1. About
--------
-In EEG/ ERP studies it is common to send triggers to mark the time of significant events (e.g., the onset of a trial, presentation of a particular stimulus, etc.). Triggers are typically bytes that are sent via the parallel port to the EEG apparatus. This can be done with the parallel port trigger plugin which works in Linux and Windows. For Windows the `DLPortIO.dll` driver is used to access the parallel port.
+In EEG/ERP studies it is common to send triggers to mark the timestamp for significant events (e.g., the onset of a trial, presentation of a particular stimulus, etc.). Triggers are typically bytes that are sent via the parallel port to data acquisition systems.
-The plugin has three input boxes:
-- Value ranges between 0-255
-- Duration in ms
-- Parallel port adress has to be specified manually (Windows only)
+The plug-in has three options:
+- *Value* is a positive integer between 0-255 and specifies the trigger byte
+- *Duration* (ms) is a positive integer, 'keypress', or 'mouseclick', to wait respectively for a specified interval in milliseconds, until a key has been pressed, or until a mouse button has been clicked. It specifies the time the trigger is active.
+- *Port adress (Windows only)* is the hexadecimal value of the parallel port in Windows. This setting is ignored in Linux.
+

+Linux and Windows are supported (possible also OSX, not tested). For Windows the `DLPortIO.dll` driver is used to access the parallel port. Install options are listed below.
Installation instructions:
The Parallel Port Trigger plugin allows you to send signals out - a parallel port. This allows you to, for example, send - synchronization TTL pulses to an EEG amplifier during your experiment..
-The following options are available:
-Value can be a - number between 0 and 255
-Duration should be a - positive integer value, 'keypress', or 'mouseclick', to wait - respectively for a specified interval in milliseconds, until a key - has been pressed, or until a mouse button has been clicked.
-Port Adress (Windows only) - should be the the value of the parallel port adress in Windows.
