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.

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
Operations Guide - DOC. 5721
Ethernet/Cresnet Interface: CEN-CN • 5
Ethernet/Cresnet Interface
Crestron CEN-CN
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 <
40,000
L x LF
Where: R = Resistance (refer to next table).
L = Length of run (or chain) in feet.
LF = Load factor of entire run (or chain).
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.

IP Table Setup
The CEN-CN may have the IP Table set through Crestron Viewport via direct
connection to the PC port or connected via TCP/IP once the IP Address of the
CEN-CN has been set. Just as each Cresnet device is assigned a Cresnet NET ID,
e.g. 03 through FE, to be used when programming, a CEN-CN is assigned an IP ID
which also may range from 03 through FE.
NOTE: Make sure that in the “Add IP Entry Table Dialog Box”, the “Set as
Master” checkbox is selected as shown below to specify the IP address of the system
to be designated as the host control system.
Add IP Entry Dialog Box
NOTE: The CEN-CN has a limit of one entry that may be entered into the IP table.
Although the entry may be placed anywhere in the table (position 03 to FE),
attempting to place more than one (1) non-zero entries in the table will result in an
error message.
Changing the IP Table via Crestron Viewport
You can modify the corresponding IP address for any IP ID by changing the IP table
directly. From the Crestron Viewport, first establish communications with the CENCN, then select Functions | Setup IP Table then click the Retrieve Current IP
Table from Control System button. This will extract the IP table from the CEN-CN

and list it in the dialog box. Modify or delete existing entries or add new ones. When
all the necessary changes have been made, save the new table to disk and/or load it
back into the unit. Do not overwrite the IP table in the CEN-CN the next time the
program is uploaded, unless the addresses in the program supercede those in the
current IP table.
NOTE: For more detailed information, refer to the SIMPL Windows help file by
selecting Help | Help Topics. Select the Index tab, type in IP table, then select
Changing IP Addresses without Changing the Program.
Crestron e-control™ IP Table Information
It is extremely important that the IP ID in the SIMPL Windows program match the
IP ID (sometimes called the Cres ID) in the IP Table of the CEN-CN.
Hookup Diagram for Normal Operation
When operating the CEN-CN under normal conditions, refer to figure on the next
page for a typical connection diagram. Other than making the power connection last,
complete the connections in any order.
CAUTION: When the ETHERNET port is connected to a larger network via a hub,
make sure that a straight (non-crossover type) Ethernet cable is used and that the
cable is NOT connected to the UPLINK port of an Ethernet hub. The cable is not
provided.
CAUTION: If making connections to the RJ11 NET modular port, use the Crestron
6-conductor modular cable provided, DO NOT use 6-conductor telephone cables.
Telephone cables are wired in a crisscross fashion and are not compatible with
Crestron equipment. For further information, refer to the latest revision of 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. New users are required to
register in order to obtain access to the FTP site.
CAUTION: If making connections to the CEN-CN Cresnet peripherals from the
NET 4-wire ports, refer to “Cresnet Wiring” on page 5.
NOTE: Operating power for the CEN-CN may be supplied either by the external
AC power pack (included) that provides 12VDC or supplied by 24VDC via the
4-wire CEN-CN Cresnet system wiring.
NOTE: The RJ11 NET modular port provides +24VDC only if power is supplied
via Cresnet wiring connected to the 4-wire NET port(s). The external AC power
pack does not supply power to this port.

SIMPL™ Windows® Example Program
SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use
programming language that is completely integrated and compatible with all
Crestron system hardware. The objects that are used in SIMPL are called symbols.
SIMPL Windows offers drag and drop functionality in a familiar Windows®
environment.
SIMPL Windows is Crestron's software for programming Crestron control systems.
It provides a well-designed graphical environment with a number of workspaces
(i.e., windows) in which a programmer can select, configure, program, test, and
monitor a Crestron control system.
NOTE: SIMPL Windows is not required directly by the CEN-CN. However, the
version listed in “Leading Specifications” on page 4 is required by the host control
system to support the CEN-CN. The example program is loaded into the host control
system which adds the CEN-CN as a device to the Cresnet system.
An example program (illustrated below) is available from the Downloads page
(EXAMPLES Library) of Crestron’s website (www.crestron.com). Search for
CenCnEx.ZIP that contains CEN-CN-EXAMPLE.SMW, associated macros required
to complete the program, and a README.TXT file that describes the example
program. Refer to the documentation supplied with the control system for
programming information.

