Web Server Access

You can optionally use SocketServer (or the NS-Link equivalent) to access the
DeviceMaster LT configuration and reset many values to their default values.

Some of the values require resetting the DeviceMaster LT to take effect. After
changing the IP addresses and resetting the DeviceMaster LT, it will not
reconnect automatically. You will need to use the new IP address to reconnect.

Note: The authentication method and the password cannot be changed using

SocketServer.

To reset authentication, see

Serial Port Access

on Page 135 or use the

RedBoot Command Overview

on Page 107.

To reset the password, see

Configuring Passwords

on Page 106 or
