Updating the Control System
Each CNMSX contains an operating system (OPS), a Monitor ROM, and when the
optional CNX Ethernet expansion card is installed, a TCP/IP Stack. Although each is
a separate component, they are 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 bugs have been corrected. The following
procedure is recommended to load a new UPZ file into the CNMSX:
NOTE:
UPZ files only pertain to X generation control systems and systems
implementing the ST-CP. UPZ files are not used for older models such as the
CNRACK, CNMS, and CNLCOMP-232. Consult the appropriate documentation for
each of these products to perform updates.
NOTE:
In order to load the latest update files, the CNMSX must have v2.05 or later
(this includes v5.01.35 or later) of the Monitor ROM. This requirement should only
impact a few users; refer to "Special Consideration for Updating the Control System"
on page 33 for details.
1. Establish communications with the CNMSX by following the steps
listed in "Obtaining Communications" on page 24.
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.
