We are using an ultrasonic range finder (Maxsonic MB1300), and we need to use the RoboRio to trigger the pulse. The sensor has an input pin that accepts either 0 volts (low) or 5 volts (high). Does the RoboRio have a controllable output that we can drive to low and high?
Use a roboRIO Digital line configured to be an Output (DIO)
DIOs are nominally 3.3V. PWM and relay ports are 5V; for this application, relay ports make more sense.
