Reading multiple channels with DAQcard-1200

Hi

I want read the 24 channels of digital input. First I
configure the digital port with:

for (i=0; i<24; i++) 
{
 aux = comedi_dio_config(dispositivo, subdisp, i,
COMEDI_OUTPUT);
}

NOTE: aux variable must return 0? I get '1'

---

I read digital port with:
aux = comedi_dio_bitfield(dispositivo, subdisp, 0,
&bits);

If I print aux value I get always 2**24 (all the bits
set to 1) although I change input or disconnect the
cable

Any suggestion?

Thanks for your time
