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.

Physical Description
The CEN-CN, shown below, is housed in a black enclosure with silk-screened labels
on the front and rear panels. On the front panel are six light-emitting diodes (LEDs)
for indicating the status of the unit, the attached device(s), and the connected
Ethernet. All connections are made through on the rear panel ports, a Crestron
6-conductor modular cable and two 4-pin connector plugs are provided. There are
four rubber feet on the base of the unit for stability and to prevent slippage.

This DC power socket connector is used to supply power via an external power pack.
Crestron recommends specific power packs for its devices. The recommended power
pack for the CEN-CN is Crestron part number PW-1205 (PWI-1210 for
international use). If a power pack other than this Crestron model is obtained, verify
that it meets the required specifications and polarity as shown after this paragraph.

is required by the host control system to support the CEN-CN. The latest software
version can be obtained from the Downloads page (SIMPLWIN Library) of
Crestron’s website (www.crestron.com). New users are required to register in order
to obtain access to the FTP site.

Cresnet Network Wiring
NOTE: If making category 5 connections to the Cresnet peripherals, refer to the
latest revision of the Cresnet Mini Network CAT 5 Interconnect Drawing (Doc.
5819). This document can be obtained from the Downloads page (CABLES and
MANUAL Libraries) of Crestron’s website (www.crestron.com). Search for
CAT5.PDF. New users are required to register to obtain access to the FTP site.
NOTE: If making modular connections to devices in the Cresnet system, review the
latest revision of the Network Modular Cable Requirements (Doc. 5682). This
document can be obtained from the Downloads page (CABLES and MANUAL
Libraries) of Crestron’s website (www.crestron.com). Search for MODULAR.PDF.
When calculating the wire gauge for a particular Cresnet run, the length of the run
and the load factor of each network unit to be connected must be taken into
consideration. If Cresnet units are to be daisy-chained on the run, the load factor of
each unit to be daisy-chained must be added together to determine the load factor of
the entire chain. If the unit is a home-run from a Crestron system power supply
Ethernet/Cresnet Interface Crestron CEN-CN
6•• Ethernet/Cresnet Interface: CEN-CN Operations Guide - DOC. 5721
network port, the load factor of that unit is the load factor of the entire run. The
length of the run in feet and the load factor of the run should be used in the following
resistance equation to calculate the value on the right side of the equation.
Resistance Equation
R = Resistance (refer to next table).
L = Length of run (or chain) in feet.
LF = Load factor of entire run (or chain).
R < L x LF
40,000 Where:
The required wire gauge should be chosen such that the resistance value is less than
the value calculated in the resistance equation. Refer to the table below.

NOTE: All 4-wire Cresnet wiring must consist of two twisted-pairs. One twisted
pair is the +24V conductor and the GND conductor and the other twisted pair is the
Y conductor and the Z conductor.
NOTE: When daisy-chaining Cresnet units via 4-wire Cresnet wiring, always twist
the ends of the incoming wire and outgoing wire which share a pin on the network
connector. After twisting the ends, tin the twisted connection with solder. Apply
solder only to the ends of the twisted wires. Avoid tinning too far up the wires or the
end becomes brittle. After tinning the twisted ends, insert the tinned connection into
the Cresnet connector and tighten the retaining screw. Repeat the procedure for the
other three conductors.
Configuration Setup
To configure the CEN-CN, a local PC that contains a Crestron Viewport is required.
The Viewport is one of the development tools that is part of Crestron’s SIMPL
Windows or VisionTools Pro-e (VT Pro-e) control software applications.
Installing Crestron Development Tools
Crestron control software is available in an electronic form; CD-ROM, email, or
from Crestron’s website. Regardless of how and from where the software is
obtained, this section provides the necessary installation steps.
NOTE: The latest versions of these applications are available from Crestron’s
website (www.crestron.com). Crestron ControlCD also contains a version (which
may not be as current as the website version). To obtain a free copy of the CD-ROM,
contact Crestron at 1-888-CRESTRON [1-888-273-7876]. Alternatively, complete a
literature request from the Crestron website to obtain one.
