Hardware device connections at BIAC-5 3T (MR750) scanner

Darwin computer

Darwin is our primary stimulus presentation computer. It is usually connected to the monitor on the left.
Darwin has the following peripheral hardware connected:

  • Keyboard and mouse hard-wired connections
  • Audio and video output connected to video switch (CPU 3)
  • GE scanner cardiac/respiratory connected to MCC
  • Current Design 8-button serial response device (USB keyboard device, default mode)
    • button box mode: “HHSC-2×4-C” response box
    • button mode : “HID NAR NO 5” (003)
      • must check this mode if power is cycled to the interface
      • “NO 5” does not send the trigger pulse as a 5
  • Current Design 2 axis, 2 button joystick
    • autoconfigure
    • HID Joystick
    • USB - Tethyx
    • after use switch back to button box with above settings
  • Current Design Trackball 2 ( shared between 2 scanners )
    • autoconfigure
    • HID HHSC-TRK-2 ( track 2 and comp seem to do the exact same thing )
    • roll ball around to calibrate
    • after use switch back to button box with above settings
  • Measurement Computing Analog/Digital data acquisition device (USB-1208FS, dev=0, 8 a/d chans)
    • to reset AD device disconnect USB cable.
  • E-Prime dongle connected to USB port
  • Biopac belt respiratory signal connected as MeasComp analog input (ch 0, w/ 1Kohm resistor), biopac analog ch4
  • Biopac cardiac signal connected as MeasComp analog input (pulse ch3, OxSat ch4), biopac analog ( o2 ch3, pulse wave ch7, pulse rate ch11)
  • BioPac GSR signal connected as MeasComp analog input (ch 1)
  • BioPac EGG signal connected as MeasComp analog input (ch 2)
  • Measurement Computing Box, DigPort-A0 Output to Analog Ch6 In, to BioPac Analog 8 input
  • Measurement Computing Box, DigPort-A1 Output to Analog Ch7 In
  • Scanner trigger cable connected MeasComp analog (ch 5) and digital (B0), biopac analog CH 9
  • Scanner trigger is also connected to the MCC counter pin (CTR), this would show up as a number increase NOT a positive pulse
  • Scanner trigger is also connected to button box interface
    • “HID NAR 12345” setting on fORP allows the trigger to come through as a 5
