y PCI-1409 and IMAQ function) at accurately (hardware) specified time intervals and then 2)read these values from the file, again at an accurately known rate (real time) in order to synchronise with the video being played through a PCI-1409 frame grabber ?The requirement here is to:
1) log data to file (one serial port RS232 input and 3 or 4 analogue input using a PCI-6024E. A header will also be produced and the file given a corresponding name)
The trigger to start the data logging will be given by a drastic change in scene and this will be provided by IMAQ functionality from a PCI-1409 frame grabber.
2) During the datalogging a video sequence is s
imultaneously recorded on digital 8 format
3) Then it is necessary to recreate this DAQ situation by playing the video through a PCI-1409 IMAQ card and
simulataneously read the data from the spreadsheet file at a real time rate, therefore not allowing an out-of-synch situation. the same 'drastic scene change' will be used as the trigger.
A RTSI cable between the 2 boards exists, but i am struggling to accurately timebase all my measurements and synchronise the readback.
I am using win 2000 pro and LABVIEW 6.1
Any ideas ?
