142 ECLYPSE APEX
Cat 5e Cable Subnetwork Bus Topology and End-of-Line Terminations
The EOL termination settings for the Cat 5e Cable subnetwork data bus will vary depending on the
type of controller the room device or extension module is connected to. By default, all room devices
and ECx-4XX Series I/O Extension Module EOL terminations are factory set to OFF (except for the
EC-Multi-Sensor and EC-Multi-Sensor-BLE).
For the Cat 5e Cable subnetwork data bus, only a daisy-chain topology is acceptable, and T-connections are not
allowed. For the EC-Multi-Sensor, EC-Multi-Sensor-BLE, and ECx-Display, an optional ECx-Subnet Adapter (Y-
splitter) is available to facilitate the daisy-chain connection of these devices. The male-end of the ECx-Subnet Adapter
must be connected directly to the device and its length cannot be extended.
ECx-Subnet Adapter (Y-Splitter)
The ECx-Subnet Adapter is also used with a controller to connect to an ECx-Display and to one or more room
devices. See Subnetwork Data Bus Length. In this scenario, the male-end of the ECx-Subnet Adapter must be
connected directly to the controller’s Subnet Port and its length cannot be extended.
EOL Terminations
When one or more room devices are connected to an ECLYPSE controller’s
Subnet Port
, only the
EOL terminations of the last room device is set to ON. All other room devices on the subnetwork data
bus must have their EOL terminations set to OFF. The controller must be the first device on the Cat 5e
Cable Subnetwork data bus as its internal EOL termination is permanently enabled. The ECx-Display
does not have any EOL terminations to be set and as such should not be installed as the last device
on the subnetwork bus. See Subnetwork Data Bus Length.
Please refer to the devices Installation Guide for EOL jumper or dip switch locations.
