How to read the camera string type attributes?

[Yinsheng]

I tried to read the string type attributes of my line scan camera.  The serial command is CORR:OFFSET?, I tested this command in NI Camera File Generator, it worked, the returned string was "ON". Then I tried to use imgGetCameraAttributeString in my C++ program to read this attribute, first I added an attribute "Offset Status", I chose it as numeric type, then I added serial action CORR:OFFSET?\r, but it returned some wrong characters. Has anyone have the experience to read the string type attribute from camera? Thank you.

If the returned string in the Camera File Generator was "ON" is there a particular reason why you set the attribute to be a numeric type? What is the returned characters you are receiving currently? You might try setting the attribute to return a string, and see if this fixes the problem.
