Serial Input Event

Open

The Serial Input event triggers when the BrightSign player receives input from a device connected to a serial port.

• Specify port: Enter the port number of the input device. Most standard RS-232 serial devices enumerate on port 0. If you are connecting a USB-serial device, it will enumerate on port 2. To configure the serial port, navigate to Presentation Settings > Interactive > Connectors.

• Specify serial input: Enter the serial input string that will trigger the event. You can also use the <*> wildcard to match some or all of the serial input (i.e. entering "<*>" in this field will match any input, while entering "mycommand_<*>" will match any input message that begins with "mycommand_").

• Assign input to variable?: Check this box to assign the content of the serial input to a User Variable.

  • Input specifies variable: The serial input string will dynamically specify which User Variable to modify. The serial input string must be sent in the form of "<variable name> : <variable value>".

  • Specify fixed variable: The serial input string will modify a fixed User Variable. Use the dropdown list to choose which User Variable the serial input will modify. The serial input string must be sent in the form of "<variable value>".

• Assign wildcard to variable?: Check this box to specify the value of a User Variable using the <*> wildcard. Select the User Variable to modify using the dropdown menu to the right. The Specify serial input field must contain the <*> wildcard, either by itself or with additional text (e.g. "message_<*>").
