DAQmxTristateOutputTerm
int32 DAQmxTristateOutputTerm (const char outputTerminal[]);
Purpose
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 function on a terminal in an active route, the function fails and returns an error.
DAQmxResetDevice sets all terminals on the I/O connector to high-impedance state but aborts any running tasks associated with the device.
