Client Device Distribution

A Cresnet network system with a single Cresnet server can provide power and data to up to 25
client devices with a maximum cumulative wiring run of 1,500 ft (457 m). Cresnet networks can
be expanded via Cresnet distribution blocks and Cresnet hubs. Each device type and supported
models are described in the following sections.

Cresnet Distribution Blocks

Cresnet distribution blocks allow for multiple Cresnet wiring runs to be terminated to one central
location within a room. The Cresnet distribution block is connected to the Cresnet server and
distributes power and data from the server to all connected clients. Cresnet distribution blocks
are commonly used in home-run network topologies, but can also be used to power client devices
off of a central Cresnet hub.
The following Cresnet distribution blocks are available.

Cresnet Distribution Block

The CNTBLOCK is a parallel distribution block designed to facilitate the termination of multiple
Cresnet wiring runs in an equipment cabinet, closet, or beneath a table.
