8: Updating Software
Via FTP
The SCS software resides on the Lantronix FTP server (ftp.lantronix.com). Most of these
files are binary data, so the binary option must be used to transfer the files. All released
files are in the
pub
directory. Always download the README file in the
pub
directory
before downloading anything else; it contains a list of available software files. To log into
the FTP server, type
anonymous
as the username and enter your full email address as
the password.
Reloading Software
The SCS stores software in Flash ROM to control the initialization process, operation,
and command processing. You can update the contents of Flash ROM by downloading a
new version of the operational software via EZWebCon, TFTP, FTP, or MOP. Regardless
of which protocol you use to update Flash ROM, the following points are important:
The Flash ROM software file name should not be changed.
The download file should be world-readable on the host.
The path name has a sixteen-character length limit.
The file name has a twelve-character limit for the filename.
Note:
If you experience problems reloading Flash ROM, refer to
