QTERM-G56 Terminal Terminal Components
Qlarity-Based Terminal Hardware 59
4.3.2 Touch Screen
The QTERM-G56 touch screen provides user input through any number of touch keys located
on the display. Touch keys can be defined in your user applications at any location on the dis-
play and may be any size. Most visible objects in the Qlarity Object libraries are inherently
touch-sensitive. The touch screen functionality can also be enabled or disabled in software
(either in the user application or via the Power On Setup utility).
4.3.3 Keypad
User input also occurs through a rugged 24-key or 40-key membrane keypad with steel snap
domes. The top row of keys are commonly used as soft keys to navigate through a set of
changing menus at the bottom of the display. The standard keypad comes with four or five
LEDs under the soft keys that can be used as status or alarm indicators. Power and shift but-
tons with LEDs are included on both keypad configurations. The power button enables and
disables the internal power supply for true shutdown.
The standard 40-key keypad legend allows for function / soft keys, eight-way directional con-
trol and numeric entry in the unshifted mode and alphanumeric data entry in the shifted mode.
Keys can perform alternate functions when the shift key is enabled. The power and shift func-
tions can be enabled or disabled in software.
The keypad legend can be customized with your logo/name and custom keys.
4.3.4 Speaker
A speaker is built into the QTERM-G56 terminal and faces to the back of the unit. Audio can
be linked to events or actions (e.g., key press, timer, etc.). Pitch and duration of a note are con-
trolled by API functions called from the user application. Refer to the “Controlling the
Speaker” section in the Qlarity-based Terminal Programmer’s Reference Manual. Volume
control is also accessible via software.
