 32 chips like 74HC4094 to the eDIP (OUT1...OUT3), this is why it is
attainable to have 8 to 256 additional outputs. The command "ESC Y E n1 n2 n3" (see p. 17) provides
a comfortable way to control the outputs.

EXTERNAL KEYBOARD
Akeyboard(anythingfromindividualkeystoa8x8matrixkeyboard)canbeconnectedtotheI/O-ports.
The command ‘ESC Y M n1 n2 n3’ defines the count of input lines (n1=1..8) and output lines (n2=1..8).
n3setdebouncefunctionwith10mssteps(n3=0..15). Pleasenotethatcountofdigitalinputandoutput
lines will be reduced while connecting an external keyboard at the same port.
Each key is connected with 1 output and 1 input. All inputs are terminated with a 20..50kΩ pull-up
resistor.Fordouble-keytrokefunctiondecouplingofoutputsisnecessary.Forthatpleaseuseschottky
diodes (e.g. BAT 46).
Transmitting the keystrokes
At each keystroke, the associated key number (1..64) is transmitted or if a corresponding Matrix-
Macro is defined, Matrix-Macro will be started. The release of the key is not transmitted. If the release
of the key is to be transmitted as well, this can be done by defining Matrix-Macro no. 0.
(see page 17: Responses of EA eDIP)
Calculating of key numbers:
Key_number = (output-1) * count_of_inputs + input(output = MOx, input = MIx).
Examples
- 2x2 matrix: Command ‘ESC Y M 2 2 ..’ defines the 2x2 matrix. Keypad will need input lines MI1, MI2
and output lines MO1, MO2. Output lines are decoupled by diodes; this is for double
keystrokes necessary. 6 input and 6 output lines remain free for other requirements.
- 1x4 matrix: Command ‘ESC Y M 1 4 ..’ defines the 1x4 matrix. Keypad will need output lines
MO1..MO4 and a single input line MI1. With that connection 7 input and 4 output lines
remain free for other requirements.
- 4x0 matrix: Using one single output only (physically 4x1 Matrix), all keys can switch to GND. So no
output line is necessary and comman ‘ESC Y M 4 0 ..’ defines 4 input lines onyl. With that
connection 4 input and 8 output lines remain free for other requirements.
- 4x4 matrix: Command ‘ESC Y M 4 4 ..’ defines the 4x4 matrix. Keypad will need input lines MI1..MI4
and output lines MO1..MO4. Output lines are decoupled by diodes; this is for double
keystrokes necessary. 4 input and 4 output lines remain free for other requirements.

Theprotocolhasanidenticalstructureforall3interfacetypes:RS-232,SPIandI²C.Eachdatatransfer
is embedded in a fixed frame with a checksum (protocol package). The EA eDIPTFT32-A
acknowledges this package with the character <ACK> (=$06) on successful receipt or <NAK> (=$15)
intheeventofanincorrectchecksumorreceivebufferoverflow.Inthecaseof<NAK>,
the entire package is rejected and must be sent again.
Receiving the <ACK> byte means only that the protocol package is ok,
there is no syntax check for the command.
Note: it is neccessary to read the <ACK> byte in any case. If the host
computer does not receive an acknowledgment, at least one byte is lost.
In this case, the set timeout has to elapse before the package is sent
again. The raw data volume per package is limited to 255 bytes (len <=
255). Commands longer than 255 bytes (e.g. Load image ESC UL...)
must be divided up between a number of packages. All data in the
packages are compiled again after being correctly received by the EA
eDIP.
DEACTIVATING THE SMALL PROTOCOL
For tests the protocol can be switched off with an L level at
pin17=DPROT.Innormaloperation,however,youareurgentlyadvised
toactivatetheprotocol.Ifyoudonot,anyoverflowofthereceivebufferwill
not be detected.
BUILDING THE SMALL PROTOCOL PACKAGES

The user data is transferred framed by <DC1>,
the number of bytes (len) and the checksum
(bcc). The display responds with <ACK>.

setting is a package size with up to 128 bytes of
user data. The timeout can be set in increments
of 1/100 seconds. The timeout is activated
when individual bytes get lost. The entire
package then has to be sent again.

