NI 9211A Product Marking--Print the "A" on the device

[Kimberly_Wenger_Austin]

There are a few different versions of the NI USB 9211 Thermocouple Module.  The USB 9211 is now a legacy device and the USB 9211A is the upgraded version for higher performance.  The issue that I have seen when using the USB 9211A for Mac is that the DAQmx Base drivers that support the USB 9211 are different than the drivers that support the 9211A, but the device itself does not specify which version of the 9211 the customer has. DAQmx Base 2.1 supports the 9211 and DAQmx Base 3.2 supports the 9211A, but the device will not be recognized if the incorrect driver is downloaded.

My suggestion would be to print the "A" after the 9211 on the new devices to make sure that the customer knows which driver to download for their device.

The USB 9211 and the USB 9211A both use the same module (NI 9211) so I don't think it makes sense to print "A" on the module itself.

The difference between the two is that the USB-9211 uses the 9161 carrier, and the 9211A uses the newer 9162 carrier.

I'll agree that the distinction is confusing at best.  Future carriers (like the 9181 which is already released) will enumerate just like a cDAQ chassis that only has 1 slot which I think should be more straightforward, but unfortunately these carriers are not supported in DAQmx Base (as of me writing this comment). The plus side is that these carriers will support all modules that are supported by a regular cDAQ chassis.
