1. Cortex Microcontroller and VEXnet Joystick Pairing Procedure:
a. The Joystick must first be paired to the Cortex Microcontroller before they will work using the VEXnet Keys. Pairing
requires a USB A-A Cable and a VEX 7.2V Battery. This process must be completed each time you use a Joystick
or Cortex with a new mate. A Joystick can only communicate with a Cortex that it has been paired with. During the
Pairing Process, the ID from the Cortex is transferred to the Joystick; thus mating the two units together.

b. Start with the Cortex and Joystick turned OFF.
c. Connect the Cortex to the Joystick using a USB A-A Cable.
d. Connect the 7.2V Robot Battery to the Cortex.
e. Power up only the Cortex.
f. A successful tether is indicated by a Solid Green VEXnet LED on both the Joystick and the Cortex
(See Figure Below)
.
– The Solid Green VEXnet LED must remain ON both units at the same time for a minimum of 5 seconds.
– Disregard the other LEDs as you are only interested in the VEXnet LED.
– Pairing may take up to one minute to complete.
g. Once the units have finished pairing, turn OFF the Cortex.
h. Disconnect the USB A-A Cable from both units.
i. Disconnect the 7.2V Robot Battery from the Cortex.