TERMINAL MODE
When you switch the unit on, the cursor flashes in the
first line, indicating that the display is ready for
operation. All the incoming characters are displayed
in ASCII format on the terminal (exception:
CR,LF,FF,ESC,’#’). The prerequisite for this is a
working protocol frame or a deactivated protocol (see
pages 10 and 11).
Line breaks are automatic or can be executed by
means of the ‘LF’ character. If the last line is full, the
contents of the terminal scroll upward. The ‘FF’
character (page feed) deletes the terminal. The
character ‘#’ is used as an escape character and thus
cannot be displayed directly on the terminal. If the
character ‘#’ is to be output on the terminal, it must be
transmitted twice: ‘##’. The size of the terminal-
window can be set by command 'ESC TW'.
Terminal-Font 2: 8x16
Attention: Graphic commands are able to draw inside
terminal window. For example 'ESC DL' will delete terminal window, too.
USING THE SERIAL INTERFACE
The operating unit can be programmed by means of various integrated commands. Each command
begins with ESCAPE followed by one or two command letters and then parameters.
There are two ways to transmit commands:
1. ASCII mode
- The ESC character corresponds to the character ‘#’ (hex: $23, dec: 35).
- The command letters come directly after the ‘#’ character.
- The parameters are transmitted as plain text (several ASCII characters) followed by a separating
character (such as a comma ‘,’) - also after the last parameter e.g.: #GD0,0,479,271,
- Strings (text) are written directly without quotation marks and concluded with CR (hex: $0D) or LF
(hex: $0A).
2. Binär mode
- The escape character corresponds to the character ESC (hex: $1B, dec: 27).
- The command letters are transmitted directly.
- The coordinates xx and yy are transmitted as 16-bit binary values (first the LOW byte and then the
HIGH byte).
- All the other parameters are transmitted as 8-bit binary values (1 byte).
- Strings (text) are concluded with CR (hex: $0D) or LF (hex: $0A) or NUL (hex: $00).
No separating characters, such as spaces or commas, may be used in binary mode.
The commands require no final byte, such as a carriage return (apart from the string $00).

TOUCH PANEL
The Version EA eDIPTFT32-ATP is shipped with an analog, resistive touch panel. Up to 60 touch
areas (keys, switches, menus, bar graph inputs) can be defined simultaneously. The fields can be
definedwithpixelaccuracy. Thedisplaysupportsuser-friendlycommands. Whenthetouch“keys”are
touched, they can be automatically inverted and an external tone can sound (pin 16), indicating they
have been touched. The predefined return code of the “key” is transmitted via the interface, or an
internal touch macro with the number of the return code is started instead.

TOUICH ADJUSTMENT
The touch panel is perfectly adjusted and immediately ready for operation on delivery. As a result of
aging and wear, it may become necessary to readjust the touch panel:
1a. Send Command 'ESC A@' or
1b. Touch the touch panel at power-on and keep it depressed. After the message “touch adjustment
?” appears, release the touch panel. Touch the touch panel again within a second for at least a
second.
2. Follow the instructions for adjustment (press the 2 points upper left and lower right).
RESPONSE OF THE EA EDIPTFT32-A VIA SERIAL INTERFACE
The table below contains all response codes. Some response data will come automatically some
others on request. In addition to that with command 'ESC SB ...' user is able to transmit individual data
packages. All reponses are placed into the sendbuffer. With the smallprotocol command ’Request for

PRELOADED FONTS
As standard, there are 3 monospaced, 3 proportional character sets and 2 large digit fonts integrated.
The proportional character sets (which have a narrow “I” and a wide “W”, for example) look better and
take up less space on the screen. Each character can be placed with pixel accuracy, and its height
and width can be increased by a factor of 1 to 8. A text can be output left justified, right justified or
centered. Rotation in 90° steps is possible. Macro programming permits further fonts to be integrated.
All kinds of fonts can be converted from True-Type
Fonts by using using the LCD toolkit/
eDIPTFTcompiler (the USB Evaluation Board
EA 9777-2USB is required).

