Instead of the capacitive buttons used with the CWT 2110 and 2115 models the CWT 2120 touch screen can show simulated soft buttons and even key arrays such as a simulated keyboard. It is possible to use any number of buttons, and the buttons can be placed anywhere within the display area.
Figure 10. CWT 2120 has a colour TFT 640 x 480 pixels display with touch screen functions.
The function, position, size, etc. of each button are defined in the UI.xaml file.
