3.1.1  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 password. This password allows the powerline adapters to understand the encrypted 
information sent in the powerline network. 
By default the PLA-4xxs are all configured with the password 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 password on the 
powerline adapters you want to allow to communicate in your powerline network.
3.1.2  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 configuration 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).
3.2  Starting the Configuration Utility
To launch the PLA-4xx Series Configuration Utility simply double click on the

3.3  Configuration Screen 
Use the Configuration screen to see which devices are recognized by your powerline 
network, gain access to managing remote devices (those not directly connected to the 
computer running the configuration utility) and change the powerline network password. This 
screen opens up when you launch the configuration utility.
