Commissioning
Commissioning is the process by which PTM 215B is learned into a receiver (actuator, con-
troller, gateway, etc.).
The following two tasks are required in this process:
Device identification
The receiver needs to know how to uniquely identify this specific PTM 215B device.
This is achieved by using a unique 48 Bit ID (Source Address) for each PTM 215B
device as described in chapter 4.4. In addition, up to 4 byte of Optional Data can be
configured as described in chapter 6.7.8
Security parameter exchange
The receiver needs to be able to authenticate radio telegrams from PTM 215B in or-
der to ensure that they originate from this specific device and have not been modi-
fied as described in chapter 4.6.3. This is achieved by exchanging a 128 Bit random
security key used by PTM 215B to authenticate its radio telegrams.
PTM 215B provides the following options for these tasks:
NFC-based commissioning
The PTM 215B parameters are read by a suitable commissioning tool (e.g. NFC
smartphone with suitable software) which is already part of the network into which
PTM 215B will be commissioned. The commissioning tool then communicates these
parameters to the intended receiver of PTM 215B radio telegrams. NFC-based com-
missioning is described in chapter 6
Camera-based commissioning
Each PTM 215B module contains an optically readable Data Matrix Code (DMC)
which identifies its ID and its security key. This DMC can be read by a by a suitable
commissioning tool (e.g. smartphone) which is already part of the network into
which PTM 215B will be commissioned. The commissioning tool then communicates
these parameters to the intended receiver of PTM 215B radio telegrams. The DMC
structure is described in chapter 8.1.1
Radio-based commissioning
PTM 215B can communicate its parameters via special radio telegrams (commission-
ing telegrams) to the intended receiver. To do so, PTM 215B can be temporarily
placed into radio-based commissioning mode as described in chapter 5.3
