====== Prisma SSR EyeLink ======

  * The EyeLink Tray Mounted Camera needs to be placed before the study. 
  * We need to use the "fancy" first-surfaced mirror on the head coil.
    * This mirror needs extra care. It will scratch and smudge easily. It is difficult to clean.

Both of these are stored in the Prisma one scan room closet.

== EyeLink SetUp - Prisma 2 ==  

  - Ensure blue Ethernet coord is connected from the EyeLink Host PC to "EPrime"  Task computer
  - Ensure EyeLink Host PC is turned on
  - Ensure monitor and keyboard are switched to show the EyeLink computer (option #2)
  - Open the ''Manually_Set_IP.txt'' file on the task pc desktop (for  IP address reference later)
  - Adjust Windows IP address settings
     - Click on the **control panel**
     - click **View network status and task** under  //Network and Internet// section
     - click **change adapter** on the left sidebar
     - right-click on **local area connection** and select **Properties**
     - enter the same ''luna'' creds used for login
     - select **Internet Protocol 4** from the connection items
     - copy and paste address from the readme (both) <code>
100.1.1.2  -- is ip address

== Setup Camera display ==

  - click the **control** program form the desktop (blue eye icon)
  - switch the projector display switch to "task computer" if not already there
  - enter an ID
  - push **enter** once the screen has flash to gray to display the eye camera feed on the projector
  - push the **right arrow key** to show the full feed instead of just the eye
  - confirm camera is in focus and thresholds are reasonable
    - if pupil thresholding cannot be established with value above 65, the IR is likely not hitting the eye.

== Clean up ==
  - **RESET THE IP ADDRESS BACK TO UPMC**
    - follow the same control panel -> network properties -> adapter settings  as above but use <code>10.48.88.???</code>
  - remove the ethernet coord from the task computer (back to disconnected like before) 
  - Gentle reminder to switch back eyetracking monitor and keyboard are switched back to show original screen (option #1)
  - save the (hopefully) amazing ET data then LogOff of Luna on EPrime
