A/D Timeout

Hi
I’m trying to use a PCL-711B card with comedi.  When the sample program
‘tut1’ is run, the A/D conversion is not within an acceptable range and an
A/D time out is given.  None of the other subdevices respond favourably
either.  Changing the interrupts doesn’t help either (interrupts 3 through 7
were tried with no luck).  Below are some of the configuration commands used
and the card’s output.

Please help,
Daniel
