Number of input channels available for PCI-6115 board

[JK Yang]

I am using NI PCI-6115 board for data acquisition. As far as I know,
it has 8 channels for input data acquisition. However, when I tried to
use more than 4 channels, it keeps giving me an error message saying
"Unable to set HwChannel above maximum value of 3." from the Matlab
interface. Could you please correct me if this board supports only
upto 4 channels for data acquisition?
