About the Subnetwork Bus
The ECB-600 UUKL controllers use the Subnetwork bus to support the ECx-400 UUKL I/O Extension Modules through the controllers Subnet+ and Sub-
net- terminals with 2-wire shielded cable.
The ECB-600 UUKL controllers also use the Subnetwork bus to support one or more Allure Series Communicating Sensor(s) using standard structural
(Cat 5e) cabling.
Subnetwork Bus Total Length
The total maximum length of all Subnetwork buses, including both the length of the Allure Series Communicating Sensor Subnetwork bus and the
ECx-400 Series Subnetwork bus is 300 m (1 000 ft). The maximum length of the Allure Series Communicating Sensor Subnetwork bus is 200 m (650 ft).
The maximum length of the ECx-400 Series Subnetwork bus is 300 m (1 000 ft).

Subnetwork Bus Topology and EOL Terminations
When ECx-400 Series I/O Extension Modules are installed with an ECB-600 or ECL-600 Series controller, only the EOL terminations of the ECB-600 /
ECL-600 controller and the last I/O Extension Module are set to ON. All other I/O Extension Modules must have their EOL terminations set to OFF.
When ECx-400 Series I/O Extension Modules are installed with an ECB-600 or ECL-600 Series controller and with Allure Series Communicating Sen-
sors, only the EOL terminations on the last I/O Extension Module and the last Allure Series Communicating Sensor are set to ON. The ECB-600 /
ECL-600 and all other I/O Extension Modules and Allure Series Communicating Sensor s must have their EOL terminations set to OFF.
