Channel Names Cause Incorrect Analog Output on NI USB DAQ Devices

Primary Software: Driver Software>>NI-DAQmx
Primary Software Version: N/A
Primary Software Fixed Version: N/A
Secondary Software: N/A
Hardware: CompactRIO>>Analog Output Modules>>NI 9263, CompactDAQ>>Analog Output Modules>>NI 9265, CompactDAQ>>Analog Output Modules>>NI 9264

Problem:
I am generating a voltage on the analog output of my USB devices, such as the NI USB-6008/9 or a C Series device such as the NI USB-9263. If the channels in my task have a numeric value at the end of the channel name, then my task generates incorrect values. Why is this and how can I fix it?

Solution:
This behavior is a bug in NI-DAQmx 8.5 but was not present in previous versions of the driver. It has been fixed for NI-DAQmx 8.6 and later. Upgrade to the most recent version of NI-DAQmx to resolve the issue.