COMPILER OPTION "WinFont:"
It is possible to raster TrueType-Fonts in
different sizes witch can be used. A double-
click to the fontname within the KitEditor opens
the font selection box.
To simplify the use of fonts, there is the
possibilty of a edit box. If you output a string
with KitEditor (e.g. #ZL 5,5, "Hello"), you can
perform a double click on the string to open it.
Now you can select the desired characters. This is mainly recommended
using cyrillic, asian or symbol fonts.
In that way, the KitEditor automatically places the right ASCII-Code.
Alternativly you can use instead of the quotation mark curly brackets
(e.g. +ZL 5,5, {48656C6C6F}).
COMPILER OPTION "Font:"
Following font formats can be used:
- FXT: Textfont as used by eDIP240/320 and KIT series
- G16: internal eDIPTFT format (with this format it is possible to
user color fonts)
65,536 COLORS
EA eDIPTFT32-A is able to work with 65,536 colors for
true-color pictures/icons and animations. For an easy use
there exists a color palette with 32 entrys (16 colors are
predefined after PowerOn). This color palette can be

BORDERS, KEY STYLES AND BARGRAPH
The eDIP is shipped with 20 predefined border (no:1..20) for the
commands draw box frame and draw
touchkeys.There are also three
special borders in various colors for
using with bargraph commands
(no:101..107,
111..117
and
121..127). All of them can be used in
various sizes via coordinates. The
frames1..20aresplitinto3segments:
the outer frame, inner frame and
filling. Each segment will get an
individual colour for normal and for
selected state. This will give the user
theopportunity,whentouchingafield,theindividualpartofthekeywill
be inverted only.
FILL PATTERNS
A pattern type can be set as a parameter with various commands. In
this way, for example, rectangular areas and bar graphs can be filled
with different patterns. The eDIP is shipped with 20 predefined fill
patterns.
Define own pattern:
WiththeLCD-toolsitispossibletodefinenew pattern(=bitmapswith
exactly 8x8 dots).(Compileroption "Pattern:"). The foreground- and
backgound color can be set for monochrome pattern (as the 20
preloaded pattern) incl. transparency. It is also
possible to define full colored pattern.With the
LCD-tools some sample pattern has been
installed (see folder 'Pattern').

DEFINE OWN BORDER
With the LCD-tools it is possible to define new borders (Compileroption "Border:"). Each of these new
borderisabitmapwithexactly24x24dots(9segmentswith8x8dots:4xedge,4xmiddlepart,1xfilling).
Scaling for bigger touchkeys/
frames will be done by repetition of
these 8x8 dot segments. This
makes it necessary to keep the 8x8
size in every case. If 4-color
bitmapsareused(asthepreloaded
border 1..20) the color can be set
individually (the first color is always
transparent and is not used by the
eDIP). It is also possible to define
full colored border (as the
border25:

preloaded border for bargraphs
101...127).With the LCD-tools some sample border has
been installed (see folder 'Bitmaps\Color\Border').
ROTARY AND POINTER INSTRUMENTS
With the help of the LCD-Tools it is possible to include instruments (Compiler command:
Instrument: 4, <instrument.i16>). Performing a double click in the KitEditor on the
instrument file opens the instrument editor.
The instruments are supported by convinient commands (’ESC I..’). For example the instruments are
connectable to an analog input. In addition they are configurable by touch.

