Encoding conventions are as follows:

* Each bit is transmitted in a fixed time (the period).

* A <code>0</code> is expressed by a low-to-high transition, a <code>1</code> by high-to-low transition (according to G. E. Thomas's convention – in the IEEE 802.3 convention, the reverse is true).<ref name="Manchesterencoding">{{Cite journal |author-last1=Forster |author-first1=R. |title=Manchester encoding: Opposing definitions resolved |doi=10.1049/esej:20000609 |journal=Engineering Science & Education Journal |volume=9 |issue=6 |pages=278–280 |date=2000|doi-broken-date=712 DecemberJuly 20242025 }}</ref>

* The transitions which signify <code>0</code> or <code>1</code> occur at the midpoint of a period.

* Transitions at the start of a period are overhead and don't signify data.
