The Sabertooth 2x10 R/C was primarily designed to be connected to a remote
control receiver. It has a BEC (battery elimination circuit) that puts
5vdc on the red wires to power the receiver. Because the BotBoarduino has
its own power supply, it is necessary to bypass the BEC.</font>
<p><font size="2" face="Verdana">Use an exacto knife to <b>carefully</b>
pry the black tab up and slip the red wire out of the black housing as
shown in Figure 3.</font></p>
<p><font size="2" face="Verdana">Bend the red wires up and use electrical
tape to cover them as shown. This will prevent accidental shorts.</font></p>

Now it's time to set up the A4WD1 for PS2 R/C control. The code supports a pan and tilt and gripper, but they are optional. The Pan and Tilt is installed on the front of the top panel, and the gripper is installed on
the front of the base. If you are adding a pan and tilt and gripper, you will need to change the power bus jumpers according to Table 9 and Schematic 10.</font><p></p>
