Why am I getting error 200077 on the PXIe-6124 system

[renwei]

My program works well for DAC 6115 and 6110. Now I'm going to apply it to the PXIe-6124 (BNC 2110 borad). When I switch the coupling mode from DC to AC, Error : 200077 occured at Property Property Node DAQmx Channel. More in the attachment. Can anyone help me solve this problem? thanks a lot.

renwei,

Thank you for using the NI Forums. The reason that you are getting this error is because the PXIe-6124 only supports DC Coupling. If you look at the specifications from the PXIe-6124 it has this as "Input Coupling". PXIe-6124 Specifications. As for the 6115 and the 6110 they support both AC and DC coupling, (PCI-6110 Specs) so it appears that your program is trying to set the coupling of the PXIe-6124 as AC Coupling. As long as you set the coupling for the 6124 to DC you will have no problems. Hope this helps.
