Hi,
I have a problem to use that DAQPad as pulled-low mode rather than pulled-high mode.Basically that DAQPad-6508 has a front panel switch to change the power-up state selection for 96 channels.
But jumperd the switch to pulled-low mode to use 96 channels, both DI and DO will not work properly. DI does not get any state change, and DO works like pulled-high mode.
Insted jumperd to pulled-high mode, both DI and DO work fine at this time.
Why the pulled-low mode does not work properly?
Is there any difference between line connection as to the mode selection?
