For more information and detailed explanations on network topology and wire length restrictions, refer to the Network Guide, which can be downloaded
from our website.
It is important to use proper network terminators depending on the type of network topology used. Failure to do so
may result in communication errors between controllers.
Selecting Network Terminators
For a bus topology, 2 network terminators are required (1 at each end of the bus topology channel). For a free topology, 1 network terminator is required
and it can be put anywhere on the channel.
When used with anAllure EC-Smart-Vue Series Communicating Sensor, the network can be accessed at the sensor’s audio plug port for commissioning
and maintenance purposes, when the two Net to Subnet Port Settings jumpers inside the ECL Series controller are set to Enable (for jumper location,
see Figure 9). This will connect the main L
ON
W
ORKS
network to the subnet Cat5e cable.
Recommendation: Only a limited number of controllers on a L
ON
W
ORKS
network segment should have their Net to
Subnet Port Settings jumpers enabled. Enabling too many Allure EC-Smart-Vue sensors with network access may
cause network communication issues. If there are any network communication problems, refer to the
Troubleshooting Guide.
The Cat5e cable length is restricted by the maximum allowable subnetwork bus length (see the Allure EC-Smart-Vue Hardware Installation Guide for
more information).

Wireless Installation
When connected to a Wireless Receiver, controllers can receive input signals from a wide selection of wireless devices. Compatible wireless devices in-
clude temperature sensors, duct sensors, window/door contacts and light switches. These devices are easy to install, and can be mounted on a wide
range of building materials.
Before connecting any wireless equipment to the controller, refer to the Open-to-Wireless Application Guide.
