TOUCH PANEL
The versions -7xxTP are supplied with an analog resistive touch panel. Up to 60 touch regions
(buttons, switches, menus, bar graph entries), can be defined simultaneously. The fields can be
defined to single-pixel accuracy. The display supports representation using easy-to-use commands
(see page 15). When the touch “keys” are touched, they can be automatically inverted and an external
buzzer (pin 16) can sound, indicating they have been touched. The defined return code of the “key”
is transmitted via the serial interface, or an internal touch macro with the number of the return code is
started (see page 18, Macro programming).
TOUCH PANEL 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.
Adjustment procedure:
1. Touch the touch panel at power-on and keep touching it. After the message “touch adjustment ?”
2. Touch the touch panel again within a second for at least a second.
3. Follow the instructions for adjustment (press the 2 points upper left and lower right).
FRAMES AND KEY FORMS
A frame type can be set by using the Draw frame or Draw frame box command or by
drawing touch keys. 18 frame types are available (0= do not draw a frame).
BITMAPS AS KEYS
In addition to the frame types, which can be scaled to any size, you also have the option
of using any bitmap images (in each case, a pair showing the not pressed and pressed
statuses) as touch keys or switches.

SWITCHES IN GROUPS (RADIO GROUP)
Touch switches change their status from ON to OFF and vice versa each time they are touched. A
number of touch switches can be grouped together (command: ‘ESC A R nr’). If a touch switch in an
‘nr’ group is now switched on, all other buttons in this group are automatically switched off. This means
that one button is only ever on at a time.
