I've found that if you have your board in bipolar mode (+/- voltages), it uses one bit for the sign. Therefore, you would divide your binary value by the maximum value, and then divide that by two. (The negative number will be shown in Labview). Then multiply that by the range of your board (for +/- 10, you would multiply by 10), and then the scaling factor (if 1V = 30A, then multiply by 30).
Roberto's example is not quite right for 2 reasons. First, he makes the assumption that your board is set for 0-10 volts. Second, if it weren't set for 0-10 volts, the multiplication by 300 to convert to EU wouldn't be correct, either.
