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. e-Control Capable Cresnet System with CEN-CN ETHERNET HUB HOST CONTROL SYSTEM (ETHERNET CAPABLE) CRESNET PERIPHERAL UPLINK TO REST OF ETHERNET CEN-CN CRESNET PERIPHERAL CRESNET PERIPHERAL WIRING LEGEND CRESNET ETHERNET 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.

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 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. Wire Gauge Values RESISTANCE (R) WIRE GAUGE 4 6 10 15 13 16 18 20 22 24 (Double-CAT 5) 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.

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.

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., 220.127.116.11). Operations Guide - DOC. 5721 Glossary of Terms • 23 Ethernet/Cresnet Interface 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. 24 • Glossary of Terms Operations Guide - DOC. 5721 Crestron CEN-CN Ethernet/Cresnet Interface 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.