BUTTONS AS KEYS
Apart from the border types, which are infinitely scalable, it is also possible to use bitmaps as touch
keysortouchswitches(Compilerotion"Button:").AbuttonalwaysconsistsoftwoBitmapsofequalsize
(one bitmap to display the touch key in its normal state and another for when it is pressed). The active
area of the touch key automatically results from the size of the button bitmaps.
SWITCHES IN GROUPS (RADIO GROUPS)
Touch switches change their status from ON to OFF or vice versa each
timetheyaretouched. Severaltouchswitchescanbeincludedinagroup

CREATING INDIVIDUAL MACROS AND IMAGES
To create your own fonts, images, animations and macros you need the following:
- To connect the display to the PC, you need the EA 9777-2USB USB evaluation board, which is
available as an accessory, or a self-built adapter with a MAX232 level converter (see the application
example on page 5).
- ELECTRONIC ASSEMBLY LCD-Tools*), which contains a kiteditor, bitmapeditor, ediptftcompiler,
fonts, images, border, pattern and examples (for Windows PCs)
- A PC with an USB or serial COM interface
To define a sequence of commands as a macro, all the commands are written to a file on the PC (e.g.
DEMO.KMC). You specify which character sets are to be integrated and which command sequences
aretobeinwhichmacros. Ifthemacrosaredefinedusingthekiteditor, youstarttheeDIPTFTcompiler
using F5. This creates a file called DEMO.DF. If an EA 9777-2USB evaluation board is also connected
or the display is connected to the PC via a MAX232, this file is automatically burned in the display’s
data flash memory. You can send the created macrofile *.DF with any other system to the EA
eDIPTFT32-A. All programming commands are inside this file, so you only need to send the content
of the *.df file (via RS232, SPI or I2C with smallprotocol in packets) to the EA eDIPTFT32-A.
KIT-EDITOR HELP (ELECTRONIC ASSEMBLY LCD TOOLS)

IMAGES
Tosavetransfertimeviaserialinterface,itispossibletostoreupto256bitmapsá16pagesintointernal
dataflash (Compileroption "Picture:"). Following image file-formats can be used:
- BMP: Windows Bitmap with 1-, 4-, 8-, 16-, 24-, 32-BIT colordepth incl. RLE.
- GIF: Graphics Interchange Format incl. optionally transparency
- JPG: JPEG Compressed Images
- TGA: TARGA Images with 8-, 16-, 24-, 32-BIT colordepth incl. RLE and transparency.
- G16: internal eDIPTFT format, incl. RLE and transparency
All pictures are converted into internal G16 format with RLE encoding (saves memory). Too big
pictures are resized proportional (Compileroption "MaxSize:"). It is also possible to reduce the
colordepth (Compileroption "MaxColorDepth:"). One color can be defined as transparent
(Compileroption "MakeTransparent:“) The internal pictures can be used with the command "ESC U
I"viaserialinterfaceorfromamacro.Theforeground-andbackgoundcolorcanbesetformonochrome
pictures incl. transparency.
ANIMATIONS
It is possible to store up to 256 animations á 16 pages into internal dataflash. (Compileroption
"Animation:"). Following image file-formats can be used:
- GIF: animated GIF (only identically transparent areas, transparency can be switched off).
- G16: internal animated eDIPTFT format
- two or more single bitmaps (BMP, GIF, JPG, TGA, G16) e.g. two bitmaps for blinking
Note that max. 4 animations (animationprocesses) can run at the same time . The animations are
selfrunning pictures, but you can use the animations manually too. The foreground- and backgound
color can be set for monochrome animations.
PATTERN
Patterns are used to fill a box, a bargraph or to draw a line. It is possible to store up to 256 pattern á 16
pages into internal dataflash (Compileroption "Pattern:").
Each bitmap (BMP, GIF, JPG, TGA, G16) with a size of 8x8 dots can be imported as a pattern. The
foreground- and backgound color can be set for monochrome pattern incl. transparency.
BORDER / BARGRAPH
A border can be scaled and is used for rectangles, bargraphs and touch keys/switches. It is possible
to store up to 256 border á 16 pages into internal dataflash (Compileroption "Border:")
Each bitmap (BMP, GIF, JPG, TGA, G16) with a size of 24x24 dots can be imported as a border. The
transparency of GIF,TGA and G16 bitmaps is used by the EA eDIP. It is possible to change the colors
for 4-color borders, the first color ist always transparent and is not used by the EA eDIP. When used
for a touch key/switch a second border can be loaded witch will be used if the touch key/ switch is
pressed.
IMAGES AS TOUCHKEYS (BUTTONS)
It is possible to store up to 256 touchkeys/buttons á 16 pages into internal dataflash. (Compileroption
"Button:").
A button consists of one or two images with the same size (BMP, GIF, JPG, TGA, G16). The
transparency of GIF,TGA and G16 bitmaps is used by the EA eDIP and should be identical. The first
bitmap is used when the touch key/switch is released and the second bitmap is used if the touch key/
switch is pressed.

