Obtaining the security key via the product DMC code
Each PTM 215B module contains a DMC code on its product label which identifies source
address and security key of the module, see chapter 5.2.
The DMC code of the device used for this tutorial encoded in the DMC code format up to
revision DB-05 is shown in Figure 43 below.
Figure 43 – Example DMC code (used up to DB-05)
This DMC code can be read using a suitable DMC code reader (e.g. QRbot smartphones).
The content of this example DMC code is:
PTM215BIDE215000019B8OOB
3DDA31AD44767AE3CE56DCE2B3CE2ABB
The structure of the DMC code is described in chapter 8.1.1. The location of the security
key in above DMC string is marked red for reference. This means that the security key of
this device is:
3DDA31AD44767AE3CE56DCE2B3CE2ABB
Note that the device label has been updated starting with product version DC-06 as de-
scribed in chapter 8.2.
Figure 44 below shows the same information encoded according to that.
Figure 44 – Example QR code (used starting with DC-06)
The QR code shown above encodes the following text:
30SE2150Z
3DDA31AD44767AE3CE56DCE2B3CE2ABB
+30PS3221-A215+
S01234567890123
The security key can then be obtained from the “Z” field as highlighted in red above.
