7 How to use the NMK Pushbutton
This section describes how to add new devices to, or remove old devices from a
HomePlug AV logical network(AVLN), both can be accomplished using a NMK
pushbutton press.
Operation progress and outcome can be monitored by observing the behavior of
the Power LED.
7.1 Forming a HomePlug AV logical network
When two devices with different NMK values are connected to the same powerline
and want them to form a logical network, do as follows:
(1) Press the NMK button on the first device A for less than 3 seconds.
(2) Press the NMK button on the second device B for less than 3 seconds. The
button on B must be pressed within 1 minute
(3) Wait for connection to complete.
The Power LED on both devices will flash evenly at 1-second intervals until the
operation succeeds or fails. It will illuminate steadily on successful completion. If an
error occurs, the Power LED on the ‘adder’ will flash unevenly until the pushbutton
on the ‘adder’ is pressed again or the ‘joiner’ is reset by holding the pushbuttons
down for more than 10 seconds.
