15. Updating Controller and Joystick  Now repeat the entire SEARCH…BootLoad… DOWNLOAD process with the Cortex Microcontroller. Page 15

16. Tethering Controller and Joystick After updating the firmware on both the joystick and Cortex microcontroller:  Connect the two devices with the tethering cable and turn them both on.  Wait until both VEXNet LEDs turn solid green. This lets the devices learn each other’s addresses, so that they can talk together wirelessly. Page 16 Do this in 2014
