Hardware device connections at BIAC-6 3T (MR750) scanner

BIAC6 3T -- Mach computer

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

  • Keyboard and mouse hard-wired connections
  • First video output connected to video switch (CPU 1)
  • Second monitor video output connected to video switch (CPU 2)
  • Stereo sound output to audio switch boxes
  • Current Design 8-button serial response device (USB)
    • button box mode: “HHSC-2×4-C” response box
    • button mode : “HID NAR 12345” (003)
      • must check this mode if power is cycled to the interface
  • MagConcepts Joystick (USB Gaming device)
  • E-Prime SR box (no button box, just scanner trigger) (COM1: 19200 baud, 8 bits, no parity)
  • Video switch serial cable on COM2
  • Measurement Computing Analog/Digital data acquisition device (USB-1208FS, dev=0, 8 a/d chans)
  • Serial cable to Donders on COM3 (e.g. ViewPoint eyetracker or Acknowledge)
  • E-Prime dongle (USB)
  • Scanner trigger cable connected as input to E-Prime SR box (code=16), and MeasComp analog (ADC3)
  • BioPac Respiratory belt signal connected as MeasComp analog input 0 (ADC0), biopac analog ch4
  • BioPac Cardiac signal connected as MeasComp analog input 1 (ADC1), biopac analog ( pulse wave ch6 )
  • BioPac GSR signal connected as MeasComp analog input 2 (ADC2), biopack analog ch1
  • Scanner trigger signal connected as MeasComp analog input 3 (ADC3)
  • Scanner trigger is also connected to the MCC counter pin (CTR), this would show up as a number increase NOT a positive pulse

BIAC6 3T -- Donders computer

Donders is our accesory computer. It is usually connected to the monitor on the right.
Donders has the following peripheral hardware connected:
