Subnetwork Bus Topology and EOL Terminations

Only a daisy chain topology is acceptable for the room device subnetwork bus. T connections are not allowed.

Some controller models support the connection of other devices to the Subnet Port as part of the Smart Room Control solution (see the controller's

datasheet for more information).

For non ECB-600 or ECL-600 Series controllers, only the EOL terminations of the last subnetwork bus device are set to ON. All other subnetwork bus

devices must have their EOL terminations set to OFF. The controller must be the first device on the Cat 5e Cable Subnetwork bus as its internal EOL ter-

mination is permanently enabled.

See Table 1 for the number of Allure EC-Smart-Vue sensors that a given controller model can support.

When one or more Allure EC-Smart-Vue sensors are installed with an ECB-600 or ECL-600 (without an ECx-4xx IO Extension Module), only the EOL

terminations on the ECB-600 / ECL-600 and the last Allure EC-Smart-Vue sensor are set to ON. All other Allure EC-Smart-Vue sensors must have their

EOL terminations set to OFF.
