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.
The DAQmx Reset Device VI sets all terminals on the I/O connector to high-impedance state but aborts any running tasks associated with the device.

output terminal specifies the terminal on the I/O connector to set to high-impedance state. A DAQmx terminal constant lists all available terminals on installed devices. You also can specify an output terminal by using a string that contains a terminal name. | ||||||

error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function runs normally and passes the error in value to error out. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
