The first five lines of the 6533 card will be used for data transfer and communication with the SCXI chassis. Therefore, you should not be making a virtual channel of port 0 of the 6533. You can get access to the unused lines on that card, however, you'll need a feedthrough panel (like an SCXI-1180 module) for that.
I am assuming that you are trying to read data on lines 4 through 7 on the 1162HV module. In that case, you can go ahead and make a virtual channel for the 32 bit port on the 1162HV. You need to use that virtual channel in the 'portlist' input. You can also enter the string: sc1 ! md1 ! 0 in the portlist.
In order to check if there is any data in the binary file or not, just check its size by looking at the file properties.
You should be able to view the da
ta using the digital data reader vi as long as you specify the correct file name and reading parameters. Look at the vi description by brining up the context help for more details.
If you still have trouble reading data, then I would suggest that you run the scxi example vi for the 1162 module. This example is shipped with labview and is located in the labview/examples/daq/scxi/ folder. It is a simple vi for reading in data from the 1162HV module.
