Dear All,

I am trying to us an xy566 (ADC) in "Differential Scanned" mode, feeding
3 volts into one channel.

I get 0 volts in the AI record.

I've been told that all unused channels should be grounded. Can anyone
confirm this? Has anyone had a similar experience to me?

I'm convinced that all the jumpers and switches are set correctly for
Differential Ended, +/-10 volts, gain of 1.

I made the driver print out the values of all the channel memory locations
and they all report 0.0.

Thanks in advance for any help,

Andy
