 The '5' key is used for a scanner trigger code, but this option is not connected at BIAC because anytime the scanner is acquiring images the button box acts as though you are repeatedly pressing the '5' key on the keyboard, which can be very annoying.  We have other input devices connected to the scanner trigger pulse.
-The 8-button box behaves like a keyboard. If the number keys on the computer keyboard work, the 8-button box should also work ( with one caveat as of **4/2011** ):

-MATLAB presentation software ( PsychToolBox,Cogent ) requires the button box to be in a specific mode which does not auto release.  This means that if a button is pressed and held down, then there will be streaming responses from the button box.  The default mode is to auto release, meaning 1 press sends 1 response regardless of how long you hold the button.

+**Default Setting ( 003 ):**
   * button box mode: “HHSC-2×4-C” response box
-  * button mode: “HID KEY 12345”

-If PTB-3 or Cogent are run in mode 001, buttons will still be recognized, however you will not receive all of your responses.  If changes are necessary for your experiment, please verify the setting with the MR-Techs prior to starting your functional scanning.
