PTM 215B – 2.4 GHZ Pusbutton Transmitter Module

2.7 PTM 215B 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:

n 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 2.9.4. In addition, up to 4 byte of Optional Data can be configured

as described in chapter 2.11.4.1

n Security parameter exchange

The receiver needs to be able to authenticate radio telegrams from PTM 215B in order to

ensure that they originate from this specific device and have not been modified as de-

scribed in chapter 2.10. This is achieved by exchanging the 128 Bit random security key

used by PTM 215B to authenticate its radio telegrams.

PTM 215B provides the following options for these tasks:

n NFC-based commissioning

The PTM 215B parameters are read by a suitable commissioning tool (e.g. NFC

smartphone) which is already part of the network into which PTM 215B will be commis-

sioned. The commissioning tool then communicates these parameters to the intended

receiver of PTM 215B radio telegrams. NFC-based commissioning is described in chapter

2.11

n Radio-based commissioning

PTM 215B can communicate its parameters via special radio telegrams (commissioning

telegrams) to the intended receiver. To do so, PTM 215B can be temporarily placed into

radio-based commissioning mode as described in chapter 2.8.2

n Camera-based commissioning

Each PTM 215B module contains an automatically 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 pa-

rameters to the intended receiver of PTM 215B radio telegrams. The DMC structure is

described in chapter 3.3.1
