We have been running laboratory instrumentation through an Edgeport/8 USB->serial. The instrumentation also uses National Instruments digital and serial devices. The Instrument control software loads in the NI serial and NI-DAQmx drivers. With the newest version of the instrument software with NI serial 3.5.1 (which is not needed with the Edgeport/8) is showing conflicts that prevent the system running continuously. A blue screen of death was greeting us in the morning. What version of driver should we be using with the Edgeport/8 to avoid these issues? Also any suggestion on best practices under these conditions.
