10BASE-T1S uses Differential Manchester Encoding (DME). DME encodes data based
on whether there is a transition within the clock period, indicating the logical state of
the signal. If there is no transition within the clock period, the data state is logical 0. If
transitions (either positive or negative) occur within the clock period, 10BASE-T1S
operates in a half-duplex bus configuration with a maximum length of 25 meters. It
supports multipoint connections with two to eight nodes. The "S" in the standard name
denotes short-range implementation. The intended use of 10BASE-T1S is to replace
existing bus architectures that often result in "communication islands," such as CAN,
CAN FD, LIN, and RS-485.
