10.3 Nucleus 2450 Software Update
The Nucleus 2450 controller operating system software can be updated by updating the RTB
file used by the controller.
There are two methods to update the software:
• FTP access to the Nucleus controller, see section 10.3.1.
• Use Pbak Deploy to write to the Nucleus controller Compact Flash card and update
the software locally, see section 10.3.2.
10.3.1 Update using FTP
1. Use Workbench to check the IP address(es) of the Nucleus controller(s) to be
updated.
2. Use a client FTP program such as “FileZilla” or “SmartFTP” to open an FTP
connection to either one of the Nucleus controllers in the router. Use the IP address of
the Nucleus and the normal login:
User: 2450
Password: xyz
3. If Workbench is installed to the default directories, browse to the RTB directory
located in:
C:\Program Files\Snell\MCM\Controllers\2450\
4. Copy the file Pbl2450Controller.RTB to the controller over the FTP connection.
5. Make sure the copy was successful and close the FTP connection.
6. Open a terminal connection to the Nucleus Controller using a Telnet program such as
“HyperTerminal”, “Terraterm” or “Putty” (the TCP port is 50000).
7. Login to the terminal by typing login followed by the password pw2450
8. Type the command: Programdiskimage pbl2450controller
9. Wait for the message The new boot image was installed successfully.
10. Type the command reboot. Alternatively the controller can be rebooted by clicking
the “Force Reset of Controller” within Workbench.
11. When the Nucleus controller has rebooted, the new software should be running. You
can verify the version from the Workbench Configuration - Nucleus software versions
screen.
If the Nucleus 2450 controller is running an RTB file from Workbench release 3.14.2 or
later the preferred upgrade process is to use RollCall update and this is described in
section 9.4. The preferred upgrade method updates the controller software, firmware,
RollCall Command Set files and Webcontent files from a single zip file.
The RTB file version must be compatible with the version of Workbench that is installed.
If Workbench is installed in the default location on a 64 bit Windows computer then it will be
located in the “Program Files (x86)” directory.
