4.2.2 General Purpose Input/Output

The iCOMPEL can respond to changes in voltages generated by a GPIO device such as a motion sensor or a pressure
mat. The iCOMPEL receives those inputs through its RS-232 port. It can also send output signals. For more details see
the RS-232 Technical Reference
Control Line Inputs:
The iCOMPEL RS-232 port has four input lines that can receive binary events such as contact closure or signals from other
devices. The available lines are:
Clear To Send (CTS).
Data Carrier Detect (DCD).
Data Set Ready (DSR).
Ring Indicator (RI).
The lines do not affect the operation of the RS-232 Send and Receive strings.
Include an RS-232 Input Items in a playlist and configure it to issue an Advance To or Change Layout command. Use
those commands to change the media played by the iCOMPEL. This is triggered when the iCOMPEL detects a line
transition generated by a user action.
Control Line Outputs:
The iCOMPEL can control the output state of the RS-232 DTR and RTS lines. Create RS-232 Output Items to change one
or both RS-232 outputs and optionally transmit a string of characters. Give the RS-232 Output Items unique names to
clarify their purpose in the iCOMPEL configuration.

4.2.3 Touch Screens

The iCOMPEL includes support for touch screen input from users. These features allow you to configure the iCOMPEL to
respond to those user inputs (for example, by executing Advance To or Change Layout commands). Connect an overlay
touch-screen panel to the iCOMPEL through its USB port.
You can configure the response at one or both of these levels:
Touch screen physical interface – The iCOMPEL supports USB touch-screen overlays that report absolute X/Y
coordinates and key up and key down events. There is no support for a mouse-like device that sends relative movements
since this requires an on-screen cursor.
Touch screen calibration – On the menu bar, click Setup and select Player > Interactivity. Click the Touch tab and
click the
