When there are several Flowire clusters in an installation, the different clusters must be separated to avoid crosstalk between the clusters. When crosstalk is present, a Flowire unit on one cluster might "jump over" to the other cluster, causing errors in the communication.
Cluster separation can be achieved in two ways:
- Separation by Network Management Key (NMK) (recommended)
- Physical separation
Separation by Network Management Key (NMK)
The recommended way is to separate clusters by using different Network Management Key. The NMK is a kind of a encryption key used by the communication between Flowire units. When implementing different NMKs, it will not be possible for a Flowire unit to "jump" to another cluster with a different NMK.
All Flowires within the same cluster must have same NMK in order to communicate with each other.
Setting the NMK
The NMK is set by logging on to the Flowire unit using a web browser. The Flowire units are automatically assigned an IP address from the network if there is a DHCP server present. You can use the IMT tool to discover the IP addresses of the Flowire units.
If there is no DHCP server on the network, the Flowire units will have a static IP address 169.254.1.10. In order to access the web interface you need to isolate the Flowire units one by one, and access it via 169.254.1.10. Although it is not necessary for the Flowire operation, it is good practice to change the static IP to something unique at the same time, for easier maintenance in the future.
Default NMK: HomePlugAV0123
Physical separation
Both the Flowire units, the power cable, and the link cable must have have a certain distance between them. Minimum distance is 5 cm. Crosstalk might appear if for instance the cables for two different clusters are running on each side of a wall.
