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.
