Crestron electronic CEN-CN manual Obtaining Communications, Hookup Diagram for Configuration

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. For each item, set or clear a checkbox to the left of the item to direct the installation program whether to install that component onto the hard drive. The size of the each item installed determines how much disk space is required. Each development tool contains a help file that can be opened from the Help pull-down menu. Refer to these files for additional information.

Obtaining Communications

To configure the CEN-CN, it is necessary to first obtain communication with the device. Communication can be established via the CEN-CN rear panel PC port. To perform the configuration of the CEN-CN, the provided 6-conductor modular cable and an RJ11 to DB9F adapter (not supplied) are required. The adapter is available commercially or contact Crestron customer service for part number 15556. If obtained, proceed to “Hookup Diagram for Configuration” on page 7.

Configuration Cable Fabrication Specifications

In the event that an RJ11 to DB9F adapter is not available, the table and the diagram below are provided so that the cable can be fabricated on site.

Hookup Diagram for Configuration

When performing the configuration, refer to the figure on the next page for a typical connection diagram. Complete the following steps in the order provided to ensure proper connection.

NOTE: If an RJ11 to DB9F adapter and/or modular cables are not available, refer to “Configuration Cable Fabrication Specifications” on page 7.

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.
