Contact Nipples assignment
PTM 21x devices provide four contact nipples. They are grouped into two channels (Channel
A and Channel B) each containing two contact nipples (State O and State I). Resulting the
nibbles are referred to as: AO, AI, BO, BI.
The state of all four contact nipples is transmitted together with a unique device identification
whenever the energy bow is pushed or released in an EnOcean Telegram. The exact coding
is defined the EEP Profile. Which EEP is used is selected based on the Radio Standard (ERP1
or ERP2) and operating mode (normal or secure). See chapter 2.3 for details on used EEPs.
The picture below shows the arrangement of the four nipples and their designation:

Available EnOcean Equipment Profiles
The (EnOcean Equipment Profile) EEP profile defines how the data inside the EnOcean tele-
gram are coded. For the PTM it practically means how the nibbles and energy bow state are
represented. Based on the specified EEP the receiver knows how to interpret the incoming
telegrams from the PTM Module.
