Network Architecture
The following sections provide information about the Cresnet network architecture that should
be taken into consideration when designing a Cresnet network.
Maximum Network Size
The maximum size of a Cresnet network is dependent on the system design:
l
A single Cresnet server supports up to 25 client devices with a maximum aggregate cable
length of 1,500 ft (457 m).
l
A Cresnet network can be expanded to contain up to 90 client devices using Cresnet hubs.
Cresnet hubs also allow for longer cable runs. For more information, refer to
Cresnet Hubs
(on page 9) .
l
A Cresnet network can be further expanded to contain over 90 client devices using
Ethernet-to-Cresnet bridges. For more information, refer to
Ethernet-to-Cresnet Bridging
(on page 11) .
Network Topologies
Cresnet network systems can be designed using any of the following network topologies. A
topology should be chosen that best suits the needs of the particular Cresnet installation or
space.
Home-Run Topology
For home-run topologies, wiring is run from the Cresnet server to a single Cresnet client.
A distribution block is typically used in home-run topologies to allow the Cresnet server to
provide power and data to multiple Cresnet clients from one central location in the room. For
more information, refer to
Cresnet Distribution Blocks (on page 6) .
Daisy-Chain Topology
For daisy-chain topologies, wiring is run from the Cresnet server to a Cresnet client. For
subsequent Cresnet clients, wiring is either run from a second port on the prior Cresnet client, or
wires are doubled in the connector. This daisy chain can continue for up to 25 client devices or a
for total run of 1,500 ft (457 m).
