Hardware device connections at BIAC-6 3T (New 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 Cardiac signal connected as MeasComp analog input 1 (ADC1), biopac analog ( o2 ch2, pulse wave ch6, pulse rate ch10 )
  • 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
  • Measurement Computing Box, DigPort-A0 Output to BioPac Analog 8 input
  • BioPac STM100c: MCC DigPort-A0 output to BioPac digital i/o ch15

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:

  • Keyboard and mouse hard-wired
  • Video output connected to video switch (CPU 3)
  • Stereo sound output to audio switch boxes
  • Serial cable to Mach (COM1)
  • Scanner trigger cable connected as input to parallel port
  • BioPac communication (RJ45?) cable
  • Falcon video capture card (internal board)
  • Mag Concepts eyetracker camera input (NTSC) to video capture card
  • OptoAcoustics digital microphone (USB)

BIAC6 3T -- Other devices

  • DVD player, video output connected to video switch (CPU 5)
  • DVD player, sound connected to Audio switch (DVD - switch 3)
  • Stereo sound jack for I-pod, MP3, etc connected to Audio switch (Aux - switch 4)

Video Switch Connections

Source Devices

  • CPU1 = Primary Display Computer (Mach), primary video output
  • CPU2 = Primary Display Computer (Mach), secondary video output
  • CPU3 = Secondary/Eyetracker Computer (Donders)
  • CPU4 = Not connected
  • CPU5 = DVD player
  • CPU6 = Not connected
  • CPU7 = Not connected
  • CPU8 = Not connected

Output Devices

  • OUT1 = Left Monitor
  • OUT2 = Middle Monitor
  • OUT3 = Right Monitor
  • OUT4 = Projector
  • OUT5 = TV
  • OUT6 = Not connected
  • OUT7 = Not connected
  • OUT8 = Not connected

Default Configuration "Stimulus to Subject"

Note: If you double-click the “Reset Video Switch” icon on the desktop, you will get the following configuration:

Source Output Labels
Mach 1 Left Monitor CPU1 → OUT1
Mach 2 Middle MonitorCPU2 → OUT2
DondersRight Monitor CPU3 → OUT3
Mach 1 Projector CPU1 → OUT4
DVD TV CPU5 → OUT5
Mach 1 No device CPU1 → OUT6
Mach 1 No device CPU1 → OUT7
Mach 1 No device CPU1 → OUT8
