Why am I Getting All Zeros From My 923x in LabVIEW FPGA? I am using LabVIEW FPGA to acquire data from a 923x module. When I run my VI, I am only getting zeros returned from my I/O Node. Why is this happening? URL: http://digital.ni.com/public.nsf/allkb/36487433B85F49AC862575150071AA0D

Incorrect Value when Passing LabVIEW Binary String Control Defaults from TestStand When I specify to pass the default value for a LabVIEW string control in my TestStand module prototype, I do not get the correct string passed to my VI if I am passing the parameter as a binary string. Why does this happen? URL: http://digital.ni.com/public.nsf/allkb/3DA82432236D7C06862575140055F14B

Self Test Function Does Not Work For PXI-5404 In LabVIEW or LabWindows/CVI When calling niFgen_self_test in LabWindows/CVI 8.1 to 8.5 or the niFgen Self-Test.vi in LabVIEW 8.6 for the PXI-5404, there is no message passed back to indicate whether the device passed or failed the self test. If the device fails the self test the error handler does URL: http://digital.ni.com/public.nsf/allkb/4B221E17D83AE9A68625751400671F57

TestStand User Interface in LabVIEW Hangs I am using a TestStand user interface built in LabVIEW and sometimes it hangs. What are possible reasons for this hang? URL: http://digital.ni.com/public.nsf/allkb/7EFE8993027506F38625751300545124
