On each of the parent and child devices, connect the blue plug of the daisy chain cable to the
EXT IN terminal (blue) and the green plug to the EXT OUT terminal (green).
After the connection is established, the product is now ready for a connection, the indicators

If you configure the child settings for the parent device and the parent settings for the child device, unplug the
daisy chain cable once. A notification sound rings, and the child device starts restarting. After the child device is
restarted, repeat step 4 and subsequent steps.
