Dear Sir,
i have NI
PCI 6255 80 channel data acquisition card and i am acquiring data of 80
channels at the sampling frequency of 4KHz per channel.
and one
chunk of acquired data is 1024*80 samples, mean 1024 samples for every channel.
I am
sending this acquired data to another PC say PC A, where only one channel data
is sending to soundcard for sound play. and this logic of transferring
and
playing data on sound card is working fine. the data is transfering to the pc
on chunk by bhunk basis.
now i
want to send this data to another pc let say B. But it send data to PC B in
such a way that it misses two chunks of data and send every third chunk.
the logic
of recieving data on both computers A and B is same. (where on PC B, it just
acquiring data and doing nothing on it)
now the
problem arises, when i send data to PC B, after sending data for around 15
minutes, and some times even one minutes, NI card slow down data acquiring,
and ultimately
with in few chunks acqusition, it stops data acquisitions with the following
messege,
DAQmx
Error: Measurements: Attempted to read samples that are no longer availabl
e. The
requested sample was previously available, but has since been overwritten
.
Increasing
the buffer size, reading the data more frequently, or specifying a fi
xed
number of samples to read instead of reading all available samples might cor
rect the
problem.
Property:
DAQmx_Read_RelativeTo

Property:

End of
program, press Enter key to quit
I have
increased the buffer size, but it donot work
Please
helpout
