Timing Guidelines
When using the AI, AO, and DIO channels on the NI-9381 concurrently, follow these
guidelines to ensure high accuracy.
■
Use a single I/O Node to access AI and AO operations to ensure proper
sequencing.
■
Configure the line direction of the DIO channels before performing
operations on other channels or stop all operations to change the line
direction of a DIO channel.
