EA KIT240-7
GENERAL
The EA KIT240 graphics kit is a fully assembled control and operating unit with a variety of integrated
functions. The display has very compact dimensions and offers excellent super-twist contrast, which
means the unit can be put into operation immediately. It is controlled via the standard RS-232 or
RS-422 interface. In addition to complete graphics routines for display output, the graphics kit also
contains a wide variety of fonts. Graphics command similar to those used in high-level programming
languages are used for programming. There is thus no longer any need for the time-consuming
programming of character sets and graphics routines. The ease of use offered by macros and input
via touch panel make it a real power display.

HARDWARE
The graphics kit is designed for an operating voltage of +5V. A supply voltage of 9..35V is also possible.
Serial asynchronous data transfer is carried out in RS-232 or RS-422 format. The transmission format
is set permanently to 8 data bits, 1 stop bits, and no parity. A transimssion rate of between 1200 and
115,200 baud can be selected by means of DIP switches. RTS and CTS handshake lines are available.
Data format:
TOUCH PANEL
The EA KIT240-7CTP and -7LEDTP versions are equipped with an integrated touch panel. You can
make entries and choose menu 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 or grouping of several fields is handled by the integrated software.
SOFTWARE
The graphic kits are programmed by means of commands such as Draw a rectangle from (0,0) to
(64,15) . No additional software or drivers are required. Strings can be placed with pixel accuracy.
Text and graphics can be combined at any time. Up to 16 different character sets can be used. Thus,
when the 8-times zoom is used with character set 16x8, the words and numbers fill the screen.
ACCESSORIES
Front panel for mounting
A front panel made of anodized aluminum is available as an accessory. This allows the graphics kit
to be mounted without any screws visible. Installing it is child's play. The EA 0FP240-7 front panel is
available in black (SW) and blue (BL).
Floppy disk for creating macros
A floppy disk (EA DISK240) is required for macro programming
entered in a text file into a code that can be read by the graphics kit, and programs them into the
EEPROM.
Cable for PC
To enable simple connection to PCs (macro programming), we provide a 1.5m cable and a 9-pin SUB-D
female connector (EA KV24-9B). Simply insert it into COM 1 or COM 2 and get started. Note: The cable
is not suitable for the RS-422 version (EA OPT-RS4224).
