Programmatic Detection of NI-IMAQ Devices In LabVIEW

[MGould]

Is there a way to programmatically detect what IMAQ interfaces are attached to a PC?   Obviously this is possible through IMAQdx for 1394, Gigabit, DirectShow, but I've never seen this done using a plain vanilla Analog input.  My goal is to have a program that allows a user to specify what type of video interface he is using for a specific test.  He will have three options, NTSC analog, 1394, and HD-SDI.  Detecting the 1394 and HD-SDI is relatively easy due to the "Enumerate Camera" VI that is provided with the vision acquisition, but its not clear how to do this with analog I/F's.

 To summarize I am trying to programmatically detect in LabVIEW the interface labeled Channel 0 and circled in red below.  Thanks for any input.

Hey MGould,

Unfortunately, there currently is not an IMAQ property node that queries your system for all IMAQ PCI devices. However, there is a possible work around for this. In LabVIEW under the Measurement I/O»MAX  Configuration palette there is a VI called MAX Generate Report.VI that generates a report of all the hardware and software listed in MAX. You could use this VI to generate an html report, then read the report in as a text document, and then use string manipulation to parse the report to get relevant information. This is a bit of a work around and may take some unnecessary process time, but it would allow you to pragmatically determine what hardware you have installed on your machine.

Thanks Ben,  I was afraid of that but that is a good suggestion.

I'm not sure why someone from NI didn't post this but I found this today when working on a seperate issue:

It looks like with a little bit of work this is totally possible.

PS Ben,

Waterloo labs freaking rocks! Real hand gun + Half-Life 2 ftw
