1 Prerequisites
Before installing a meter, the TEK and DEK keys must be imported into READy. The TEK key is the module’s encryption key and
the DEK key is the meter’s encryption key.
In READy, navigate to Configuration and Infrastructure to see if a TEK key has been imported for a P2P module. In this guide,
the module with NB-IoT S/N: 79719092 is used. It can be seen in figure 1 that several devices have been imported. The date of
the last reception of data is shown, and if there is a problem with the device, a red triangle appears. For the marked module,
there has not been contact yet, and therefore, the field Last seen is empty.

Overview of imported infrastructure devices
The DEK key appears as an imported meter under Meters. In this guide, the MULTICAL® 603 meter with S/N: 80954289 is used.
Once the module has transmitted data for the first time, the connection between the module and the meter is established
automatically in READy. The address under Infrastructure reflects the address provided for the attached meter.
