rocker was used, then Rocker A is coded.

For more information on the structure of the teach-in telegram please refer to the EnOcean

Security specification [3].

If the teach-in process is not successful, please repeat the procedure. Due to the

enhanced telegram length of teach-in telegrams in secure mode only a single

teach-in sub-telegram is sent at every actuation (no redundancy).

3.3 Switching between modes

PTM 21x can be switched between normal mode and the secure modes by a special button

combination SBC. There are three types of SBC:

 2 nipple SBC – pressing both nipples of a channel i.e. AI & AO or BI & BO.

This SBC is used to enter the secure mode with implicit RLC – legacy, not recom-

mended. The picture below shows both variants of this combination.
