Is there a coordinate based input for the OCR function?  And if not, how can you move the ROI dynamically as the product moves?

OCR is a very simple VI. There is no input for a coordinate system. I would suggest either using IMAQ Extract with a rectangle having the orientation needed to make the characters upright and including the characters. Or, possibly better, use the IMAQ Rotate to rotate the image to make the characters upright. I think those are your best options.
