AV500 2-port Powerline Adapter
Chapter 5 Advanced Feature: How to Use the Pair Button
5.1 Set Up a Secure Powerline Network
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 Membership Key (NMK). Otherwise, they cannot unscramble the encrypted
data sent in the powerline network.
The Pair button allows you to set up a secure powerline connection with other HomePlug AV compliant
powerline devices which also support the Pair feature.
You can connect a number of devices on a powerline network, but you can use the Pair button on only
two devices at a time.
Create a Powerline network using the Pair button
：
Step 1. Press and hold the Pair button of Powerline adapter A for 1 second, the Power LED will start
flashing.
Step 2. Press and hold the Pair button of Powerline adapter B for 1 second, the Power LED will start
flashing.
(This must be done within 120 seconds after pressing the Pair button of Powerline adapter A.)
Step 3. Wait for about 60 seconds while your Powerline adapter A and B are connecting. The Power
LED on both adapters will stop flashing and become solid light when the connection is made.
Join an existing Powerline Network:
Powerline adapter A and Powerline adapter B form a HomeplugAV Network, Powerline adapter C wants
to join this network.
Step 1. Press and hold the Pair button on Powerline adapter C for 1 second.
Step 2. Press and hold the Pair button on Powerline adapter A/B for 1 second.
(This step must be taken within 120 seconds after step 1 is finished.)
Step 3. Wait for about 60 seconds while your Powerline adapters are connecting. The Power LED on
Powerline adapter A/B and C will stop flashing and become solid light when the connection is
made.
Note:
The sequence of Step 1 and Step 2 can be exchanged.
Leave an existing Powerline Network:
Powerline adapter A, B and C have formed a HomeplugAV Network. The user wants to remove one
device (Powerline adapter A) from this network.
Step 1. Press and hold the Pair button on Powerline adapter A for about 8 seconds and then release
the button. (All LEDs of powerline adapter A will momentarily go off.)
Step 2. Wait until the Power LED of powerline adapter A lights up steadily, indicating that it has already
left the powerline network.
