reading/writing cDAQ Hardware Property node information (NI9220 or general)

[James_S]

I have a CompactDAQ system with a 9188XT chassis and several 9220 A/D modules. Using a Hardware Property node, I am able to read "Calibration Notes" (CalNotes) and it returns an empty string.  I would like to store some information on the card, does anyone know how to write to this (or a similar) property?  I could use the Comments section for the 9188XT, but these are more easily visible (and editable) in MAX.  In addition, this field is limited to 64 characters.  Thank you.

Thanks Tyler, that showed the exact format for what I wanted to see.  Unfortunately the comments field is only 4 bytes, so I'll have to go a different direction.
