IMAQIOSignalState Constants

IMAQIOSignalState constants are the constants for the value parameter of the following methods:


  • IMAQIO_SIGNAL_STATE_HIGH—Drives the line high when the signal is True.
  • IMAQIO_SIGNAL_STATE_LOW—Drives the line low when the signal is True.
  • IMAQIO_SIGNAL_STATE_HI_Z—Disables output on the line. This option is valid only for TTL output signals.
