I uploaded a logo to display on the upper left corner of the Web Configurator login screen and
access page but it does not display properly.
Make sure the logo file is a GIF, JPG, or PNG of 100 kilobytes or less.

The NXC’s traffic throughput rate decreased after I started collecting traffic statistics.

I can only see newer logs. Older logs are missing.
When a log reaches the maximum number of log messages, new log messages automatically overwrite
existing log messages, starting with the oldest existing log message first.
The commands in my configuration file or shell script are not working properly.
• In a configuration file or shell script, use “#” or “!” as the first character of a command line to have the
NXC treat the line as a comment.
• Your configuration files or shell scripts can use “exit” or a command line consisting of a single “!” to
have the NXC exit sub command mode.
•Include write commands in your scripts. Otherwise the changes will be lost when the NXC restarts.
You could use multiple write commands in a long script.
Note: “exit” or “!'” must follow sub commands if it is to make the NXC exit sub command
mode.
I cannot get the firmware uploaded using the commands.
The Web Configurator is the recommended method for uploading firmware. You only need to use the
command line interface if you need to recover the firmware. See the CLI Reference Guide for how to
determine if you need to recover the firmware and how to recover it.
