User Manual

Warning: Never replace your PLM while the ISY is running because it will assume it is still
connected with the old PLM. The ISY will appear to work, but it will be writing the address of the
old PLM into the device links, thus you will not see devices updates etc.
If this menu option is selected, the ISY goes through all INSTEON devices looking for old and
new PLM address links. If an old PLM address link is found, it replaces it with the address of the
new PLM and adds the corresponding device link to the new PLM.
To replace a PLM:
i. Unplug ISY from the power outlet
ii. Unplug the PLM from ISY and power outlet
iii. Connect ISY’s port A to the new PLM
iv. Plug the new PLM into a power outlet
v. Plug ISY into a power outlet
vi. Open the browser to ISY’s GUI and wait for system initialization to complete
vii. Click on the Restore Modem (PLM) menu option
4.1.7 Remove Modem (PLM)
Before selecting this function, create a backup ISY file.
The modem (PLM) is the communication bridge between the ISY and the INSTEON devices.
Without the modem and the links you cannot control or get status from the INSTEON devices.
When the communication links were established via the Link Management Menu, the PLM and
INSTEON devices adds each device addresses it is linked to, in its own link table. The ISY also
stores the PLM’s address.
If you need to remove a modem from your lighting network, select this function. It will disconnect
the ISY from the PLM and the PLM from all INSTEON devices in the network, removing all the
links between them. This ensures orphaned links do not exist in the INSTEON devices when the
PLM is removed from the lighting network. Also, it ensures the ISY is not looking for the removed
PLM.
Orphaned links are links between two devices where one is no longer in the network. Orphaned
links will affect the lighting network performance. A device with an orphaned link to a missing
PLM will create unnecessary network traffic by trying to communicate with the PLM multiple
times. This in effect will slow down the network response.
All ISY programs, Triggers or Schedules, will not work when you remove the modem from the
lighting network. Also, the actual status of all INSTEON devices will not be synchronized with the
status reported on the screen.
4.1.8 Enable/Disable Internet Access
In order to achieve remote/internet access, you will need to setup your router for port forwarding.
Port forwarding allows the ISY’s port to be seen over the internet.
The controller default setting is with internet access disabled. If you would like to enable internet
access to the controller select this option. It is reversible and you will be presented with the
Disable Internet Access menu option.
