Comedi on RT Linux

Dear All,

I am new to the comedi.  I have a 64 analog input Computing Measurement Card.  
PCI-DAS6402/16.  I can get the analog input on a single channel by 
using "comedi_data_read".  But when I using the following to get two or more 
channels, the data are obviously wrong:

"
..
chan=0;
comedi_data_read(device, 0, chan, 0, aref, data1);
chan=1;
comedi_data_read(device, 0, chan, 0, aref, data2);
chan=2;
comedi_data_read(device, 0, chan, 0, aref, data3);
..
"

Can anybody tell me what's wrong with this?  Is there anybody can give me some 
sample code or advices on this card?  I have got blocked by this card for a 
long time.  Thank you very much!

Best regards

Haihong Zhu
