Powerline PL500 Series Adapter
CAUTION:
Do not press the Security button until the Power and Performance LEDs
for both adapters are lit solid. Pressing the Security button too soon can
temporarily disable Powerline communication.
If Powerline communication is disabled, reset the Powerline adapter to its factory default
settings. (Press the Factory Reset button for two seconds, then release it).
4. Press the Security button on the first Powerline adapter for two seconds.
• The Power LED blinks after you release the button.
• The Powerline adapter generates a random encryption key that all other Powerline
devices on the network must use.
At this point, the Powerline adapters cannot communicate with each other.
5. Within two minutes, press the Security button on the second Powerline adapter for two
seconds.
• The Power LED blinks after you release the button.
• This process allows the second Powerline adapter to use the same private encryption
key as the first so that they can communicate.
When the Power LEDs stop blinking and the Performance LEDs are lit solid green or
amber, the two adapters can communicate over the Powerline network in a secure way.
