10BASE-T1S Trigger

10BASE-T1S trigger supports frame events / error checks and Clause Trigger pattern match on Destination / Source Address, Ethertype / Length, and Data. The physical layer is a single-pair differential link.

TravelBus provides dedicated 10BASE-T1 channels; for LA, verify the Data wiring. See Settings for channel prefixes and Clause Trigger for clause flow.
