Lifelines trackit EEG recording with LabVIEW

Question

Hi, I am trying to control a lifelines trackit EEG (www.llines.com) recorder using LabVIEW via serial communication (DB9). Does anyone has any experiences connecting this device with labview? I've done several communication via serial communication with labview before but not as tough and difficult as the current task. I am not able to understand the device (trackit) command in order for me to apply the Basic Serial Read and Write VI. Please advice. I have the Lifelines trackit recorder Interface specification in softcopy as reference but do not know how to attach here. Please let me know if you guys need the  copy as reference. TQVM
Host Transmit Write Data and Write Command
[SOP] <AddrHi> <AddrLo> [Chr(W)] <ParamBlock> <Index> [EOP]
Or:
[SOP] <AddrHi> <AddrLo> [Chr(W)] <ParamBlock> <Index> [Data]# [EOP]
Or:
[SOP] <AddrHi> <AddrLo> [Chr(W)] <ParamBlock> <Index> <Data># [EOP]
Or:
[SOP] <AddrHi> <AddrLo> [Chr(W)] <ParamBlock> <Index> {Data}# [EOP]

Answer 1

Is there a demo program from the manufacturer that works?? you can use portmon or NI spy to capture the serial datastream and reverse engineer the labview code. Sometimes ya have to think like a hacker.
