Compare the Cerebot 32MX4 board to the picture below. Note that the blue shorts are attached to each jumper as depicted. Remove the rubber feet from the bottom of the corners of the Cerebot32MX4. Attach the standoffs to the board using the corresponding mounting screws. Mount the Cerebot 32MX4 board to the top side of the metal platform. Be careful not to cross thread screws while mounting the Cerebot 32MX4 board. www.digilentinc.com page 5 of 9 Copyright Digilent, Inc. All rights reserved.

Connect the two PmodHB5 modules to port JD on the Cerebot 32MX4 board using the 2x6 Pin to dual 6 pin cable. Use the marker on the cable connector to ensure that pin placements are in alignment when connecting the boards. 10. Strip 1/2-inch of insulation from both ends of all red and black 22 gauge power wires. www.digilentinc.com page 6 of 9 Copyright Digilent, Inc. All rights reserved.

MPLAB can now be used to program the RDK_RemoteControl reference design to the board. For more information on how to program the Cerebot32MX4 using MPLAB, see the Cerebot32MX4 LED Demo project at www.digilentinc.com. Note that running the reference design that turns the motors requires that the power select mode jumper J12 be shorted to External Power. Once the board has been programmed with the reference design, movement on the joystick should cause the robot to move in a similar fashion. Orient the Remote Control RDK Kit as shown below. www.digilentinc.com page 9 of 9 Copyright Digilent, Inc. All rights reserved.
