Crestron CEN-CN Ethernet/Cresnet Interface 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”.
Ethernet/Cresnet Interface Crestron CEN-CN 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.
Crestron CEN-CN Ethernet/Cresnet Interface 12VDC .5 A 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.
Ethernet/Cresnet Interface Crestron CEN-CN ETHERNET This 8-pin, 8-position RJ45 port connects the CEN-CN to a 10BaseT Ethernet/LAN or WAN via a hub. Refer to the table below for the pinouts. A standard (straight, non-cross-over type) Ethernet cable is required, but not supplied. NOTE: This port should NOT be connected to the UPLINK port of an Ethernet hub.

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).
Crestron CEN-CN Ethernet/Cresnet Interface Before installing any development tools, confirm that all other applications such as Microsoft® Office, etc. are closed. The website and CD provide instructions for installing the various tools. When initiating a custom install from the CD, the user is presented with a list of the software programs, documentation, and other resources.

Ethernet/Cresnet Interface Crestron CEN-CN Port Settings Dialog Box 8. Select Diagnostics | Check Operating System Version (alternatively, depress F5) from the Viewport. The Viewport may display a window as it scans various baud rates. Eventually, a message should appear in the Incoming section showing a version number. Such a response indicates that communications have been established. If a “No Communications with Rack” error message opens, proceed to “Troubleshooting Communications” on page 10.
Crestron CEN-CN Ethernet/Cresnet Interface Updating the CEN-CN The CEN-CN contains an Operating System, a Monitor ROM, and TCP/IP Stack. All three are separate components but packaged together in a Control System Update File. Control system update files have the UPZ extension. It is often necessary to update a control system if new features have been implemented (such as support for new hardware or new language constructs) or if programming “bugs” have been corrected. NOTE: SIMPL Windows version 1.40.
Ethernet/Cresnet Interface Crestron CEN-CN Update Control System Dialog Box NOTE: After a file is selected, the “Update Control System” dialog box, as shown below, will query the CEN-CN to determine what versions of the Operating system, Monitor ROM, and TCP/IP Stack are currently running. 4. To start the transfer, click the Send button as shown below. The transfer dialog will display the progress in updating the selected components.
Crestron CEN-CN Ethernet/Cresnet Interface 5. As a result of the update, a dialog box (similar to as shown below) may open and the SIMPL program (and possibly SIMPL+ modules) must be cleared. As shown below, click the Yes button. 6. Upload the SIMPL program and SIMPL+ modules after the transfer is complete. Continue with transfer? Selection Box Ethernet Configuration This section explains how to configure a CEN-CN to communicate over Ethernet using the TCP/IP.
Ethernet/Cresnet Interface Crestron CEN-CN Set IP Information via Viewport 2. Observe a dialog box similar to as shown below. As shown, the CEN-CN does not have an IP address assigned to it. IP Address Dialog Box 14 • Ethernet/Cresnet Interface: CEN-CN Operations Guide - DOC.
Crestron CEN-CN Ethernet/Cresnet Interface 3. Refer to the two tables below and enter the network IP values. NOTE: If an invalid IP address is entered, the subnet mask may be CHANGED AUTOMATICALLY BY THE EQUIPMENT to an appropriate subnet mask. NOTE: To TURN OFF the TCP/IP stack, an IP address of 0.0.0.0 can be entered, no IP Mask or Default Router would be required. SETTINGS FOR NETWORK WITH NON-CRESTRON EQUIPMENT Recommended Settings IP Address 172.16.X.Y IP Mask 255.255.0.0 Default Router 0.0.0.

Crestron CEN-CN Ethernet/Cresnet Interface 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.
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.
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.
