DAQ device available by type instead of device number

[C.vanLeuken]

For each device, MAX will use an unique device number.

This is no problem with fixed measurement equipments.

With USB devices this may become a problem.

On a school, a student will work with different combinations of computer and device.

If the student wants to use his program with a different device, he will get an error.

Even if the device is the same type, but has a different serial number.

To solve it, the student needs to open all DAQ routines and to alter the device number.

Or he needs to change the DAQ assistant routine into a VI and change the constant device number by a routine as shown in DAQmx device to use.vi.

 

This same problem occurs when using NI-IMAQdx devices.

Solution:

Make it possible to select a device by type instead of a device by number.

Why aren't you teaching them to rename the devices away from the default values of "DevN"?  Also, it is trivial to include a device identifier field settable by the user.

mzaleski, if you use the DAQ assistant to control the hardware (which I do and would expect a student to do) I can't see any way for the user to change the device identifier. Is there such a feature? Another option for this type of situation would be an option for devices to remove themselves from MAX when the hardware is unplugged so that each time a new device is plugged in it would be dev1.
