13 INSTEON Device Notes
Some INSTEON devices require special care when used with the ISY. Some need to be
added to the system in a specific way, and some have unique options available when
configuring with the ISY. This section details some of this information and more.
As al ways, please refer to the manufacturer’s documentation first. Please consider the
following notes as a secondary source of information.
The following notes are sorted alphabetically by device name.
13.1 PowerLineModem (PLM)
53
The ISY uses the PowerLineModem (PLM) to interface with Insteon and X-10 signals. The
PLM sends Insteon and X-10 commands initiated by the ISY and receives Insteon and X-10
commands placed on the power-line by Insteon and X-10 devices.
Every Insteon device in your system must be linked to the PLM for the ISY to be able to
communicate with it. In this manner Insteon signals are secure. Insteon devices are linked
as a controller, a responder, or as both a controller and a responder. In addition, every
scene created with the ISY creates links in the PLM to each device in each scene. It is
through these links that the ISY can control scenes and track the status of devices.
X-10 devices do not require any links in the PLM. X-10 signals can be sent and received
freely, there is no security.
