Hello,
The problem is probably related to a conflict between the driver and the controlling module in your SCXI chassis. I have heard of this problem before when trying to acquire data from an SCXI-1125 that is slot 3 or higher of a SCXI chassis running in RT, and it resulted with that exact error.
There was no fix such as upgrading to a newer version of the driver or anything like that. Rather, the problem was shown to occur only when the SCXI-1125 module was used to control the SCXI chassis. If they used any module other than the 1125 to control the chassis, then there was no problem.
My suggestions to you are to try this exact thing - do not use an SCXI-1125 module as the controller for your chassis. If this doesn't happen to be the case, or this does not
work out for you, then please post back to this discussion so we might be able to solve this problem. If you happen to post back, please list some more information such as driver version, OS, SCXI chassis, controlling module/slot, etc.
Best of luck.