MACROS
Singleormultiplecommandsequencescanbegroupedtogetherinmacrosandstoredinthedataflash
memory. You can then start them by using the Run macro commands. There are different types of
macro (compiler directive marked in green letters):
Normal macro Macro:
These are started by means of an ‘ESC MN xx’ command via the serial interface or from another
macro. A series of macros occurring one after the other can be called cyclically (movie, hourglass,
multi-page help text). These automatic macros continue to be processed until either a command is
received via the interface or a touch macro with a corresponding return code is activated.
Touch macro TouchMacro:
Started when you touch/release a touch field (only in versions with a touch panel - TP) or issue an
‘ESC MT xx’ command.
Bit macro BitMacro:
will be started by a single line IN 1..8 (bit) will change or by command 'ESC MB xx'. Bit- Macro 1..8 are
good for falling edge and Bit Macro 9..16 are good for rising edge at input 1..8. It is possible to change
the assignment between Bitmacro and intput with command ‘ESC YD n1 n2 n3’ (see page 17).
Port macro PortMacro:
These are started when voltage (binary) is applied to IN 1..8 or by command 'ESC MP xx'.
Matrix macro MatrixMacro:
Matrix Macro 1..64: start when keypressed or by command 'ESC MX xx'. Matrix Macro 0: start after
release of key or by command. It is possible to change the assignment between keynumber and
Matrixmacro with command ‘ESC YX n1 n2 n3’ (see page 17).
Analogue macro AnalogMacro:
will start whenever voltage changes or limit exceeds or by command
'ESC MV xx'. See table at the right: It is possible to change the

Power-on-macro PowerOnMacro:
Started after power-on. You can switch off the cursor and define an opening screen, for example.
Reset-macro ResetMacro:
Started after an external reset (low level at pin 5).
Important: If a continuous loop is
programmed in a power-on, reset, watchdog
or brown-out macro, the display can no longer
be addressed. In this case, the execution of
the power-on macro must be suppressed.
You do this by wiring DPOM:
Watchdog-macro WatchdogMacro:
Started after a fault/error (e.g. failure).
Brown-out-macro BrownOutMacro:
Started after a voltage drop under 3.0V (typ.).
- PowerOff - connect pin 13 (DPOM) to GND
- PowerOn - open pin 13 (DPOM) again.

MACRO PAGES (MULTILINGUAL CAPABILITY)
There are 16 complete macro sets available as well as the internal images and fonts. By simply
switching the active macro page (ESC M K n1), for example, up to 16 different languages can thus be
supported.
If a macro/picture is defined in the kit editor, a page number can be specified in square brackets after
themacro/picturenumber.Ifamacro/imageisnotdefinedinthecurrentlysetpage[1]to[15],thismacro/
picture is automatically taken from page [0]. Thus, not all macros and images have to be stored
separately for each language when they are identical in each language.
