FAQ: What does "Warning:2003 The IO node KEYBOARD is used in real-time Sequence" mean?
#1
The 'Is Real-Time' property forces the operating system to devote all available resources to an experimental sequence, which is important for maintaining precise timing.

However, on older Display PCs with a single-core processor, this can lock out other essential processes, potentially causing a loss of keyboard or mouse input. This is why the warning message appears.

This is not an issue on modern multi-core or hyper-threaded PCs, as they are designed to handle multiple processes simultaneously. Therefore, this warning can be safely ignored on most modern computer configurations.
