Installation
I/O Expansion
DC Voltage Selection
Using the provided jumper, select the DC Voltage which will be routed to each of the connector blocks.
Select from either 3.3V or 5V DC. This regulated voltage is supplied directly by the host computer (e.g.,
the RoboRIO).
I/O Summary
Each of the I/O pins on the MXP connector has a corresponding 3-pin connector (DC Voltage, Ground
and Signal). The orientation of the Ground, Power and Signal pins for each of the Digital I/O, Analog
Input and Analog Output pins is as follows:
Digital I/Os
Each of the 10 Digital I/O pins may be configured for use as either DigitalInputs or DigitalOutputs, PWM
(Outputs) or Counters (Inputs).
Additionally, multiple (either 2 or 3) DigitalInputs may be used to form an QuadratureEncoder input.
