Control-Line Inputs:
The player RS-232 interface 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).
l
Data Carrier Detect (DCD).
l
Data Set Ready (DSR).
l
Ring Indicator (RI).
l
The lines do not affect the operation of the RS-232 Send and Receive strings.
Include an RS-232 input item 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 player. This is triggered when the player detects a line transition generated by a
user action.
Control Line Outputs:
The player 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.
4.2.3 Touch Screens
The player includes support for touch screen input from users. These features allow you to configure the player to respond to
those user inputs (for example, by executing Advance To or Change Layout commands). Connect an overlay touch-screen
panel to the player through its USB port.
4.2.4 Click On Touch
You can configure the player to play an audio file when someone touches an interactive screen.
To play an audio file, click the layout's Interaction tab and enable Click on Touch. The player does not play a sound when
the setting is No Click on Touch.
Specify these items:
Volume – Express volume as a percentage of the Master Volume level. (You can specify the Master Volume level on the
l
Audio page in the Setup menu.) If this entry is blank, the player uses 75% of the Master Volume level.
Actions – Check the audio file's Use sound button. If necessary, navigate to the location of the file using the folder
l
display.
4.3 Using the RS-232 Interface Port
If you require the player to control equipment through an RS-232 interface, use its built-in RS-232 port or the USB to RS-232
adapter, whichever is appropriate for the player model.
Considerations for sending RS-232 strings at specific events or playlist positions:
Define the strings by expressing their byte values as separated hexadecimal pairs (for example, 3A 3B 3C 0D 0A).
l
Create the strings in accordance with the needs of the attached device.
