Problem: How can I query my system for Modular Instrument (High-Speed Digitizer, Signal Generator, Digital Multimeter, High-Speed Digital Generator/Analyzer, Switch, RF Signal Generator) device specific information? I'm looking for a method to obtain details such as name, number, and model without opening driver sessions. For DAQmx devices, I can use a DAQmx System property node. Is there a method for Modular Instrument devices? Solution: NI-ModInst is an API that you can use to query information about National Instruments Modular Instrument (MI) devices installed in your system. It allows you to query device specific information without opening driver sessions, and can query device names, models, and serial numbers. It used to support the NI-SCOPE driver only and was released with NI-SCOPE 2.8. Currently, it supports all of the Modular Instruments, including NI-SCOPE 2.9, NI-FGEN 2.6, NI-HSDIO 1.5.4, NI-DMM 2.9, NI-RFSG 1.4, NI-RFSA 2.1 and NI-SWITCH 3.0 . An example on how to use the NI-ModInst API is shown below. 
Note: Launch Measurement and Automation Explorer (MAX) before attempting to query MI devices only supported in Traditional NI-DAQ. If your device is only supported in Traditional NI-DAQ, your device appears in MAX under Devices and Interface»Traditional NI-DAQ Devices and does not appear under Devices and Interface»NI-DAQmx Devices.
