Use the same name (in the tasks/channel/hardware configuration) or all the DAQ devices (say cDAQ).
In your results file also save the DAQ devices serial number (you can read this using a property node shown below) and the computers ID (anything that identifies a unique computer - computer name, network card, IP address, HD serial etc). This way the executable will run on any suitcase, with any PC/DAQ (as long as they are all the same) but will save data that is traceable to a particular suitcase PC and/or a particular cDAQ.
