This information is also located in the DAQmx help file. You can launch this from either:
- Windows Start Menu » Search: NI-DAQmx Help or
- in NI MAX, go to menu Help » Help Topics » NI DAQmx » NI DAQmx Help.
Once inside help, it will be in the section NI-DAQmx Key Concepts
» Channels and Tasks in NI-DAQmx
» Channels: Physical, Virtual, Local Virtual, and Global Virtual
» Physical Channel Syntax
When using a comma-separated list, ensure that you're specifying the device's name in each entry in the list so that DAQmx knows which device you're referring to in each entry, since there may be more than one channel with the same name (for example, "ai0") in your system.
