Use the DAQmx Signal Routing VIs to route signals from one terminal to another.

Palette Object Description
DAQmx Connect Terminals

Creates a route between a source and destination terminal. The route can carry a variety of digital signals, such as triggers, clocks, and hardware events.

DAQmx Disconnect Terminals

Removes signal routes you created by using the DAQmx Connect Terminals VI. The DAQmx Disconnect Terminals VI cannot remove task-based routes, such as those you create through timing and triggering configuration.

DAQmx Tristate Output Terminal

Sets a terminal to high-impedance state. If you connect an external signal to a terminal on the I/O connector, the terminal must be in high-impedance state. Otherwise, the device could double-drive the terminal and damage the hardware. If you use this VI on a terminal in an active route, the VI fails and returns an error.