Glossary of Terms
CIP
Cresnet (over) Internet Protocol is a combination of Cresnet and Internet protocols.
On a regular Cresnet network (such as a CNMSX talking to a CT-3000 touchpanel)
the low-level protocol that handles communications (such as "Digital 1 Pressed on
Cresnet ID 05") is called Cresnet Protocol. The same protocol is used when speaking
eControl devices (CEN-COM, CEN-IO, eControl touchpanels, TPS touchpanels over
ethernet, etc.), except that it is packaged into the IP protocol that is used on the
Internet and referred to as Cresnet over Internet Protocol.
CTP
Crestron Terminal Protocol is the protocol used when the viewport establishes a
connection via REMOTE -> TCP/IP CONNECT and only an IP Address is given.
The port number is assumed to be 41795, which is the port number that CTP uses for
communications.
CNX Control System
A CNX control system is any Crestron control processor in the CNX product line.
Currently, these include the integrated control systems CNMSX-PRO and the
CNMSX-AV and modular control system CNRACKX/-DP.
Cresnet ID
Cresnet ID, a unique identity code ranging from 03 to FE (in hexadecimal), is given
to all devices that communicate using the Cresnet network protocol.
Default Router
A default router is a router that sends packets within the local network to destinations
outside of the local network, or receives them from outside and propagates them onto
the local network. It is also referred to as a Gateway.
Ethernet Hub
Inexpensive four to 16 port devices that provide a way to physically tap into an
existing Ethernet connection and expand the plugs available, but do not perform any
packet routing.
Gateway
See Default Router above.
IP Address
Internet protocol address is a unique number that is used to represent every single
computer in a network. All the computers on the Internet have a unique IP address.
The format of the IP address is four numbers separated by dots (e.g., 198.168.0.1).
Operations Guide - DOC. 5721

Crestron CEN-CN
IP ID
The IP ID is a two-digit hexadecimal number that is used to differentiate a given
device from a group of Ethernet devices in a control system with the same IP
address. Just as the Net ID is used to distinguish between identical devices within a
SIMPL Windows program, the IP address for a specific IP ID in the control system’s
IP table must be set to the IP address of the given device. Furthermore, the IP ID in
the given device’s static master table must be set to the IP address of the control
system.
IP Mask
An IP mask is a pattern of bits in IP address format (e.g. 255.255.255.0) which, when
"and"ed with your IP address, produces a network address. If an outgoing packet's
network address has the same network address as the source of the packet, it is sent
on the local network wire, to be received by a device on that local network.
Otherwise, it is sent to the gateway, to be routed to a device existing on another
network. The IP mask for any device should be assigned by whoever manages the
local network. An IP mask is also referred to as a Subnet Mask.
IP MTU
IP MTU is the maximum packet size that the device can transmit. It is not necessary
to change this value from 1500 for an all Ethernet network.
IP Table
An IP table lists IP IDs and their corresponding IP addresses. This table is
maintained inside each CNX control system, though it may be generated by a SIMPL
Windows program, or edited manually using the Viewport utility.
MAC Address
MAC address is a unique hardware address assigned to every network device in use.
The MAC address is assigned by Crestron at the factory and is never changed.
MASTER LIST
Master list is a list of Crestron Internet Protocol (CIP) enabled devices that will be
informed of any changes in the state of the controlled device. The device accepts
commands from the addresses of these masters.
Network Address
A network address is a pattern of bits in IP address format that is shared by all
network devices on a given local network. For example, network address
192.168.2.0 describes the local network where all devices have an IP address of
192.168.2.x, where x is any value from 1 to 254.
NMS TRAP CATCHER
NMS trap catcher is the address of a SNMP monitoring station that sends any alarm
messages that the monitored device wishes to send.
Router
Router is a communications device that routes data between networks.
Subnet Mask
See IP mask above.

TCP/IP
TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is quite simply
a standard set of protocols that govern the basic workings of the Internet that was
implemented in 1982.
The TCP part is all about ensuring that data is transmitted correctly between two
computers. If any errors occur these are detected and the data is retransmitted. The
data transmitted is split up into small portions called data packets. The IP part of
TCP/IP is how these data packets are moved from one point to another. Each
computer on the Internet has a unique IP address and the data packets are moved
from the source to the destination through many different computers which is
controlled via TCP/IP. This protocol is used on the Internet and also by computers
which are part of a LAN.
