Figure 47: Example of the Distribution of the Total Subnetwork Data Bus Length Example
The maximum length of the Cat 5e cable subnetwork data bus used to connect a controller to
an ECx-display as a stub is 6.5 ft. (2m). The maximum total length of the Cat 5e cable subnet-
work data bus remains 1 000 ft. (300 m). When other Cat 5e cable subnetwork devices are
used, use an ECx-Subnet Adapter to connect to those devices.
