EXTERNAL KEYBOARD (EA KIT120-5LED ONLY)
A keyboard (anything from individual keys to a 5x2 matrix
keyboard) can be connected at the plug-in connection J4. The
connected keys are debounced by means of software. Please
note that it is only possible to connect an external keyboard to the
EA KIT120-5LED version without an integrated touch panel and
without additional options (OPT-OPTO10= or OPT-9/36V).
Each key is switched between an output and an input. The inputs
have a 50kΩ pullup. Up to 5 keys can be connected at each
output.
follows: (output -1) * 5 + input (output: the number 1 or 2, input: between 1 and 5).
Note: If the handshake line (e.g. CTS) does not permit transmission, keystrokes can be lost.
TOUCH PANEL
The EA KIT120-5LEDTP version is equipped with an integrated touch panel with 10 fields. The graphics
unit offers convenient commands supporting this touch panel. It is possible, for example, to group a
number of touch fields to form a single large key and then draw and label the key. You can also assign
a return code (1..255) to the key you have defined. If a return code of 0 is assigned, the key is disabled
and has no effect when pressed.
When the touch keys are touched, they can be automatically inverted and a tone can sound, indicating
they have been touched. At the same time, the internal touch macro with the number of the return code
is started or, if no touch macro is defined, the return code of the key is transmitted via the serial interface.
Example:
Definition of a key from field 4 to 10 with the return code 65=´A´ and the text „STOP“. Note: Before
individual keys are defined, all fields should be disabled by means of „ESC T R“.

Transmitting the keystrokes
At each keystroke, the associated key
number (1..10) is transmitted. 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 touch macro no. 0. The
automatic keyboard scan can be deactivated
by means of the „ESC T A 0“ command.
The key number can be determined as
