2. Verify that the new software is available in the PC. The download software for the serial upgrade
must have a “.dwn” extension, e.g., nxg01_05.dwn.
3. To have the shortest download time possible, set the gateway to use the highest RS-232 speed
allowable on the PC. In this example, a download speed of 57600 baud will be used. Set the
console speed of the gateway to 57600 baud by issuing the command:
>console-speed-bps 57600
4. Change the baud rate of the PC to match the gateway. Remember that with Hyperterminal, you
must disconnect the session and re-connect before the changes will take effect. Verify the PC
communicates with the gateway again.
5. If the gateway configuration has been password protected, you must first unlock the protection
with the command:
> unlock enable-configuration= password
(when the configuration is unlocked, the gateway prompt ends with the characters ‘#>. In locked
mode the prompt does not include the ‘#’ character).
6. Issue the command:
>directory
to view a list of files stored in Flash PROM as well as the available free space. Verify that there
is enough free space in flash PROM for the new file. The space required will be the size of the
nxgNN_NN.dwn file divided by 2.5. If there is not enough space in Flash PROM delete one of
the program files to make up space (use command >delete filename).
7. Start the download process by typing:
>download-file destination=nxgNN_NN method=inline
where NN_NN file is new version of software being installed.
8. The gateway will return with the following:
“ Send the file ... if incomplete, end with a line with just a period ”
When you get this prompt, go to “Transfer-Send Text file…” in Hyperterminal and select the file
to be installed. The file must have a “.dwn” extension.
9. After the file is successfully installed issue the command:
>directory
to insure that the file has been loaded into memory.
10. Issue the command:
>set-default-program filename=nxgNN_NN
