-The video **AND** audio connections between the computers, dvd player, monitors, 3D LCD at each scanner pass through a software-controllable video switching box. The box is located in the rack that contains the 2 stimulus control PC's in the scanner equipment room.+Web Gui connection from Tech iMac at each scanner:

 +The video **AND** audio connections between the input ( computers, DVDetc ) and output ( monitors, projector, TV, headphones ) at each scanner pass through a software-controllable video switching box. The box is located in the rack that contains the 2 stimulus control PC's in the scanner equipment room. 
 + 
 +The video switching box only connects the audio/video signals. The keyboard and mouse devices on the console desk are connected directly to their respective computers and cannot be changed. This means you will probably find it hard to work if you connect monitor 1 to CPU 2 (or vice-versa) because the keyboards and mice will be linked to the wrong screens. 
 + 
 +The monitors contain integrated speakers and there is an HDMI audio extraction device connected to the subject's headphones as input.  This means that the audio signal to the subject is just another connection controlled by the switching software and the audio toggle switch no longer exists.  If you send INPUT1 to OUTPUTA, both audio and video from the stimulus presentation computer are sent.  So send audio/sound from the primary stimulus presentation computer to the console room and the subject, send INPUT1 to Left Screen, Projector and Headphones.

 + 
 +Currently the only ways to control the video switcher are:  
 +  * through a web GUI from the iMac ( connect to 10.0.1.229 at both scanners ) 
 +  * the small blackbird remote ( press the output you want to change, THEN the input you want to send ) 
 +  * the buttons on the switcher itself 
 + 
 + 
 +To control the switcher from the web interface: 
 +  * open [[http://10.0.1.229|http://10.0.1.229]] 
 +  * Click "Status" to show existing connections 
 +  * Go to "Matrix" to get to the switching interface 
 +  * each Output and their current Input will be shown 
 +  * hover over the IN# to change which input will be sent 
 +  * select the appropriate IN# to go to the output destination you are changing

-Currently at BIAC6 the video switching box only connects the audio/video signals. The keyboard and mouse devices on the console desk are connected directly to their respective computers and cannot be changed. This means you will probably find it hard to work if you connect monitor 1 to CPU 2 (or vice-versa) because the keyboards and mice will be linked to the wrong screens. 
  
-The monitors contain integrated speakers and there is an HDMI audio extraction device connected to the subject's headphones as input.  This means that the audio signal to the subject is just another connection controlled by the switching software and the audio toggle switch no longer exists.  If you send CPU1 to Screen1, both audio and video from the stimulus presentation computer are sent.  So send audio/sound from the primary stimulus presentation computer to the console room and the subject, send CPU1 Primary to Left Screen, Projector and Headphones.
