2E. Network Bridges
2.0 Network Topology
The Network topology is the connection scheme between Networks. C-Bus
®
allows up to 7 Networks
in depth (i.e. 6 bridges), but to minimise transmission delays, Network depth should be minimised.
This is illustrated in the topologies below. Which can be found at the bottom of the tree for a particular
project.
On the computer screen the physical Network cable is represented by a Pink line and the square
boxes with the diagonal line indicating the bridge.
The Topology is drawn for you by the software, dependent on what bridges are shown in the units
on the Database
2.1 Daisy Chain
Figure 2 - Daisy Chain Topology
Figure 2 Illustrates a project that contains four Networks wired in series (Daisy Chain)
For messages to be sent from the Network (251) 3rd oor to Network (254) ground oor must pass
through 3 bridges.
