NOTE: The MXP connector has 2 Digital I/O pins which are dedicated to the I2C interface. MXP
Digital I/O Pin DIO14 is used for I2C SCL and DIO15 is used for I2C SDA. Since the navX MXP
I2C interface is always active, these pins must not be used for any other purpose.
Analog Inputs
Each of the 4 Analog Input pins on the MXP connector has a corresponding 3-pin connector
(DC Voltage, Ground and Signal). On the RoboRIO, these signals are routed to the internal
Analog-to-Digital Converters (ADCs).

Analog Outputs
Each of the 2 Analog Output pins on the MXP connector has a corresponding 3-pin connector
(DC Voltage, Ground and Signal). On the RoboRIO, these signals are generated by the host
computer's internal Digital-to-Analog Converters (DACs).
