CCN is currently outfit with three MR safe response devices: 2 Button Box, 4 Button Box, and a Track Ball
CCN is also equipped with a USB 4 button practice device for use in the testing room outside of the scanner
- This device is NOT MR safe and should not enter the scanner room at any time

Setup

Device Connection

The three response devices are located in a drawer inside the scanner room labeled "Button Boxes"
Take one of the devices and remove the small rubber cap located on the connector
Remove the top optical bundle from the wall, and remove the rubber cab from the bundle connector
Gently find the correct orientation for the two connectors to interlock
- Once the correct orientation is found, connect the button box to the fiber bundle
Follow the instruction sheet attached to the desk above the silver button box interface in order to select the correct device and settings
- Trackball should be set to HHSC-TRK2
Once settings have been selected, please make sure your subject tests the buttons out before continuing

Please make sure the USB Cable has been plugged into the correct device!

Check to make sure the bottom row of lights on the button box interface light up when the corresponding buttons are pressed
- Left most light corresponds to the left most button (2BB) or the top button (4BB)
- If all the lights are flashing then the problem is most likely an issue with the connection to your computer
Check that the USB indicator on the button box interface is static (not blinking)
- A blinking USB status means the button box interface isn't registering that it's connected to a laptop/computer
If the USB status light is static (not blinking), open up a text document (word, pages, txt edit) and ask your participant to press the buttons; responses should be collected
If it works for a txt file but not your stimulus presentation program, keep the USB plugged in and restart your program (Matlab, PsychoPy etc.)
- Often what happens is these programs are started before the USB is connected, which doesn't allow the program to register the external device
