Analog Recorder†
Computer: MacPro(Quad-Core Intel Xenon 2.8GHz)
OS:MacOSX(10.6.5)
Environment: LabView2009(Developer)
National Instruments PCI-X board: PCIe-6259
32 ch NRSE Setting(16bit)
Channels: Acq,Cardio,Resp,4th,5th,...,32th
| ch | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
| AcqTrig | Cardio | Respir | EyePosX | EyePosY | EyeSize | Response1 | Response2 | |

100Hz recording
Acquisition trigger data has 1kHz resolution
Car2 format†
base: big endian 2byte integer data
{[Acq1][Card1][Resp1][SigA1][SigB1][SigC1]...[Sig$1]}
{[Acq2][Card2][Resp2][SigA2][SigB2][SigC2]...[Sig$2]}
...
...
{[AcqN][CardN][RespN][SigAN][SigBN][SigCN]...[Sig$N]}
Card1~N,Resp1~N,Sig(A~$)(1~N): 2byte signed integer
Acq1~N: [cbbbbbtt tttttttt] 2byte bit sequence
c(1bit): 1 for checking car2 data
bbbbb(5bits): [The integer plus 1] indicates the number of channels(1~32)
tt tttttttt(10bits): Acquisition trigger statement at each timing every 1 msec(above threshold[2.5V] or not)
The lowest bit corresponds to the earliest timing.
The following command should support car2 data
car_anlz(1.3),car2txt(1.1.1),txt2car2(1.0.1),ext_analyzer(1.0.4b),peak(1.15c)
Old Analog Recorder†

Car1 format†
base: big endian base 2-byte data(12 bit data is stored in 16 bit box)
[Resp1][Card1][Resp2][Card2][Resp3][Card3]...[Resp_N][Card_N]
Resp_1~N [AAAA NNNN NNNN NNNN]
(int)AAAA is the timing information of acquisition trigger onset(0[No onset],1~10)~ (12bit data)[NNNN NNNN NNNN]~
Card_1~N [AAAA NNNN NNNN NNNN]
(int)AAAA is empty("0000")~
(12bit data)[NNNN NNNN NNNN]~
Data conversion :
