Daisy-chain (no T-connections)
Most room devices have two RJ-45 female pass-through
connectors to facilitate the daisy-chain connection of room
devices.
For the EC-Multi-Sensor: An optional ECx-Subnet Adapter
(Y-splitter) is available to facilitate the daisy-chain connec-
tion of room devices. The ECx-Subnet Adapter must be con-
nected directly to the EC-Multi-Sensor and its length cannot
be extended.
Must be set / enabled on the last room device only. This
does not apply to the ECx-Display.
