Description
Specifies the channel state after the session is initiated but before the first waveform sample is generated. The channel changes to the Initial state once the data operation has been initiated. When the Start trigger is asserted, the Initial state is replaced by the first sample in the waveform.
This attribute is valid only for generation sessions.

Note NI 656x devices do not support the tristate Initial state. |
Defined Values:
| NIHSDIO_VAL_TRISTATE (24) | Sets the channel to a high-impedance state. |
| NIHSDIO_VAL_LOGIC_HIGH (1) | Sets the channel to a logic-high (high level) state. |
| NIHSDIO_VAL_LOGIC_LOW (0) | Sets the channel to a logic-low (low level) state. |
| NIHSDIO_VAL_HOLD_LAST_VALUE (27) | The channel retains its previous value. |
