The text boxes inside the EASunlock software hold values that are returned from the EAS. A specific rule is that the value of 255 should never show up in these boxes. When you see a value of 255 in the EASfaults or EAScalibrate application this is incorrect. To fix the situation, simply try to read the faults or read the heights again. Usually if you just re-read the memory locations again, the EASunlock software will grab the correct returned value. The software just missed the value. Try again and it should be ok. If after trying a few times, you are still getting a value of 255, then try adjusting the One Byte delay 20-30ms higher.
