Virtual Channel Device Memory

[Hooovahh]

I can calibrate a NI analog in DAQ card.  I calibrate it so that 1volt in is read at be 1.00000000000 in the software.  If I take that card to another computer it keeps that calibration information because it is stored in the card in EEPROM (or something).

I was having a discussion with someone today and they asked the question.  Can Virtual Channels be stored in the device it a similar to calibration?  The answer (as far as I know) is no you can't, but is there a reason we can't?  I realize the non-volitile memory on the card may be small but is this a feature NI has ever thought about?  Seems like a good idea to have the option to bring along any scaling and channel information with the card to a new PC.

Hi Hoovahh,

Yes you are right we cannot currently store virtual channels on a device but that is because they are a software configuration not a hardware configuration. It is an instruction that tells the drivers how to interpret the data being read off the buffer before it goes into LabVIEW. You can save tasks in MAX which contain scaling and channel information but you are right as of now we have no capability to save the virtual channel.
