3. 2 3 1 JUMPER SHUNTS The 2 pin jumper shunts are installed on 3 pin headers and connect the middle pin to one of the outer pins Move the jumper to the side labeled with the desired voltage REV 11 1100 UM 00 Copyright 2014 REV Robotics LLC 2 3 2 SOLDER JUMPERS Next to each 3 pin power rail header is a set of two solder jumpers These provide a more secure way to select the voltage rail but require the use of a soldering iron To select a voltage rail first remove the jumper shunt Then on the solder jumper associated with the desired voltage label flow a small quantity of solder onto the fork shaped pads so that the connection is made between the prongs See Figure 2 2 for a before and after example of selecting 5 0V for DIO Vcc using the solder jumper CAUTION Take care not to short both solder jumpers This can create a short between the 5 0V and 3 3V rails and damage the roboRIO It is also recommended that you remove 2 pin jumper shunt when using the solder jumpers to prevent accidental shorting of the rails See Figure 2 2 for examples of proper solder jumper usage SOLDER JUMPERS BSOLDER JUMPERS c E i Solder Bead 5 B JP6 3 3 5 0V 3 3 5 0V DIO DIO Figure 2 2 Solder Jumpers 2 3 3 ANALOG SIGNALS The 5 0V rail is directly connected to the analog headers because the roboRIO s Analog to Digital Converter ADC measures between OV and 5 0V Analog ground AGND is b
