    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.

    Weight: 1.87 lb (0.85 kg) Although the CEN-CN does not support a program being loaded, the version listed 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).

  • Page 10: Configuration Setup

    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.

  • Page 11: Obtaining Communications

    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.

    Crestron customer service for further information. Initial IP Setup NOTE: This initial IP setup MUST be done via the PC port of the CEN-CN. Before performing the procedures in this section, refer to “Obtaining Communications” on page 7 for cabling instructions. Thereafter, communications may be achieved by using the Crestron Viewport to connect directly to the IP address assigned to the CEN-CN.

    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.

  • Page 22: Communications

    The Crestron Viewport may be used to communicate with the CEN-CN via Ethernet. This is useful for changing the IP Table or updating the UPZ. The CEN-CN needs to be configured via the serial port for the first time (IP Address, etc). Refer to “Initial IP Setup”...
