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 1.40.07 or later is required to update the UPZ. When the UPZ is loaded, the program and SIMPL+ modules will be erased so they must be reloaded after a UPZ is loaded.

The following procedure is recommended to load a new UPZ file into the CEN-CN.

1.Establish communications with the CEN-CN by performing “Obtaining Communications” on page 7.

2.From the Crestron Viewport, select File Transfer Update Control System as shown below.

Accessing the Update Control System Dialog Box

3.The Update Control System dialog box, shown on the next page, offers the option to enter the path name of a new update file. If the path name is not known, use the Browse button to navigate to a list of available update files. When browsing, choose only update files with a UPZ extension.
