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.
The displays are ready for operation immediately with an operating voltage of 5V. 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-consuming
programming 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 of +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.
ANALOG 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: BLUE, WHITE, AMBER
All displays are equipped with modern, energy-saving LED illumination. Brightness can be varied
0~100% by command. While the black&white display (J-LW) and the amber one (J-LA) can also be
read with the illumination switched off entirely, the blue-white display (B-LW) needs at least minimal
illumination if it is to be read.
We recommend the black&white or amber version for use in direct sunlight. In all other cases we
recommend the very high-contrast blue-white version.
In 24-hour operation, the illumination of the J-LW and B-LW types should be dimmed or switched off
as often as possible to increase their lifetime. The amber version (J-LA) is also suitable for continuous
use at 100% illumination (MTBF 100,000 hours).
SOFTWARE
This display is programmed by means of commands, such as
Draw a rectangle from (0,0) to (64,15).
No additional software or drivers are required. Strings and images can be placed with
pixel accuracy.
Flashing attributes can be assigned as often as you like. Text and graphics can be combined at any
time. Up to 32 different character sets can be used. 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
PROGRAMMER FOR INTERNAL DATA FLASH MEMORY
The display is shipped fully programmed and with all fonts. The additional programmer 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 USB programmer EA 9778-1USB, which is available as an accessory, will
burn the data/images you have created into the on-board data flash memory (80 kB) permanently.
The programmer runs under Windows and is connected to the PC’s USB interface. It is shipped with
an interface cable and the installation software.

OUTPUTS
The EA eDIP320 offers up to 8 outputs, which can be used to control LEDs, for example. The
configuration pins used depend on the interface selected (RS232, SPI or I²C). The configuration pins
(open drain with internal pullup) are then evaluated as 1=HIGH level.
Each output can be controlled by means of the ‘ESC YW n1 n2’ command. Current can only flow
when the level is at L (open drain with internal pullup). Each output can supply a maximum of 10 mA.
It is thus possible to connect an LED to an output directly. Higher currents can be connected by using
an external transistor.

RS-232 INTERFACE
If the display is wired as shown below, the
RS-232 interface is selected. The pin
assignment is specified in the table on the
right.
The RxD and TxD lines lead 5V (CMOS level)
to a microcontroller, for example, for direct
connection.
If “genuine” RS-232 levels are required (e.g.
for connection to a PC), an external level
converter (e.g. MAX232) is required.

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.
BAUD RATES
The baud rate is set by means of pins 6, 7 and 8 (baud 0 to 2). The
data format is set permanently to 8 data bits, 1 stop bit, no parity.
RTS/CTS handshake lines are not required. The required control is
taken over by the integrated software protocol (see pages 8 and 9).

RS-485 INTERFACE
With an external converter (e.g. SN75176), the EA eDIP320 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 eDIP320
displays can be operated on a single RS-485 bus by setting addresses.
We recommend the EA 9778-1RS485 board for development.
Addressing:
- Up to eight hardware addresses (0 to 7) can be set by means of pins ADR0 to 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 deselected after power-on.
- Up to 246 fur ther software
addresses can be set by means
of the ‘#KA adr’ command in the
power-on macro (set the eDIP
externally to the address 0).
