Chapter 5 The Configuration Utility 5.1.1 Powerline Network Security When the PLA-4xxs communicate with each other, they use encryption to protect the information that is sent in the powerline network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message. The HomePlug AV standard uses 128-bit AES (Advanced Encryption Standard) to safely transmit data between powerline adapters. For the powerline adapters to communicate with each other they all need to use the same network name. This network name allows the powerline adapters to understand the encrypted information sent in the powerline network. By default the PLA-4xxs are all configured with the network name HomePlugAV, this allows you to simply plug the devices in and not worry about setting up security. If you want to enhance the security on your powerline network, you can change the network name on the powerline adapters you want to allow to communicate in your powerline network. 5.1.2 Device Access Key (DAK) In order to manage the powerline adapters on your powerline network you must enter the adapters' password in the PLA-4xx Series Configuration Utility. This password is called the DAK (Device Access Key) password. This password is printed on the powerline adapter itself. You don't need to enter the DAK password for the powerline adapter directly connected to the computer running the utility (local powerline adapter), you only have to add the remote powerline adapters' passwords (those in your powerline network, but not directly connected to your computer). 5.2 Starting the Configuration Utility To launch the PLA-4xx Series Configuration Utility simply double click on the configuration icon on your desktop.

5.1.1
Powerline Network Security
When the PLA-4xxs communicate with each other, they use encryption to protect the
information that is sent in the powerline network. Encryption is like a secret code. If you do
not know the secret code, you cannot understand the message. The HomePlug AV standard
uses 128-bit AES (Advanced Encryption Standard) to safely transmit data between powerline
adapters.
For the powerline adapters to communicate with each other they all need to use the same
network name. This network name allows the powerline adapters to understand the encrypted
information sent in the powerline network.
By default the PLA-4xxs are all configured with the network name
HomePlugAV
, this allows
you to simply plug the devices in and not worry about setting up security. If you want to
enhance the security on your powerline network, you can change the network name on the
powerline adapters you want to allow to communicate in your powerline network.
5.1.2
Device Access Key (DAK)
In order to manage the powerline adapters on your powerline network you must enter the
adapters’ password in the
PLA-4xx Series Configuration Utility
. This password is called the
DAK (Device Access Key) password. This password is printed on the powerline adapter itself.
You don’t need to enter the DAK password for the powerline adapter directly connected to the
computer running the utility (local powerline adapter), you only have to add the remote
powerline adapters’ passwords (those in your powerline network, but not directly connected to
your computer).
