Don't worry about the LED on the Operator Interface (OI). The OI doesn't have the actual code from the robot on it, so it lights up the Code Error LED if the robot should be running (according to the OI) but is not sending signals back. Thus, when downloading code, the code error LED should be red, since the robot has no working code. As long as the program status LED on the robot is solid orange, you should be fine - you don't even need the OI to download.
