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)
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
biopac manual
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)
