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.

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.
