Ethernet/Cresnet Interface:
CEN-CN
Description
Functional Description
The CEN-CN is used to connect Crestron remote control system (herein referred to
as the Cresnet system) equipment to a Crestron e-Control
™ capable control system
through an Ethernet/local area network (LAN) or wide area network (WAN). A
combination of Crestron devices in a remote location may be hard-wired to a
CEN-CN to create a “CEN-CN Cresnet system”. Through an Ethernet using standard
Internet protocol (IP), the CEN-CN Cresnet system connects to a “host” control
system that is in another location. Thus, the devices attached to the CEN-CN Cresnet
system become part of the host control system. The diagram shown below illustrates
a sample Ethernet/Cresnet system that contains a CEN-CN.

To establish communication with the host control system, IP information is loaded
locally into the CEN-CN via the Crestron Viewport through a personal computer
(PC). In the host control system, the IP information is loaded and the program with
the CEN-CN defined on Ethernet that contain the Cresnet identifications (NET IDs)
of the CEN-CN Cresnet system devices is loaded.
Operating power for the CEN-CN may be supplied either by the external AC power
pack (included) that provides 12 direct current volts (VDC) or supplied by 24VDC
via the 4-wire CEN-CN Cresnet system wiring.
