Q Cut a 12 length of the twisted-pair red black cable. Strip I of insulation from the wire on both ends. Q From underside of IR board insert red wire into hole marked and black wire into hole marked . Solder from top of board. Q Mount other end of wire to outside pins of a three-pin male connector. Use guideline shown in Section . The infrared transmitter plugs into the connector labelled IR OUT on the Microprocessor Board see Figure with the red lead inserted into the end marked on the board. The Motor Switch Board The Motor Switch Board allows manual control of up to four motors. This is useful when testing and debugging mechanisms because the motors can be switched on forward backward and off easily. It is important to realize that the amount of power delivered to the motors by the Motor Switch Board will be different than the amount delivered when the motors are driven by the electronics on the Microprocessor Board. The Motor Switch Board has diode circuitry to simulate the power loss of the Microprocessor Board s control electronics but there will still be a difference. Motors driven from the Expansion Board will operate at even less power than those driven by the Microprocessor Board. The careful designer will test mechanisms both from the Switch Board and from the Microprocessor Board before committing to them. Assembly Instructions Figure provides a reference to parts mounting on the Motor Switch Board. 1 n Get Motor Switch Board and determine which side is the component side. The component side is marked with the parts placement layout. . CABLE AND CONNECTOR WIRING 37 Figure Motor Switch Board Component Placement 2 n Diodes. These diodes have black epoxy bodies.
