Yes, this is possible. It is even the default if you use RTnet's startup script and config (only one NIC is configured, and if there are two NICs of the same type, only the first one is claimed by RTnet). > > (The whole point is to have a network of PCs running RTnet, so that > their clocks are synchronized.

Note that the measurement jitter /may/ still be in the same order of your travel delays. Jan
