For ECB/ECL-PTU Series controllers, the maximum length between two consecutive devices on the sub-network bus is 100 ft (30 m).
Subnetwork Bus Topology and EOL Terminations
Only a daisy-chain topology is acceptable for the room device subnetwork bus. T-connections are not allowed.
For controllers other than ECB-600 or ECL-600, only the EOL terminations of the last subnetwork bus device must be 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, because its internal EOL termination is permanently enabled.
The maximum number of room devices that a given controller model can support is indicated in the table of section
