Hardware device connections at BIAC-5 3T (MR750) scanner
BIAC5 3T -- 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, video, and mouse connected to KVM video switch (CPU 1)
Second monitor video output connected to KVM switch (CPU 2)
Stereo sound output to audio switch boxes (CPU1 - switch 1)
NeuroScan 4-button response box via E-Prime SRbox (COM1: 19200 baud, 8 bits, no parity)
GE scanner cardiac/respiratory cable (COM4)
Serial cable to Kulpe computer (COM3: 56K baud, 8 bits)
Serial cable to KVM video switch (COM2)
Current Design 8-button serial response device (USB keyboard device, default mode)
MagConcepts Joystick (USB Gaming device)
Measurement Computing Analog/Digital data acquisition device (USB-1208FS, dev=0, 8 a/d chans)
E-Prime dongle connected to USB port
Scanner trigger cable connected via SRbox (code=16), and MeasComp analog (ch 5) and digital (B0)
Scanner trigger is also connected to the MCC counter pin (CTR), this would show up as a number increase NOT a positive pulse
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
BIAC5 3T -- Kulpe computer
Kulpe is our accesory computer. It is usually connected to the monitor on the right.
Kulpe has the following peripheral hardware connected:
Keyboard, video, and mouse connected to KVM video switch (CPU 3)
BioPac communication (RJ45) cable
Serial cable to Darwin computer (COM1)
BIAC5 3T -- Other devices
DVD player, video output connected to KVM 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)
