help with Operator Interface and FRC robot Controller

That means your RC is in "programming mode". Either download code to it using the IFI Loader and a serial cable, or hit the reset button on the RC.

tdlrali is correct, Your RC will go into that mode if it does not have a program in it (occasionally the program gets corrupted for reasons unknown, and needs to be reflashed.)

To do this, download the default code from IFI's website (www.ifirobotics.com) as well as IFI_Loader, if you haven't already got those, connect your PC to the Robot Controller with a serial cable (and usb-to-serial converter if necessary), press and hold the PROG button on the controller for about 3 seconds (you shouldn't see any change in the lights on the unit), and then download the code using IFI_Loader. Once you click download on IFI_Loader, you should see some status messages go by on its message bar, and the Program State LED on the Robot Controller should begin to flash yellow. This means the controller is in the act of receiving a program.

Once it is complete, all LEDs on the Robot Controller should return to their normal green state.
